I'm gonna say it, Metric? State of Alabama went Metric in the 60s on account of the Space Race. Some areas of the state you can still find speed limit signs in KPM and road signs in Kilometers, as well as International Road Signs. So, in 2nd grade in 68/69 school year our teacher Miss. Jackson taught us both Fractional SAE and Decimal Metric measurements.... Which still tickles me and makes me laugh for so many more reasons and why I have some weird nightmares.
@@Mike-bm6cf oh, I understand this question thanks to being in the Navy for a life time and going everyplace. Believe it or Not! You can tell where you are by the shape of the foot, or where your great-greats came from. Over all the American Foot is truly an American Foot and it reflects our Mixing Bowl Heritage. Over all it has a thin heel but wide forefoot area, and this is unique to the US and makes finding shoes an issue. Only New Balance uses a last (the form the shoe is constructed on) that fits American Feet the best. If the shape of the foot overall is wide from forefoot to heel, look to England and the British Isles for large shoes that are like bricks, small sizes but still wide South East Asia, Skinny small sizes Italy and the Northern Mediterranean area, Long and Skinny Africa. But for the most part, if you CAN find a US Maker of Shoes where they actually DO make the shoes on US Soil they should be making a shoe to fit you. If its made in China (number 1 maker of US brands) you'll find they make shoes to fit their own feet....which is why most brands you find lack large sizes and wide sizes. The maker simply does not believe us American Giants really exist ...well, not until we step on their toes with our great big feet.

@@geneard639 Its unusual, the USA have a decimal currency but imperial measurement system, okay it's historical but it followed the old UK measurement system, the only thing is the UK moved to decimal systems for both money and measurement back in the 70s. As with all systems the more complex they are the more likely errors will be made. As for using both systems at once, need I say more than the space shuttle mirrors. Of course free choice is important but at the expense of making costly errors, it wouldn't be my choice.
Father and son workshops are fantastic places to work,most are decent hard-working people and the family vibe is awesome and working becomes a joy rather than a chore.Well done guys,all my best wishes for the future!
I remember a machine shop that I used to deal with had an engine that they couldn't find the pin bushings for it without waiting for weeks. His solution was to buy bronze bushings that he machined the OD to size and trimmed them to length. Then he pressed them into the rods and bored and honed the ID to custom fit the pins. Even with the extra work, he came out cheaper and faster than waiting for the parts from his supplier.
Yes, I have known of examples like that. I worked briefly back in the early eighties for a company that produced envelopes. On one of their machines there was a grinding noise in the drive gearbox, and it turned out to be a defective shaft that was out of specs. Well, the machine was under warranty and after some back and forth with the manufacturer it was decided to wait for a replacement shaft. This amounted to water under the bridge and a machine that was down and could not be used thereby causing production to stop (there were other machines, but it still affected production). The company would have been better off to have made a new shaft (they did have a machine shop) but of course they wanted to exercise their warranty. Of course, by exercising their warranty they lost more than they gained. Sometimes it pays to go ahead and attack the problem with your own solution.
I trained in power stations leaving in late 1980s. We regularly had shafts and bushings made locally at a small fraction of OEM cost. Warranty was irrelevant of course.
@@billywird you've made a valid point and I would probably have done the same, but they might have refused to tamper with a machine under warranty because the manufacturer could refuse to assume that warranty later if something else went wrong and they found an unauthorized repair / non OEM part. If not for that reason, then that's a bad decision on their side.
You can not use full bronze bushings in the piston pins. OEM connecting rod pin bushings are made of steel with a fine layer of bronze in the inside, so they are stronger. Full bronze thick bushings are soft and they will compress with time and will increase its clearance, and later end in catastrophic failure to the engine. Never install full bronze bushings, only steel backed bushings with inside bronze layer can be used, as the OEM ones are made.

I work every day in my dads shop that he built and wish i was able to have had these sort of experiences of working alongside him. Also, you have a machine shop, make new bushings in your fancy lathe!
Lost mine when I was 1 so I never known how that relationship is. But at 50 now I have the pleasure of being a father to my daughter. Still there's a void there an the father son relationship is one of the most enjoyable thing with this channel.
About a year ago I cancelled cable and now just have an internet connection. I’ll watch this father son team any day over the junk they have on TV these days. Also as an old guy , a really old guy I think I can speak for the father in saying if we’re up to the father we would not be seeing this excellent content. It’s the son thats producing and directing this channel. Thank you to the both of you!

I used to fix electronic equipment in a hospital. It was amazing how many times we would encounter a problem and be told by the manufacturer we were the only ones having this problem. Once the manager phoned another hospital halfway across the country with the same equipment to see if we really were the only ones having this particular problem. They had been told the same thing by the manufacturer that we were told. We had to get health Canada involved to force them under threat of federal lawsuit before they admitted they knew about the problem all along and agreed to fix it.

