When you parked in the shop and you said, " This thing is sweet," I said, "It is." My wife said what it a wreck. I told her that the truck is awesome. I will definitely follow this build. Aloha Brother
I was one of the ones that built that truck worked the Exton plant until they shut it down. Now I'm retired and she's going back to work. Love the channel!
I Worry about you sometimes being alone in that shop and something bad happening. You need to start doing a little overkill on the safety side of things. I Know it's a lot of work to move all of that stuff away from the walls so you can put the crane together but at least you'll be safer lifting and moving things around the shop.
Matt, I agree with Scrappy. If you're going to do it, do it right the first time. If you want to bring this old girl back to life bigger and better than ever, go for it and go all in. She's well worth the effort from what I've seen in your videos. Make her the AutoCar 2.0!! 😁
Exactly what I said, it would be difficult to get those numbers on a 400 but if it was how longs that chassis going to last, rearends, clutch.. I mean 260 hp to 600+ is a big difference..and for what a truck he uses 1000 miles a yr..stupid..rebuild a stock 400 and it might last longer..
I would have the crank checked. It might be bent for just that one main to be bad. Your correct about 650 from a 400. Still he should have the crank checked out.
What, you mean throwing big injectors and tweaking the computer set points so far out of spec you need binoculars to see the new performance curve is bad for the engine? Say it ain't so! I'm surprised the other bearing didn't look like hammered turd with as bad as that main was.
Great content thanks! Just my .02, I think you would be happier doing a rear gear change to get the road speed up. You would have to do the math to get the correct Ratio
Those Big Cam Cummins are good engines. My father had a 1989 Kenworth K100 Aerodyne Cab-over with one in it. When it sold it to a junkyard in Toledo, Ohio in 1998, it had 2.2 Million miles on it. Engine wasn't rebuilt ever. Just really tired.
That metal is all through all the oil galleries and every passage in the crank, etc, that needs tore down and flushed in a hot tank or some such. Good call.
What's wrong with 220/230 hp? Ran all over the central states back in the 70's. Lol. Not fast but we worked by the hour in those days. Retired now 76 years old. Last truck I drove was a Freightliner with a 500 Detroit. 78 mph uphill & down. 1006000. Only replaced 2 o rings. Great truck!
I Went to Citrus College , They Had a 2 year Truck & Diesel Tech school, We Took a Old Autocar and Totally overhauled it from the Ground Up, eng. trans, diff, Suspension wiring, Every thing was Renewed, That was a Awesome Learning Experience , It had a 220 Cummins with the Compression Release 🤪 I Think it had a 5 and 3 Trans, the Diff. was a Worm Gear Configuration I just graduated High School and Jumped into Truck and Diesel Repair, Yes I am a Tomboy, I am Retired now, with over 50 years of Experience, It Payed The Bills 😛, Nice Project, Take care, Chellie
It blows me away how you Joe Everybody's who are just living your lives can film yourselves and be so natural and entertaining. I came across your channel completely by mistake one day and I just love watching everything you do. You are living the diesel dream. Keep on being awesome Matt.
Yup... There used to be only three networks and a couple other channels to watch on TV; I gave up on watching broadcast television for a couple decades, but, now, there is a lot more, much higher quality, and more specific content available for any interest... I have to make sure I'm not losing productivity with all of the good channels these days, but I don't mind spending time on Diesel Creek. Cheers! (Edit- I also stumbled on this channel, while researching draglines a few years ago. I've rarely missed a vid since.)
Yeah, there are some RUclipsrs that are great for making you feel like you are right there in the shop talking to them the whole time they are working. Like you are standing there drinking a beer while you watch them working. Mustie1, Watch Wes Work, James Condon all come to mind. Those are the best channels. Entertaining, educational, and immersive.
Yeah I came cross him a few years ago by watching excavating channels (letsdig and DP). Little did I know how much I have in common with Matt. Farm craft is another I can relate too. Just into a little bit If everything and not afraid to push there skill and knowledge. I love it.
@centauri61032 Haha! Yes. You named 3 of my top tubers. Then there's MartyT and a couple others. Check out Inheritance Machining and you might like Northwest Hillbilly, or something like that.
We always put C-clamps with handles - up on the ends of the forks when using slings to lift anything. The C-clamps keep the slings from sliding off the end of the forks, keeping the lifting chore much safer. Sorry that engine needs a complete rebuild, but that's