Nothing like a father and son doing some honest work to distract me from the lunacy of the real world. Keep it up! I miss my dad, he kept my head level.
The chemistry between you both is what makes the videos so good, the people saying that it should only be one of you definitely don’t know a good thing when they see it.
When I retired 20 years ago manufactures an supplier's told me the same crap.Never had that happened before tells me it's time to find another supplier. Great video you two.
The one exception I have to that rule is if I hear "you're the first - and we need to figure out why this has happened to make sure it doesn't happen again" On the other side of it as a supplier (ISP) I've had to say to a customer "Something obviously changed if it was working yesterday - and if I had changed anything I'd have my phone ringing off the hook. I need you to think really carefully about what might have been altered on your system so we can both solve this issue" - at which point they'd remember a windows update or new piece of software installed on the system I've heard similar stories about "nothing changed" in mechanical stuff which involved an oil change and cheap taiwanese(*) filter which turned out to be full of debris (or in another case an "oil flush" after decades of no oil changes which upon engine autopsy was found to have dislodged accumulated gunk that found its way into critical galleys and blocked them entirely (*) It was the 80s - when "made in Taiwan" was taking off, "made in Japan" had long-transitioned to being consistently high quality, "made in China" was still in the future, "made in the USA" was a crapshoot for quality - some was still good and some was VERY VERY bad - "made in Britain" was generally regarded as "put it back on the shelf and pretend you never saw it. Better yet, sweep it into the garbage bin" and "Made in Germany" meant "high quality but utterly unaffordable"
It's interesting how critical folks can be of your tools and work processes from the perch of their couch or easy chair. I like to take care of my tools as much as the next man but in a successful operation like yours for example, I applause you both for staying on task and doing nice work for your customers. It's as clear as the nose on your faces to me that you are both doing a fantastic job.
Tbf it is easy to get a piece of metal to come off and get embedded in your skin. My grandfather has a piece of iron in his finger to this day from a similar worn down tool. It doesn't seem to bother him much, but if I had a choice between getting iron shards in my hands or not, I would prefer to remain shard free.
@SchwachsinnProduzent I understand how unpleasant that can be. I find metal fragments in my skin fairly regularly. It's just an occupational Hazzard. It's still a good practice to clean up your punches chisels and drivers to prevent those mishaps.
I wish your shop was in my area! I spent a couple of years working as an automotive machinist, back in the early 1980s. And I'm very impressed by the quality of your work and the standard of customer service you show. I just don't see that in the one local shop we still have. And I hate admitting it, but it's the shop that I worked in.
It’s a shame when a brand goes from being known for quality to building disposable products. I love that you are willing to accept the challenge of fixing something that others wouldn’t touch, take the time and go the extra miles to make it right.
Surely if they do not want to repair an item and the only option is to buy a new one, that makes the item disposable, in this case a disposable Kubota engine. Same old greed play from big corporations be it Apple, John Deer, Chrysler or Ford. The parts, subassemblies and or services are priced to prevent repair and to drive all independent repair shops out of the market. E. G. A broken charge chip on an Apple computer, manufacturing chip cost 60 cents retail. Apple refuses supply the chip to independents or allow the manufacturer to sell it to anyone else. The Apple solution is $1700 for a replacement motherboard or $1750 for a new laptop. In this case the laptop surely becomes disposable.
I used to work in a military machine shop as a civilian contractor and we used to get hercules 4 and 6 cylinder diesels to rebuild that had been sitting in a "Can Point" for decades buried in the dirt. Almost all of them had pistons that looked just like those Kabota's. We cleaned them up, used old rings as groove cleaners, spun the pistons on a lathe to smooth out the rough spots, and put them together. They made dyno numbers and held together every time! Low RPM engines don't need as much precision.
I pulled a 3TNV76 out of a "John Deere" tractor last year and had a local machine shop go through it. I bought all the aftermarket (Chinesium) parts for it, rods, pistons, piston pins, rings, bearings, gaskets and head and everything actually went together within spec which shocked me. 1 cylinder had to be sleeved due to a pin retainer coming out and putting a deep score in the cylinder. The price difference between the aftermarket parts vs factory Yanmar was ridiculously high. It would have been 2.5 to 3 times higher for the factory parts. Any time I do work for someone (I'm retired) I charge them a little something for my time chasing parts or on the phone or computer trying to round up parts. Time is money, especially if you're driving around going to the machine shop or local parts stores, gasoline isn't free...
Yes I had a friend of mine who charged for the rounding up of parts and going to suppliers and getting stuff (the errands that folks expect to come with the cost of the job). I did the same thing when I was a RPS P&D Contractor and owned my own package truck. I did work for other contractors and figured in my time running parts and such to do the repair work on their package trucks. As we had to provide a vehicle and driver as per our contract, I could do regular jobs like brake jobs and clutches and even other work that could be done over the weekends. This enabled a contractor to not have to rent a vehicle while his was tie up in a repair shop and was well worth the extra money spent with me. I also patched and repaired many items due to the fact that the package truck would be down waiting for parts.
We had a 4 cylinder Chevy car. At 15000 miles it needed a new exhaust system. We took it to a muffler shop. They didn't have the exhaust manifold which was just header pipe . Down in the middle of where the four pipes came together it rusted out because the heating from welding it caused it to rust fast. They called my wife to tell her they didn't have the part. She went to the Chevy stealership and they had one, $250 . This was around 1990. She asked why it was so much. The guy proudly said , " Because it's an original GM part" . When she told me I said, " Did you tell him the rusted out one with 15000 also was an original GM part. "
I drive a Fiat 1.3 diesel which was a Fiat & GM joint project. The only problems are stuff done to suit GM. The cam chain is a real pain to work on and lasts no longer than a cam belt. A Fiat cam belt would have made it one of the best engines ever.
Hi there from Australia,,, Diesel Fitter here,,, I was taught, if the piston grabs at the ring or above, its a coolant problem and if it grabs below the rings its a an lubrication problem,,,, love your vids ,,
Based on the damage I'd bet on that engine getting dusted, not so much a coolant issue. Coolant issue should have cooked the middle cyl not 1 then 2. Might even be bad injector made number 1 wash the cylinder then overheat residual thru cylinder wall overlap.
probably others have said this often - but the shop organization and cleanliness (like a kitchen - some are like new - others greasy and worn looking) - is truly impressive and a strong indcator of work standards being high.
For me , I’m an auto mechanic. Will be an honor having my Dad working with me on the shop I enjoy the dynamic with both of you guys and the knowledge shared by the cleaning guy . Good luck with your future. Thanks again.
I haven’t watched a video of yours for a long time and as for your son, he has matured tremendously is very knowledgeable. What I saw in the earlier videos was his humility and asking lots of questions. Now he knows and explains so much more but still is humble enough to ask about things he doesn’t understand. You are a great team!
I'm not a pro but I have learned a few tricks, this would require more machining but will get the job done & with the correct tolerances. 1- are there any business that do Industrial Hard Chrome Plating ? If you can't get the correct size bushings you could get the wrist pins built up with chrome but would have to re-bore the pistons to accept the bigger diameter wrist pin, and probably have to rework the wrist pin clip groove and maybe even larger. When I lived in Connecticut, I got involved in oval track racing, the owner / driver of the car owned an Industrial Chrome Shop, we would chrome our rocker arm shafts, crank journals ect., I hope you find what you need but you asked for suggestions, I hope I may have opened up a new avenue, love the videos, you guys ROCK !
How much does chroming cost vs the life extension/maintenance reduction benefit I get it matters in extreme load situations but does it matter in low load ones? My immediate worry about those blued bushings isn't about the sizing of replacements but about oil flow inside the rods or if squirters are needed. Ideally you don't want to ever see the engine come back with a simliar complaint The cleaning guy and woolly faced youth are both correct in wanting to see a failed engine in-situ to locate and correct the underlaying causes
Working in the industry that use primarily Kubota engines (grounds machinery) the radiator is usually the cause being blocked up with dirt and grass clippings. The water pumps fail regularly too. Great video, I've been inside so many of those engines.
Used to do a lot of work on my Kubota and learned real fast to keep the radiator clean when mowing! Got it a little hot and at the end of the day when I idled it down the oil light came on because of the temperature. After cleaning the radiator the temperature came down and it was fine. Guess I caught it in time!!
@@garybulwinkle82 my grasshopper is terrible for the radiator getting clogged fast. in the summer its a habit of looking at that temp gauge all the time or at so many laps in the yard
Water pump failures are virtually always a result of "wrong coolant" or ""mixed coolants" Clogged up rad externals aren't usually THE failure cause but a symptom of the same "don't care" operator attitude that has destroyed engine internals Coolant isn't coolant isn't coolant - and the types used absolutely do matter (think: Electrolytic activity due to dissimilar metals. Most good coolants have chemicals added to minimise the damage from this) A lot of coolant issues in small engines are because almost all Japanese engines sold since the 1990s are designed to use Diaqueen (the same light blue near-transparent coolant found in most Japanese cars) but people just shove any old cheap green stuff in there(*) - if they bother using "antifreeze"(**) mixes at all. A lot of the time they just use tap water and then the magnesium/calcium hard water components end up precipitating out and blocking rads up. If you can't get Diaqueen then the orange GM Dexcool coolant is a close (but not 100% identical - RTFM) replacement _as long as a full coolant flush is performed in-between types_ or you risk gelling Hint: If you're really stuck using tap water, BOIL IT, then let it cool for 12 hours in a tall container and decant off the top 2/3 through a fine filter. That will eliiminate most (but not all) of the problematic dissolved solids. When I lived in the Philippines people would use the same "distilled water" sold for drinking water (big industry there as the tapwater was generally unsafe to drink) in engines with no additives(**) - that's OK(ish) for a short period but hot deionised water will start dissolving every component in the water loop (ESPECIALLY aluminium parts) after a short period.. Rainwater is much the same as "distilled" for these purposes. It's _still_ better than most local tapwater especially if that water has any apprecial dH (degree of hardnbess) ,easurement All those different coolant types mean something but you can't rely on the colours - and mixing types may result in the coolant turning to jelly, so it matters a lot. This is why the only safe way to change coolants is a complete water flush in between (*) "Cheap green coolant" - usually bright green, usually Glycol with no other chemicals, usually contains some silica, EXTREMELY ABRASIVE on pumps and wherever the flow changes directions (**) Calling it antifreeze makes a lot of people in frost free environments think they don't need it, so _don't_ call it antifreeze
@gvet47 Yes, buying the correct bushing would in all likelihood be less expensive. But, if they are not available and the alternative is buying new rods, making the bushings will be a significant savings.
@@v8packard Alternatively, making them from a "close, but no cigar" part might be an option _if_ such a part exists The fun starts when someone realises there's a market void for such a part and fills it. Kubota(USA)'s reaction would be very telling Incidentally, "face"still matters a lot to Japanese makers. Calling them out publicly in ways that Japanese media/consumers can see for actions of their foreign subsidiaries is frequently a way of getting things fixed (and problematic American/European executives REMOVED)
The trouble with a lot of off shore manufacturing is quality control. They may start off with the initial set up being in spec then somehow something gets bumped or skewed and the entire production run is finished and out the door without being checked until guys like us run into a problem and realize somethng isn't right. I've run into situations like this myself over the years, the last one was on a power divider for an Eaton rear end, bushings for the spider gears, new ones were way looser than the old slightly worn ones, supplier said these were the only ones they could get so I started phoning around and found a couple other suppliers that had them, asked them to pull one off the shelf and measure one for me, well guess what, they were all wrong and the same so it was a whole production run. After several hours researching and phoning around I gave up and left the original ones in which were not perfect but still ok because I had a deadline to get it back together. Now about Kubota, I had a customer bring me an older tractor he took to the dealer with a severe engine knock, they told him they checked it out and wouldn't even bother going further because it had a broken crank and it needed a new engine and charged $600 for diagnosis. Not being able to afford a new engine he brought it to me for a second opinion and I just removed the head to have a look at things, everything looked great, no sign of a broken crank, just touched up the valves, replaced the injectors and pump which I figured were the issue and that was it, ran great. Had he left it with the dealer he would have ended up with an engine and huge bill he didn't need.
"The trouble with a lot of off shore manufacturing is quality control." The story of Toyota's work with BMW on the Z4/Supra is worth repeating Toyota were shocked and disgusted that BMW simply layered in parts where they'd fit with no consideration of later serviceability (Toyota Japan CAD the hell out of everything to ensure things can be serviced in place - if you find "serviceable" parts buried inaccessably on a Toyota, it wasn't designed in Japan - looking at YOU, Toyota USA - Toyota trucks in particular as they're not even built/sold in Japan) Toyota were even more shocked and disgusted to find that BMW simply tested parts for acceptance and then never looked at their compliance again. Toyota sample EVERY batch of components that comes in from external suppliers and reject entire batches if they dont meet spec. It keeps those suppliers honest Toyota also invented "just in time" manufacturing but the way that American makers have copied it makes them laugh up their sleeves. Toyota policy is to hold sufficient stock such that a disruption of supply chain (missed delivery, supplier factory fire) DOESN'T impact their prodoction ability. They actually _increased_ semiconductor buffer stock levels after the 2011 earthquake revealed a vulnerability to supplier ramp up periods which may exceed 4 months in the worst case scenario Far too much "american" emphasis is on saving a few cents by pushing risks off to supplers, whilst taking no account of what happens if those suppliers take a hit for any reason or if those suppliers might decide to try and make savings by making undocumented shortcuts I put "american" that way because it's not just a USA problem: In the NZ town I went to High School, one building contractor heavily publicly congratulated themselves (newspaper advertorials) on being able to save millions on construction costs of a local government office building project after a highly qualified quantity surveyor had identified massively overspecified building strengths that she was able to pare back. Fast forward a few months and the new City Public Library was the subject of controversy as it had been discovered that it could only hold books on the ground and first floor (of a 7 story dedicated building) due to "someone" having stripped out 80% of the reinforcenments needed for the building's floors to safely take the weight of bookshelves. The building contractor and quantity surveyor were notable by their absence from the fallout and during the ensuing litigation her name was suppressed by court order despite being all over the newspapers a year prior. The building should have been demolished but wasn't and it took 30 more years for the city to obtain a public library capable of housing all its book stacks on one site The same building contractor/quanity surveyor were in the news more recently when structural investigations at the local University uncovered that 6 large buildings they'd put up in the same period would come down like a deck of cards during any substantial earthquake - the area being 50 years overdue for an earthquake of that magnitude. The result has been the entire site cordoned off and 12,000 staff/students being forced to be rehoused elsewhere. Criminal prosecutions have been hampered by most of the people originally involved now being dead, suffering advanced dementia or living overseas and out of reach of extradition treaties
I don't know about the Kubota bushing but I would think you can adapt a bushing from a different application into the rod. Small ends can be bored. Bushings can be honed
I came here to ask the same question. The shop has a lathe now. Can't they buy slightly over size bushings and machine them to the correct size? That's what Jim did with the valve seats. He modified them for a perfect fit.
I'm sure that's going to be the last resort. If I was the customer, if the ole man says this is what he wants... He gets it! Every video shows just how much these 2 guys know and I'm smarter because of their videos.❤
Thanks for another great video on one of your rebuilds. You saved this customer a lot of money by rebuilding instead of a new motor. Thanks for doing that. Was another great teaching session by you Jim. Enjoyed following you along as you did the various steps on the rebuild. I learn more and more from each one of your videos.

Basically do what you did with the valve seats, get a oversized bushing and machine to fit, split it in 2 or machine a grove all the way around in the ID and OD for oiling
I feel for the Cleaning Guy having to explain about the lines in the cylinder. Long ago l used to be one of those a holes speculating and asking questions, sadly, that's what happens when you don't know any better. Thanks for taking the time to explain to the nay Sayers. 👌😎👍 You guys rock.
The problem isn't "not knowing any better", but not taking on board WHY such things exist and why they may not matter The real a'holes will keep on bleating about those lines after having had it explained that's it's a purely cosmetic issue
We use the little kubotas on pipe handling equipment in the oilfield, it would explain the dirt/dust, overheating issues. they get run for several hours a day with little to no maintenance by most companies
I overheated the D950 in my 1986 Kubota b7200, after a rad hose burst. It got pretty hot, but blowby isn't bad and it doesn't sound worse than it did before the overheat. Someday I'll get it rebuilt, with new dry liners, but I have to find a great machine shop first. I'd love to use JAMSI, but they're 700 miles from here.
I've had a Kubota motor start to overheat before. Turns out it was the loose nut behind the wheel... me. I caught it well before there was a problem, however. I just stopped the tractor and let it idle for a little while until it cooled itself. I was pulling a bush hog up a long hill. This was just too much to ask of the motor. It was a 34hp, 4 cylinder Kubota. I traded the tractor for a more powerful Kubota model. There are many Kubota motors out there, so I'm not surprised to see one in your shop. Mine have been very reliable. The wooly-faced kid is a well-educated, smart professional. He brings a wealth of knowledge to this channel and is a great asset. Keep going, Nic.
@happyjohn8256 Thanks for the reply! When I wanted to upgrade to a larger tractor, my very first choice was a John Deere 4 series. I like American stuff. However, none were available at the time, and the dealer would not honor the John Deere discount that was available. The same type of large discount was available from Kubota, and the local dealer had one. So I bought an L6060.
@@russellsmith3825 Thanks for the comment! I don't know beans about the cooling of Kubota vs. Yanmar. At least I think JD is using Yanmar for 4 series? Comments?
Dis you ever replace the fan or PM the water pump on that tractor? Did you find the radiator clogged up with dirt/leaves/grass/debris and required lots of cleaning...like once a day or more?
@JohnSmith-pl2bk No. I haven't. I don't use it for heavy agriculture. I do use it for making hay or bushhogging, and I haven't had such an experience. Good question! Thanks!

I'm 60 years old and had my foot in the car industry all my life - worked as a vintage car mechanic for Mercedes, Rolls-Royce and Bentley cars the last 10 years. I noticed a sharp decline in the industry around the new millennium, when globalization took a hold and factories moved to the east (China, etc.). The quality of parts today is questionable, be it from the factories it self or aftermarket. Parts with out of spec dimensions, poor material quality or incorrect hardening is common today. Manufacturers don't want they're products to be fixed, they want to sell new stuff. Keeping parts for the plethora of different models (and updates) they produce every year is unsustainable. Changing over to electric cars doesn't make the situation better... Even reproduced parts directly from Mercedes with a hefty price tag didn't fit without some modification and loose bushings is only a minor problem we faced...
You obviously never worked on British marques. They were always crap (as were european fords) and simply got worse after the 1950s. That's why when import restrictions were removed at the end of the 1960s, Japanese models simply steamrollered British ones in both Australia (land rover went from 98% of the 4wd market to 2% in 12 months) and New Zealand (All British models went from 65% of the market to 18% in 18 months whilst Japanese models went from 15% to 80% in the same period. American(canadian built) cars had already disappeared from the market, other European models stayed at 5% and the rest of the padding was Australian Holdens/Fords) - The only change was that Japanese cars were given the same import tariff that British/Australian/Canadian models got When all import tariffs were wiped in 1986 (prebuilt or kits), the only change was a slight increase in European car imports (German built Fords/Holdens started coming in as replacement for Australian-built Vectras or locally assembled Sierras), but most "euoprean" importers simply held prices and doubled their profit margins for "exclusivity" instead of trying to actually compete on build quality) When Ford tried to sell European-built models instead of rebadged Mazdas, they LOST business hand over fist - I recall seeing Grenadas, Mondeos, Fiestas and Kas sitting unsold for upwards of a year on my local dealer lot. Likewise, GM had trouble selling anything other than rebadged Isuzus and when they tried to sell their first shipment of Vectras as "Vauxhalls", not even sales reps would be seen dead in them. 998 of 1000 in that shipment had to be phsyically rebadged as Opels after sitting on lots for 12 months (at which point they all sold in 8 weeks. It was the Vauxhall badge which NZ consumers objected to) 1970s Rollers were just as bad as BL/Ford/GM - that's why the standard joke amongst RR owners was that you needed 3-4 in order to be sure to have one driveable at any given moment
@@miscbits6399 You're absolutely right - i never worked on dayly commuters...mostly worked on the european top dollar brands from the 1920s to the 1950s, with a fair share of British sports cars from the 1950s to 1970s... My comment was related to the parts situation for those cars.
During the late 1970s to early 80s, I worked for a local bus and coach company in South Eastern Queensland, Australia. I came to work after my Christmas break to find bus number 5 in pieces (this was an ex-Brisbane City Council Leyland bus and had done more than a million miles at a guess as no actual figures were available.) Russell had correctly diagnosed the problem, removed one head, and found a groove worn in the cylinder where a gudgeon pin had come loose. They purchased a piston and a sleeve and were about to put it back together. A gudgeon bush had come loose in the conrod little end and turned, cutting off the oil pressure to the pin, which flogged out. The first thing I said was, “If one has done this, what about the other five?” We dropped the engine out and checked it out. (Can only reach some of the 'Big ends' while in the chassis.) This sizeable 6-cylinder engine, 11lt 680ci, weighs one ton and lies on its side under the middle of the bus. I pushed out four of the other five bushes with my thumb so the problem would have reappeared within a few days or months. We had made for us, fitted oversized new bushes to the conrods, and put everything back together. I suggested, “We should start it before all the trouble of mounting it back into the chassis.” It ran for about ten seconds; there was a sound of breaking glass and much knocking. We removed a head and found the new sleeve had broken the land holding it at the top, and it had slipped into the bottom of the engine; oh, what a mess! Sometime in the engine's life, some dodgy work had been done, and the land groove was 0.006" too shallow for the new sleeve. Pays to check everything. Ted from down under.
Interesting on the pin bushings. I think you are right, they are loose so I can put things together in the field, and in frame, which makes me happy and the manufacture happy because I'm not complaining I had to beat the pin in and now it's stuck or the rod is bound up. It'll work for awhile.
I hope Jim’s son reads this. I couldn’t imagine the channel without you. I love the father son dynamic. I wish I had a relationship like that with my dad. We don’t. Never will. I love watching you two work together and the videos in general are made very very very well!
Probably 30 years ago I took not a diesel, But a gasoline engine apart and the first 2 bores were worn out way oversized compared to the second 2 and a machine shop explained to me. They figured out. It was poor coolant flow because the water pumps were really under sized for that engine. And that is the hottest part of the engine going back through the water pump to thermostat housing.
What I like about this channel is the knowledge you guys share and the father and dad aspect. I think that is great to see a son wanting to learn and follow his dad. Dad is a great teacher and has a huge amount of knowledge. Great channel
I am no machinist but understand what you are doing to these engines. Pay no attention to the keyboard warriors. Keep the hairy cameraman handy and keep posting the great videos.
I own an independent diesel repair shop in Texas and we just don’t have any good and trustworthy machine shops near us anymore and therefore we refuse to do engine rebuilds in house anymore because the quality is just not there nowadays causing independent shops to refuse to do anything other than quoting customers full replacement because of the liability we carry and the machine shops never stand behind their work. I love seeing how thorough you guys are and wish you were more accessible to us because you are men of integrity, honesty and that’s sadly a rare attribute in the repair industry anymore.
I'm a bit surprised you haven't pulled the freeze plugs to check for scale build up on the cylinders. From the brief looks down the cooling passages, it does look like there's more than I'd allow to stay. Maybe boiling the block is in order. Given how hot the rods got, do you run a cleaning wire through the lubrication hole, rod journal through to the the top of the rod, to clean out any baked oil?
Not only is it extremely satisfying seeing you rebuild these old motors but you guys do it with such a pleasant style and approach. And the fact it’s father son is the best part. Keep doing you. Screw the haters.
Great job guys! Always doing great work. Have had brunt boots for 3-4 months now and are definitely the most comfortable boots I have ever worn. Even out of the box. Great product!
If you're running a Kubota in your Bobcat you need a Donaldson cyclonic clear bowl pre filter on the intake. I'd tip a cup full of fine dust out of mine after four hours work that would have otherwise made it into the paper air filters.
"You are the only one to complain" I hear that sentence -everywhere. They want to make You feel bad, question Yourself, maybe the error is on Your side. This tactic is so widespread… Even my landlord: the heating is messed up, I´m freezing at night. I ask about it:"You´re the only one to complain". Then they drag it out until You say "Fuck it" and go the expensive route. Customers can be glad Y´all do all the measuring and checking. So: Cleaning Guy, Wooly Mammoth: Don´t You ever change. Kind Regards
I love this channel! As someone that has a relatively small machine shop at home, I love seeing you guys use these extremely precise machines for actual work and seeing the expertise the cleaning guy has is just incredible! Never stop making these as long as y'all can, ❤️ JAMSI
I wish we had a machine shop in San Antonio Texas with as much care as you guys have. Y'all care about the customer first, great job. Leave the wooly man alone, it takes two machinists double checking every process to get it right.
Mate, grew up using inches and then flipped to metric in 1970's. Metric for most things is just plain easy. For "thou" you are metric anyway! As usual, absolutely LOVE these sessions!
The real irony is that somebody would take time out of their day worrying about the units that measuring tools are graduated in to achieve the same exact result. The only downfall of the tools he is using is that he would need a calculator to figure out how many pistons stacked side by side would cover an acre LOL. Or how many would stack neatly inside a 5 gallon bucket.
Thou is thousands of an inch. You meant decimal. Just cause Metric is based on Base-10 math, doesn't mean you can call subdivisions of imperial "metric."
@@kstricl I have worked with a lot of guys older then myself in a shop that was metric because we worked on two basic parts for General Motors that were dimension in Metric. The reamed holes had +-.0125mm tolerance tho LOL. But John the one Inspector would come running in with his hair on fire "HEY THESE HOLES ARE FIVE THOUSANCE OVERSIZE"...we would have to remind him "John, those are Microns, and it is aluminum part that is 125F fresh out of the wash cycle"...and he would sheepishly say "Oh, yea...LOL".
We had a load back in the early 00s on the 3 cylinder in arcgen welder generators. The radiator was too small and often got blocked. Was always cylinder no 2. We done 10 of them over 2 years in Scotland.
i had the reverse on cam bearings on a 55 allis chalmers. the aftermarket cam bearings were .005 too small and the manufacturer argued with me on the sizing. i found a new old stock at a local shop that used to sell parts and he had the correct bearings and the cam slid right in and is now running for 5 years. aftermarket seller would not give me my money back on product. don’t use them anymore
I try not to read the comments because they cause cancer, but I'm shocked that some said to get rid of your son on these videos. I find you and your son to have excellent chemistry and make for extremely interesting videos using tools I'll never be able to own. Please keep doing what you're doing. This is excellent stuff.

I went through this on a V3007 (Cat C3.3B) in a Cat 906H loader. Overheated, combination of terrible radiator placement and operator. Scored the front cylinder the worst. 8k hours, the rest of the engine looked new yet. Bored .5mm over, got pistons from Cat. 1.5 years later they cooked it again, this time it took sleeves as no larger pistons are available. The Chinese overhaul kits off Ebay are actually pretty good quality. Cracked the head as well. I added a Murphy switch to hopefully protect it now.
Hi from Sweden. Its not that long ago that inches where used by house builders and carpenters here. My late father, born 49, a timmerman (timber man, more like heavy carpenter) always used inches. It was 2 inch 4 etc for timber and 3 inch nails etc. Contradictory though he measured the timber in metric 😂. The folding rulers used to have both millimeters and inches on them but that's quite rare know. Most people still call them "tumstock" (inch ruler) though. I do think it's easier to learn metric from the beginning but when you've learnt it you know it. Keep up the good work.
@@racerich888He can and probably will, but its not just as cut and dry as that, there are many many types of brass and bronze alloys, all with differing characteristics, it cannot be garunteed a reproduction can match the factory design.
@racerich888 Well that's the only complication isn't it, how would he find that out by certainty. Some of them as you have seen have a chemical coating, why would he incur the risk of having the engine fail due to his bushing when they are cheap enough to get OEM ones and wait..
Crazy how bad the upper end was and the crank took so little to het back into shape! BTW I've wrenched on engines for a living for years and the wooly faced kid has taught me so much I didn't know having never been on this side of the rebuilding process. And he did it all through YT! 👏🏼
I work for VW and were running in to similar issues with cylinder heads. Exhaust valve guide seals are literally popping off of the guides. The max. Movement of the valve in the guide should be .8mm, I’m seeing heads measuring 1.2, 1.3 with only 40k miles on them. Then we get a brand new head, not even a reman and the clearance is at .8mm from the factory. Just unacceptable workmanship.
To answer your question if other technicians are receiving parts that simply don't fit like they are supposed to. Yes I receive parts that are not correct regularly. My workplace is a Linde lift truck dealership and linde does a fairly good job at quality control but when dealing with other brands of truck I have alot of fitment issues or changes to components that require completely different hardware in order to use.
What about machining ur own bushings in that new lathe ? Or machining an undersized set? I have no idea what material or treating process it would need or if it would be far too time consuming.
Of COURSE they're gonna tell you that you're the only one that has reported the problem with those pin bushings! You didn't think that they would be honest, do you?
My experience with Kubota is the reverse airflow. The cooling fan draws air from the engine area, blowing out through the rear of the radiator. Dirty jobs such as mowing plug the side screens and then it gets hot. It happens very quickly (minutes in hot weather) I noticed this and kept a brush handy and when the screens are plugged and heat begins to spike, I stop and brush it off. Proper cooling is the life of the engine.
Check the weep hole in the water pump. I had been having coolant loss in an old IH TD15 that I couldn’t track down cause the water pump is buried way down inside the machine. The bearings finally left the building so after the pump was out you could clearly see it had been leaking for a long time. So yeah - check that pump.
you guys are great. lots of hard work and dedication here, not to mention technical knowledge. Don't pay any attention to the negative comments, fixing that boat anchor is not for the novice internet critic.
ya we had to eat a 20k motor from them we needed the loader back asap no parts around during covid. ours had cracked head. bad injectors can cause that also.
I have seen a lot of the short videos This is my first full video It’s great seeing a son follow in his father’s footsteps and a father teaching his son the trade
I know from experience that a lot of the smaller Kubota tractors have really weak fan blades, plastic that are easily prone to damage, too many people don't notice or don't care to fix it
The machine you did all the valve seats and guides im a little curious how the table moves so easy. The only thing i can think of how it works is air hockey. Am i close?

I'm gonna say it, Metric? State of Alabama went Metric in the 60s on account of the Space Race. Some areas of the state you can still find speed limit signs in KPM and road signs in Kilometers, as well as International Road Signs. So, in 2nd grade in 68/69 school year our teacher Miss. Jackson taught us both Fractional SAE and Decimal Metric measurements.... Which still tickles me and makes me laugh for so many more reasons and why I have some weird nightmares.
@@Mike-bm6cf oh, I understand this question thanks to being in the Navy for a life time and going everyplace. Believe it or Not! You can tell where you are by the shape of the foot, or where your great-greats came from. Over all the American Foot is truly an American Foot and it reflects our Mixing Bowl Heritage. Over all it has a thin heel but wide forefoot area, and this is unique to the US and makes finding shoes an issue. Only New Balance uses a last (the form the shoe is constructed on) that fits American Feet the best. If the shape of the foot overall is wide from forefoot to heel, look to England and the British Isles for large shoes that are like bricks, small sizes but still wide South East Asia, Skinny small sizes Italy and the Northern Mediterranean area, Long and Skinny Africa. But for the most part, if you CAN find a US Maker of Shoes where they actually DO make the shoes on US Soil they should be making a shoe to fit you. If its made in China (number 1 maker of US brands) you'll find they make shoes to fit their own feet....which is why most brands you find lack large sizes and wide sizes. The maker simply does not believe us American Giants really exist ...well, not until we step on their toes with our great big feet.

@@geneard639 Its unusual, the USA have a decimal currency but imperial measurement system, okay it's historical but it followed the old UK measurement system, the only thing is the UK moved to decimal systems for both money and measurement back in the 70s. As with all systems the more complex they are the more likely errors will be made. As for using both systems at once, need I say more than the space shuttle mirrors.
Of course free choice is important but at the expense of making costly errors, it wouldn't be my choice.

I remember a machine shop that I used to deal with had an engine that they couldn't find the pin bushings for it without waiting for weeks. His solution was to buy bronze bushings that he machined the OD to size and trimmed them to length. Then he pressed them into the rods and bored and honed the ID to custom fit the pins. Even with the extra work, he came out cheaper and faster than waiting for the parts from his supplier.
Yes, I have known of examples like that. I worked briefly back in the early eighties for a company that produced envelopes. On one of their machines there was a grinding noise in the drive gearbox, and it turned out to be a defective shaft that was out of specs. Well, the machine was under warranty and after some back and forth with the manufacturer it was decided to wait for a replacement shaft. This amounted to water under the bridge and a machine that was down and could not be used thereby causing production to stop (there were other machines, but it still affected production). The company would have been better off to have made a new shaft (they did have a machine shop) but of course they wanted to exercise their warranty. Of course, by exercising their warranty they lost more than they gained. Sometimes it pays to go ahead and attack the problem with your own solution.
I trained in power stations leaving in late 1980s. We regularly had shafts and bushings made locally at a small fraction of OEM cost. Warranty was irrelevant of course.
@@billywird you've made a valid point and I would probably have done the same, but they might have refused to tamper with a machine under warranty because the manufacturer could refuse to assume that warranty later if something else went wrong and they found an unauthorized repair / non OEM part.
If not for that reason, then that's a bad decision on their side.
@@pbe6965 Yes I realize that management had to consider that as well.
You can not use full bronze bushings in the piston pins. OEM connecting rod pin bushings are made of steel with a fine layer of bronze in the inside, so they are stronger. Full bronze thick bushings are soft and they will compress with time and will increase its clearance, and later end in catastrophic failure to the engine. Never install full bronze bushings, only steel backed bushings with inside bronze layer can be used, as the OEM ones are made.

About a year ago I cancelled cable and now just have an internet connection. I’ll watch this father son team any day over the junk they have on TV these days.

It’s the son thats producing and directing this channel. Thank you to the both of you!
One old guy to another, I'm with you! I cancelled cable in 2001and have not regretted it one bit. Course they nail me now for one gig is more than I used to pay for cable but I choose what to watch. I would love for this shop to do all my machine work. The depth of their detail is second to none, as is their business ethic. New subscriber and look forward to future episodes.

I used to fix electronic equipment in a hospital. It was amazing how many times we would encounter a problem and be told by the manufacturer we were the only ones having this problem. Once the manager phoned another hospital halfway across the country with the same equipment to see if we really were the only ones having this particular problem. They had been told the same thing by the manufacturer that we were told. We had to get health Canada involved to force them under threat of federal lawsuit before they admitted they knew about the problem all along and agreed to fix it.
This is so typical. Have had this experience in a number of cases.
Lol right, we can play the same game against them they are playing

The chemistry between you both is what makes the videos so good, the people saying that it should only be one of you definitely don’t know a good thing when they see it.
Being an ex automotive machinist my self .I am all aways impressed with the qualty of your work .
When I retired 20 years ago manufactures an supplier's told me the same crap.Never had that happened before tells me it's time to find another supplier. Great video you two.
The one exception I have to that rule is if I hear "you're the first - and we need to figure out why this has happened to make sure it doesn't happen again"
On the other side of it as a supplier (ISP) I've had to say to a customer "Something obviously changed if it was working yesterday - and if I had changed anything I'd have my phone ringing off the hook. I need you to think really carefully about what might have been altered on your system so we can both solve this issue" - at which point they'd remember a windows update or new piece of software installed on the system
I've heard similar stories about "nothing changed" in mechanical stuff which involved an oil change and cheap taiwanese(*) filter which turned out to be full of debris (or in another case an "oil flush" after decades of no oil changes which upon engine autopsy was found to have dislodged accumulated gunk that found its way into critical galleys and blocked them entirely
(*) It was the 80s - when "made in Taiwan" was taking off, "made in Japan" had long-transitioned to being consistently high quality, "made in China" was still in the future, "made in the USA" was a crapshoot for quality - some was still good and some was VERY VERY bad - "made in Britain" was generally regarded as "put it back on the shelf and pretend you never saw it. Better yet, sweep it into the garbage bin" and "Made in Germany" meant "high quality but utterly unaffordable"
It's interesting how critical folks can be of your tools and work processes from the perch of their couch or easy chair. I like to take care of my tools as much as the next man but in a successful operation like yours for example, I applause you both for staying on task and doing nice work for your customers. It's as clear as the nose on your faces to me that you are both doing a fantastic job.
Tbf it is easy to get a piece of metal to come off and get embedded in your skin. My grandfather has a piece of iron in his finger to this day from a similar worn down tool. It doesn't seem to bother him much, but if I had a choice between getting iron shards in my hands or not, I would prefer to remain shard free.
@SchwachsinnProduzent I understand how unpleasant that can be. I find metal fragments in my skin fairly regularly. It's just an occupational Hazzard. It's still a good practice to clean up your punches chisels and drivers to prevent those mishaps.
I wish your shop was in my area! I spent a couple of years working as an automotive machinist, back in the early 1980s. And I'm very impressed by the quality of your work and the standard of customer service you show. I just don't see that in the one local shop we still have. And I hate admitting it, but it's the shop that I worked in.
It’s a shame when a brand goes from being known for quality to building disposable products. I love that you are willing to accept the challenge of fixing something that others wouldn’t touch, take the time and go the extra miles to make it right.
Kubota are not disposable..
Dealership just didn't want to rebuild it because labor to high .
They just want to sell new machines.
Surely if they do not want to repair an item and the only option is to buy a new one, that makes the item disposable, in this case a disposable Kubota engine.
Same old greed play from big corporations be it Apple, John Deer, Chrysler or Ford. The parts, subassemblies and or services are priced to prevent repair and to drive all independent repair shops out of the market. E. G. A broken charge chip on an Apple computer, manufacturing chip cost 60 cents retail. Apple refuses supply the chip to independents or allow the manufacturer to sell it to anyone else. The Apple solution is $1700 for a replacement motherboard or $1750 for a new laptop. In this case the laptop surely becomes disposable.
@isoguy. We rebuild all those engines ?🤔
@MitzvosGolem1 That's really good news in a throw away world.
@isoguy. many things are I agree
I used to work in a military machine shop as a civilian contractor and we used to get hercules 4 and 6 cylinder diesels to rebuild that had been sitting in a "Can Point" for decades buried in the dirt. Almost all of them had pistons that looked just like those Kabota's. We cleaned them up, used old rings as groove cleaners, spun the pistons on a lathe to smooth out the rough spots, and put them together. They made dyno numbers and held together every time! Low RPM engines don't need as much precision.
I pulled a 3TNV76 out of a "John Deere" tractor last year and had a local machine shop go through it. I bought all the aftermarket (Chinesium) parts for it, rods, pistons, piston pins, rings, bearings, gaskets and head and everything actually went together within spec which shocked me. 1 cylinder had to be sleeved due to a pin retainer coming out and putting a deep score in the cylinder. The price difference between the aftermarket parts vs factory Yanmar was ridiculously high. It would have been 2.5 to 3 times higher for the factory parts. Any time I do work for someone (I'm retired) I charge them a little something for my time chasing parts or on the phone or computer trying to round up parts. Time is money, especially if you're driving around going to the machine shop or local parts stores, gasoline isn't free...
Yes I had a friend of mine who charged for the rounding up of parts and going to suppliers and getting stuff (the errands that folks expect to come with the cost of the job). I did the same thing when I was a RPS P&D Contractor and owned my own package truck. I did work for other contractors and figured in my time running parts and such to do the repair work on their package trucks. As we had to provide a vehicle and driver as per our contract, I could do regular jobs like brake jobs and clutches and even other work that could be done over the weekends. This enabled a contractor to not have to rent a vehicle while his was tie up in a repair shop and was well worth the extra money spent with me. I also patched and repaired many items due to the fact that the package truck would be down waiting for parts.
We had a 4 cylinder Chevy car. At 15000 miles it needed a new exhaust system. We took it to a muffler shop. They didn't have the exhaust manifold which was just header pipe . Down in the middle of where the four pipes came together it rusted out because the heating from welding it caused it to rust fast. They called my wife to tell her they didn't have the part. She went to the Chevy stealership and they had one, $250 . This was around 1990. She asked why it was so much. The guy proudly said , " Because it's an original GM part" . When she told me I said, " Did you tell him the rusted out one with 15000 also was an original GM part. "
I drive a Fiat 1.3 diesel which was a Fiat & GM joint project. The only problems are stuff done to suit GM. The cam chain is a real pain to work on and lasts no longer than a cam belt. A Fiat cam belt would have made it one of the best engines ever.
Hi there from Australia,,, Diesel Fitter here,,, I was taught, if the piston grabs at the ring or above, its a coolant problem and if it grabs below the rings its a an lubrication problem,,,, love your vids ,,
Based on the damage I'd bet on that engine getting dusted, not so much a coolant issue. Coolant issue should have cooked the middle cyl not 1 then 2. Might even be bad injector made number 1 wash the cylinder then overheat residual thru cylinder wall overlap.
probably others have said this often - but the shop organization and cleanliness (like a kitchen - some are like new - others greasy and worn looking) - is truly impressive and a strong indcator of work standards being high.
I am appreciative of the skills, personalities, work and good looks of both the stars of this show.
For me , I’m an auto mechanic.
Will be an honor having my Dad working with me on the shop

I haven’t watched a video of yours for a long time and as for your son, he has matured tremendously is very knowledgeable.

I'm not a pro but I have learned a few tricks, this would require more machining but will get the job done & with the correct tolerances. 1- are there any business that do Industrial Hard Chrome Plating ?
If you can't get the correct size bushings you could get the wrist pins built up with chrome but would have to re-bore the pistons to accept the bigger diameter wrist pin, and probably have to rework the wrist pin clip groove and maybe even larger.
When I lived in Connecticut, I got involved in oval track racing, the owner / driver of the car owned an Industrial Chrome Shop, we would chrome our rocker arm shafts, crank journals ect., I hope you find what you need but you asked for suggestions, I hope I may have opened up a new avenue, love the videos, you guys ROCK !
How much does chroming cost vs the life extension/maintenance reduction benefit
I get it matters in extreme load situations but does it matter in low load ones?
My immediate worry about those blued bushings isn't about the sizing of replacements but about oil flow inside the rods or if squirters are needed. Ideally you don't want to ever see the engine come back with a simliar complaint
The cleaning guy and woolly faced youth are both correct in wanting to see a failed engine in-situ to locate and correct the underlaying causes
We love the wooly-faced kid, he has all the new ideas to buy new equipment. LOL
Working in the industry that use primarily Kubota engines (grounds machinery) the radiator is usually the cause being blocked up with dirt and grass clippings. The water pumps fail regularly too. Great video, I've been inside so many of those engines.
What PM change interval would you recommend re water pump replacement (X 1000 hours)?
And the coolant...any recommendation?
@@JohnSmith-pl2bk, change the coolant at 5 years, water pump when it fails..... or when you want.
Used to do a lot of work on my Kubota and learned real fast to keep the radiator clean when mowing! Got it a little hot and at the end of the day when I idled it down the oil light came on because of the temperature. After cleaning the radiator the temperature came down and it was fine. Guess I caught it in time!!
@@garybulwinkle82 my grasshopper is terrible for the radiator getting clogged fast. in the summer its a habit of looking at that temp gauge all the time or at so many laps in the yard
Water pump failures are virtually always a result of "wrong coolant" or ""mixed coolants"
Clogged up rad externals aren't usually THE failure cause but a symptom of the same "don't care" operator attitude that has destroyed engine internals
Coolant isn't coolant isn't coolant - and the types used absolutely do matter (think: Electrolytic activity due to dissimilar metals. Most good coolants have chemicals added to minimise the damage from this)
A lot of coolant issues in small engines are because almost all Japanese engines sold since the 1990s are designed to use Diaqueen (the same light blue near-transparent coolant found in most Japanese cars) but people just shove any old cheap green stuff in there(*) - if they bother using "antifreeze"(**) mixes at all. A lot of the time they just use tap water and then the magnesium/calcium hard water components end up precipitating out and blocking rads up.
If you can't get Diaqueen then the orange GM Dexcool coolant is a close (but not 100% identical - RTFM) replacement _as long as a full coolant flush is performed in-between types_ or you risk gelling
Hint: If you're really stuck using tap water, BOIL IT, then let it cool for 12 hours in a tall container and decant off the top 2/3 through a fine filter. That will eliiminate most (but not all) of the problematic dissolved solids.
When I lived in the Philippines people would use the same "distilled water" sold for drinking water (big industry there as the tapwater was generally unsafe to drink) in engines with no additives(**) - that's OK(ish) for a short period but hot deionised water will start dissolving every component in the water loop (ESPECIALLY aluminium parts) after a short period.. Rainwater is much the same as "distilled" for these purposes. It's _still_ better than most local tapwater especially if that water has any apprecial dH (degree of hardnbess) ,easurement
All those different coolant types mean something but you can't rely on the colours - and mixing types may result in the coolant turning to jelly, so it matters a lot. This is why the only safe way to change coolants is a complete water flush in between
(*) "Cheap green coolant" - usually bright green, usually Glycol with no other chemicals, usually contains some silica, EXTREMELY ABRASIVE on pumps and wherever the flow changes directions
(**) Calling it antifreeze makes a lot of people in frost free environments think they don't need it, so _don't_ call it antifreeze
I will sometimes look for pin bushings sized closer to what is needed, but most times anymore I just make them from 954 bronze.
exactly what i was thinking they have a lathe
Even though this is just four making your own parts will add to the rebuild, will it not?
@gvet47 Yes, buying the correct bushing would in all likelihood be less expensive. But, if they are not available and the alternative is buying new rods, making the bushings will be a significant savings.
@@v8packard Alternatively, making them from a "close, but no cigar" part might be an option _if_ such a part exists
The fun starts when someone realises there's a market void for such a part and fills it. Kubota(USA)'s reaction would be very telling
Incidentally, "face"still matters a lot to Japanese makers.
Calling them out publicly in ways that Japanese media/consumers can see for actions of their foreign subsidiaries is frequently a way of getting things fixed (and problematic American/European executives REMOVED)
The trouble with a lot of off shore manufacturing is quality control. They may start off with the initial set up being in spec then somehow something gets bumped or skewed and the entire production run is finished and out the door without being checked until guys like us run into a problem and realize somethng isn't right. I've run into situations like this myself over the years, the last one was on a power divider for an Eaton rear end, bushings for the spider gears, new ones were way looser than the old slightly worn ones, supplier said these were the only ones they could get so I started phoning around and found a couple other suppliers that had them, asked them to pull one off the shelf and measure one for me, well guess what, they were all wrong and the same so it was a whole production run. After several hours researching and phoning around I gave up and left the original ones in which were not perfect but still ok because I had a deadline to get it back together.
Now about Kubota, I had a customer bring me an older tractor he took to the dealer with a severe engine knock, they told him they checked it out and wouldn't even bother going further because it had a broken crank and it needed a new engine and charged $600 for diagnosis. Not being able to afford a new engine he brought it to me for a second opinion and I just removed the head to have a look at things, everything looked great, no sign of a broken crank, just touched up the valves, replaced the injectors and pump which I figured were the issue and that was it, ran great. Had he left it with the dealer he would have ended up with an engine and huge bill he didn't need.
"The trouble with a lot of off shore manufacturing is quality control."
The story of Toyota's work with BMW on the Z4/Supra is worth repeating
Toyota were shocked and disgusted that BMW simply layered in parts where they'd fit with no consideration of later serviceability (Toyota Japan CAD the hell out of everything to ensure things can be serviced in place - if you find "serviceable" parts buried inaccessably on a Toyota, it wasn't designed in Japan - looking at YOU, Toyota USA - Toyota trucks in particular as they're not even built/sold in Japan)
Toyota were even more shocked and disgusted to find that BMW simply tested parts for acceptance and then never looked at their compliance again. Toyota sample EVERY batch of components that comes in from external suppliers and reject entire batches if they dont meet spec. It keeps those suppliers honest
Toyota also invented "just in time" manufacturing but the way that American makers have copied it makes them laugh up their sleeves. Toyota policy is to hold sufficient stock such that a disruption of supply chain (missed delivery, supplier factory fire) DOESN'T impact their prodoction ability. They actually _increased_ semiconductor buffer stock levels after the 2011 earthquake revealed a vulnerability to supplier ramp up periods which may exceed 4 months in the worst case scenario
Far too much "american" emphasis is on saving a few cents by pushing risks off to supplers, whilst taking no account of what happens if those suppliers take a hit for any reason or if those suppliers might decide to try and make savings by making undocumented shortcuts
I put "american" that way because it's not just a USA problem: In the NZ town I went to High School, one building contractor heavily publicly congratulated themselves (newspaper advertorials) on being able to save millions on construction costs of a local government office building project after a highly qualified quantity surveyor had identified massively overspecified building strengths that she was able to pare back. Fast forward a few months and the new City Public Library was the subject of controversy as it had been discovered that it could only hold books on the ground and first floor (of a 7 story dedicated building) due to "someone" having stripped out 80% of the reinforcenments needed for the building's floors to safely take the weight of bookshelves.
The building contractor and quantity surveyor were notable by their absence from the fallout and during the ensuing litigation her name was suppressed by court order despite being all over the newspapers a year prior. The building should have been demolished but wasn't and it took 30 more years for the city to obtain a public library capable of housing all its book stacks on one site
The same building contractor/quanity surveyor were in the news more recently when structural investigations at the local University uncovered that 6 large buildings they'd put up in the same period would come down like a deck of cards during any substantial earthquake - the area being 50 years overdue for an earthquake of that magnitude. The result has been the entire site cordoned off and 12,000 staff/students being forced to be rehoused elsewhere. Criminal prosecutions have been hampered by most of the people originally involved now being dead, suffering advanced dementia or living overseas and out of reach of extradition treaties
I don't know about the Kubota bushing but I would think you can adapt a bushing from a different application into the rod. Small ends can be bored. Bushings can be honed
I came here to ask the same question. The shop has a lathe now. Can't they buy slightly over size bushings and machine them to the correct size? That's what Jim did with the valve seats. He modified them for a perfect fit.
I'm sure that's going to be the last resort. If I was the customer, if the ole man says this is what he wants... He gets it! Every video shows just how much these 2 guys know and I'm smarter because of their videos.❤
Thanks for another great video on one of your rebuilds.
You saved this customer a lot of money by rebuilding instead of a new motor.
Thanks for doing that.
Was another great teaching session by you Jim. Enjoyed following you along as you did the various steps on the rebuild. I learn more and more from each one of your videos.
Appreciate your comment Jim about inches versus metric. You are like me , we grew up in the inches environment not metric. I still struggle with the metric system.
Thanks again for a great teaching session. Appreciated.

Why do people make comments like ‘the woolly face kid etc…?’ It’s rude and clearly disrespectful to these two guys who are doing this free and for our entertainment. It just baffles me. Great vlog as always guys 👍🇬🇧👏
Trump started the name-calling,must be infectious.
Its really nice to watch a video of professionals taking the time to do it correctly and not rip off people....also to have an entire shop clean, organized and filled with the proper machinery to get the job done and be HONEST TO THER CRAFT AND CUSTOMERS.... and yes the dirty shops, with dirt floors and back yard, junk packed shops in the country side and in the cities are rip off's....especially the 3rd world country foreigns who open shop in the US. Thank you you guys for doing it the right way as manufacturers require and be honest. Im a new subscriber from GUAM, USA in the southwestern pacific islands and part of the Mariana's Island Chain.
You guys, don't let no one-stop you from doing what you do. You guys are great. I love watching you guys because your family and family always makes the best business when they get along. I know that probably there's not always been that best of times but you guys seem to get along great... I hope that you guys live on forever. Because I enjoy watching you. No criticism here. Why would there be? I'm not pretending to be someone I'm not. I'm not a keyboard warrior
Basically do what you did with the valve seats, get a oversized bushing and machine to fit, split it in 2 or machine a grove all the way around in the ID and OD for oiling
I feel for the Cleaning Guy having to explain about the lines in the cylinder.
Long ago l used to be one of those a holes speculating and asking questions, sadly, that's what happens when you don't know any better.
Thanks for taking the time to explain to the nay Sayers. 👌😎👍
You guys rock.
The problem isn't "not knowing any better", but not taking on board WHY such things exist and why they may not matter
The real a'holes will keep on bleating about those lines after having had it explained that's it's a purely cosmetic issue
We use the little kubotas on pipe handling equipment in the oilfield, it would explain the dirt/dust, overheating issues. they get run for several hours a day with little to no maintenance by most companies
I overheated the D950 in my 1986 Kubota b7200, after a rad hose burst. It got pretty hot, but blowby isn't bad and it doesn't sound worse than it did before the overheat. Someday I'll get it rebuilt, with new dry liners, but I have to find a great machine shop first. I'd love to use JAMSI, but they're 700 miles from here.
That's a day in your pickup to deliver it...and a day driving back home again.
Got relatives nearby to stay overnight? Motel? Hotel? Camper?
@@JohnSmith-pl2bk 12 pack of Red Bull and go non stop.
I've had a Kubota motor start to overheat before. Turns out it was the loose nut behind the wheel... me. I caught it well before there was a problem, however. I just stopped the tractor and let it idle for a little while until it cooled itself. I was pulling a bush hog up a long hill. This was just too much to ask of the motor. It was a 34hp, 4 cylinder Kubota. I traded the tractor for a more powerful Kubota model. There are many Kubota motors out there, so I'm not surprised to see one in your shop. Mine have been very reliable.
The wooly-faced kid is a well-educated, smart professional. He brings a wealth of knowledge to this channel and is a great asset. Keep going, Nic.
@happyjohn8256 Thanks for the reply! When I wanted to upgrade to a larger tractor, my very first choice was a John Deere 4 series. I like American stuff. However, none were available at the time, and the dealer would not honor the John Deere discount that was available. The same type of large discount was available from Kubota, and the local dealer had one. So I bought an L6060.
Kubota cooling systems are undersized, with no wiggle room for error or dirt.
@@russellsmith3825 Thanks for the comment! I don't know beans about the cooling of Kubota vs. Yanmar. At least I think JD is using Yanmar for 4 series? Comments?
Dis you ever replace the fan or PM the water pump on that tractor?
Did you find the radiator clogged up with dirt/leaves/grass/debris and required lots of cleaning...like once a day or more?
@JohnSmith-pl2bk No. I haven't. I don't use it for heavy agriculture. I do use it for making hay or bushhogging, and I haven't had such an experience. Good question! Thanks!
I think the wooly faced kid and the cleaning guy do excellent work! As a matter of fact I know they do because I do very similar work. Looks great guys.
The chemistry you two have make these videos what they are. So keep making them together.
I'm 60 years old and had my foot in the car industry all my life - worked as a vintage car mechanic for Mercedes, Rolls-Royce and Bentley cars the last 10 years.
I noticed a sharp decline in the industry around the new millennium, when globalization took a hold and factories moved to the east (China, etc.).
The quality of parts today is questionable, be it from the factories it self or aftermarket.
Parts with out of spec dimensions, poor material quality or incorrect hardening is common today. Manufacturers don't want they're products to be fixed, they want to sell new stuff. Keeping parts for the plethora of different models (and updates) they produce every year is unsustainable. Changing over to electric cars doesn't make the situation better...
Even reproduced parts directly from Mercedes with a hefty price tag didn't fit without some modification and loose bushings is only a minor problem we faced...
You obviously never worked on British marques. They were always crap (as were european fords) and simply got worse after the 1950s.
That's why when import restrictions were removed at the end of the 1960s, Japanese models simply steamrollered British ones in both Australia (land rover went from 98% of the 4wd market to 2% in 12 months) and New Zealand (All British models went from 65% of the market to 18% in 18 months whilst Japanese models went from 15% to 80% in the same period. American(canadian built) cars had already disappeared from the market, other European models stayed at 5% and the rest of the padding was Australian Holdens/Fords) - The only change was that Japanese cars were given the same import tariff that British/Australian/Canadian models got
When all import tariffs were wiped in 1986 (prebuilt or kits), the only change was a slight increase in European car imports (German built Fords/Holdens started coming in as replacement for Australian-built Vectras or locally assembled Sierras), but most "euoprean" importers simply held prices and doubled their profit margins for "exclusivity" instead of trying to actually compete on build quality)
When Ford tried to sell European-built models instead of rebadged Mazdas, they LOST business hand over fist - I recall seeing Grenadas, Mondeos, Fiestas and Kas sitting unsold for upwards of a year on my local dealer lot. Likewise, GM had trouble selling anything other than rebadged Isuzus and when they tried to sell their first shipment of Vectras as "Vauxhalls", not even sales reps would be seen dead in them. 998 of 1000 in that shipment had to be phsyically rebadged as Opels after sitting on lots for 12 months (at which point they all sold in 8 weeks. It was the Vauxhall badge which NZ consumers objected to)
1970s Rollers were just as bad as BL/Ford/GM - that's why the standard joke amongst RR owners was that you needed 3-4 in order to be sure to have one driveable at any given moment
@@miscbits6399 You're absolutely right - i never worked on dayly commuters...mostly worked on the european top dollar brands from the 1920s to the 1950s, with a fair share of British sports cars from the 1950s to 1970s...
My comment was related to the parts situation for those cars.
During the late 1970s to early 80s, I worked for a local bus and coach company in South Eastern Queensland, Australia. I came to work after my Christmas break to find bus number 5 in pieces (this was an ex-Brisbane City Council Leyland bus and had done more than a million miles at a guess as no actual figures were available.) Russell had correctly diagnosed the problem, removed one head, and found a groove worn in the cylinder where a gudgeon pin had come loose. They purchased a piston and a sleeve and were about to put it back together. A gudgeon bush had come loose in the conrod little end and turned, cutting off the oil pressure to the pin, which flogged out.
The first thing I said was, “If one has done this, what about the other five?” We dropped the engine out and checked it out. (Can only reach some of the 'Big ends' while in the chassis.) This sizeable 6-cylinder engine, 11lt 680ci, weighs one ton and lies on its side under the middle of the bus. I pushed out four of the other five bushes with my thumb so the problem would have reappeared within a few days or months. We had made for us, fitted oversized new bushes to the conrods, and put everything back together.
I suggested, “We should start it before all the trouble of mounting it back into the chassis.” It ran for about ten seconds; there was a sound of breaking glass and much knocking. We removed a head and found the new sleeve had broken the land holding it at the top, and it had slipped into the bottom of the engine; oh, what a mess! Sometime in the engine's life, some dodgy work had been done, and the land groove was 0.006" too shallow for the new sleeve. Pays to check everything. Ted from down under.
Interesting on the pin bushings. I think you are right, they are loose so I can put things together in the field, and in frame, which makes me happy and the manufacture happy because I'm not complaining I had to beat the pin in and now it's stuck or the rod is bound up. It'll work for awhile.
I hope Jim’s son reads this. I couldn’t imagine the channel without you. I love the father son dynamic. I wish I had a relationship like that with my dad. We don’t. Never will. I love watching you two work together and the videos in general are made very very very well!
Appreciate that! Thanks for watching!
gotta love the comment section experts who think they know better then someone with 30-40 years experience vs their zero experience
Was thinking the same thing
They are the type of people who will not accomplish anything other than shining a seat with their butt.
Machinest are the last professionals held to a code of honor. I raise my glass to you gentlemen.
Probably 30 years ago I took not a diesel, But a gasoline engine apart and the first 2 bores were worn out way oversized compared to the second 2 and a machine shop explained to me. They figured out. It was poor coolant flow because the water pumps were really under sized for that engine. And that is the hottest part of the engine going back through the water pump to thermostat housing.
"Looks good to me....But what do I know?" I feel your pain. So many experts...who aren't.
It is beautiful that you are passing the knowledge on. Be blessed and may your measurements be accurate.
What I like about this channel is the knowledge you guys share and the father and dad aspect. I think that is great to see a son wanting to learn and follow his dad. Dad is a great teacher and has a huge amount of knowledge. Great channel
I am no machinist but understand what you are doing to these engines.
Pay no attention to the keyboard warriors. Keep the hairy cameraman handy and keep posting the great videos.
I own an independent diesel repair shop in Texas and we just don’t have any good and trustworthy machine shops near us anymore and therefore we refuse to do engine rebuilds in house anymore because the quality is just not there nowadays causing independent shops to refuse to do anything other than quoting customers full replacement because of the liability we carry and the machine shops never stand behind their work. I love seeing how thorough you guys are and wish you were more accessible to us because you are men of integrity, honesty and that’s sadly a rare attribute in the repair industry anymore.
I'm a bit surprised you haven't pulled the freeze plugs to check for scale build up on the cylinders. From the brief looks down the cooling passages, it does look like there's more than I'd allow to stay. Maybe boiling the block is in order.
Given how hot the rods got, do you run a cleaning wire through the lubrication hole, rod journal through to the the top of the rod, to clean out any baked oil?
You guys are very legitimate machine shop your customers are very lucky to have you guys working on your engines
Really enjoy the content. Here is a suggestion for additional content "Making bronze pin bushings on a CNC lathe"
Not only is it extremely satisfying seeing you rebuild these old motors but you guys do it with such a pleasant style and approach. And the fact it’s father son is the best part. Keep doing you. Screw the haters.
Write up a program in the fancy cnc lathe and knock out the bushings.
A great idea. Why having a CNC mill that is not used as intended?
Great job guys! Always doing great work. Have had brunt boots for 3-4 months now and are definitely the most comfortable boots I have ever worn. Even out of the box. Great product!
If you're running a Kubota in your Bobcat you need a Donaldson cyclonic clear bowl pre filter on the intake. I'd tip a cup full of fine dust out of mine after four hours work that would have otherwise made it into the paper air filters.
I love the knowledge, experience and craftsmanship on display here, much respect from Australia 👍🏻👍🏻
"You are the only one to complain" I hear that sentence -everywhere. They want to make You feel bad, question Yourself, maybe the error is on Your side.
This tactic is so widespread… Even my landlord: the heating is messed up, I´m freezing at night. I ask about it:"You´re the only one to complain".
Then they drag it out until You say "Fuck it" and go the expensive route. Customers can be glad Y´all do all the measuring and checking.

You guys are a great TEAM!
Really appreciated the insights into the potential unseen damage from overheating, very informative.
Enjoyed your video - great work - thank you.
Mate, grew up using inches and then flipped to metric in 1970's. Metric for most things is just plain easy. For "thou" you are metric anyway! As usual, absolutely LOVE these sessions!
The irony of the imperial system is that working in "thou" is metric divisions of a inch.
The real irony is that somebody would take time out of their day worrying about the units that measuring tools are graduated in to achieve the same exact result. The only downfall of the tools he is using is that he would need a calculator to figure out how many pistons stacked side by side would cover an acre LOL. Or how many would stack neatly inside a 5 gallon bucket.
Thou is thousands of an inch. You meant decimal. Just cause Metric is based on Base-10 math, doesn't mean you can call subdivisions of imperial "metric."
A thou is two and a half hundreds of a millimeter, or 1/40 mm. Sounds quite coarse when you think about it that way
@@erik_dk842 And tenth thou is ~ two & a half thousandths of a millimeter...
@@kstricl I have worked with a lot of guys older then myself in a shop that was metric because we worked on two basic parts for General Motors that were dimension in Metric. The reamed holes had +-.0125mm tolerance tho LOL. But John the one Inspector would come running in with his hair on fire "HEY THESE HOLES ARE FIVE THOUSANCE OVERSIZE"...we would have to remind him "John, those are Microns, and it is aluminum part that is 125F fresh out of the wash cycle"...and he would sheepishly say "Oh, yea...LOL".

Have lathe...make new bronze bushings to spec...done and dusted!
We had a load back in the early 00s on the 3 cylinder in arcgen welder generators. The radiator was too small and often got blocked. Was always cylinder no 2. We done 10 of them over 2 years in Scotland.
i had the reverse on cam bearings on a 55 allis chalmers. the aftermarket cam bearings were .005 too small and the manufacturer argued with me on the sizing. i found a new old stock at a local shop that used to sell parts and he had the correct bearings and the cam slid right in and is now running for 5 years. aftermarket seller would not give me my money back on product. don’t use them anymore
I try not to read the comments because they cause cancer, but I'm shocked that some said to get rid of your son on these videos.

Never seen anything heavy duty at Kubota.
Every factory service does that. Just put new. All because of warranty policies
I went through this on a V3007 (Cat C3.3B) in a Cat 906H loader. Overheated, combination of terrible radiator placement and operator. Scored the front cylinder the worst. 8k hours, the rest of the engine looked new yet. Bored .5mm over, got pistons from Cat. 1.5 years later they cooked it again, this time it took sleeves as no larger pistons are available. The Chinese overhaul kits off Ebay are actually pretty good quality. Cracked the head as well. I added a Murphy switch to hopefully protect it now.
I wonder if Depeche Mode sample the mallet vs valve tapping sequence 🤣
Hi from Sweden. Its not that long ago that inches where used by house builders and carpenters here. My late father, born 49, a timmerman (timber man, more like heavy carpenter) always used inches. It was 2 inch 4 etc for timber and 3 inch nails etc. Contradictory though he measured the timber in metric 😂. The folding rulers used to have both millimeters and inches on them but that's quite rare know. Most people still call them "tumstock" (inch ruler) though.
I do think it's easier to learn metric from the beginning but when you've learnt it you know it.
Keep up the good work.
oooooo what you just showed on them bearings alot of shops would of ran them that loose lots of respect too you guys

@racerich888 Well that's the only complication isn't it, how would he find that out by certainty. Some of them as you have seen have a chemical coating, why would he incur the risk of having the engine fail due to his bushing when they are cheap enough to get OEM ones and wait..
Crazy how bad the upper end was and the crank took so little to het back into shape! BTW I've wrenched on engines for a living for years and the wooly faced kid has taught me so much I didn't know having never been on this side of the rebuilding process. And he did it all through YT! 👏🏼
I work for VW and were running in to similar issues with cylinder heads. Exhaust valve guide seals are literally popping off of the guides. The max. Movement of the valve in the guide should be .8mm, I’m seeing heads measuring 1.2, 1.3 with only 40k miles on them. Then we get a brand new head, not even a reman and the clearance is at .8mm from the factory. Just unacceptable workmanship.
To answer your question if other technicians are receiving parts that simply don't fit like they are supposed to. Yes I receive parts that are not correct regularly. My workplace is a Linde lift truck dealership and linde does a fairly good job at quality control but when dealing with other brands of truck I have alot of fitment issues or changes to components that require completely different hardware in order to use.
What about machining ur own bushings in that new lathe ? Or machining an undersized set? I have no idea what material or treating process it would need or if it would be far too time consuming.
It's awesome to see a machine shop using a proflowometer on a stock engine your attention to detail Is awesome keep up the good work!
Of COURSE they're gonna tell you that you're the only one that has reported the problem with those pin bushings! You didn't think that they would be honest, do you?
My experience with Kubota is the reverse airflow. The cooling fan draws air from the engine area, blowing out through the rear of the radiator. Dirty jobs such as mowing plug the side screens and then it gets hot. It happens very quickly (minutes in hot weather) I noticed this and kept a brush handy and when the screens are plugged and heat begins to spike, I stop and brush it off. Proper cooling is the life of the engine.
Why don't you turn new bushings on your CNC lathe?
Check the weep hole in the water pump. I had been having coolant loss in an old IH TD15 that I couldn’t track down cause the water pump is buried way down inside the machine. The bearings finally left the building so after the pump was out you could clearly see it had been leaking for a long time. So yeah - check that pump.
Get some brass and and make new bushings!
you guys are great. lots of hard work and dedication here, not to mention technical knowledge. Don't pay any attention to the negative comments, fixing that boat anchor is not for the novice internet critic.
ya we had to eat a 20k motor from them we needed the loader back asap no parts around during covid. ours had cracked head. bad injectors can cause that also.
I have seen a lot of the short videos
This is my first full video
It’s great seeing a son follow in his father’s footsteps and a father teaching his son the trade
I have watched several car engine builders talking about how bad parts are getting
I know from experience that a lot of the smaller Kubota tractors have really weak fan blades, plastic that are easily prone to damage, too many people don't notice or don't care to fix it
The machine you did all the valve seats and guides im a little curious how the table moves so easy. The only thing i can think of how it works is air hockey. Am i close?
That's why it has those reddish air hoses attached...
@JohnSmith-pl2bk i figured was just curious. Not really knowledgeable about this stuff but its a family friendly show i can watch
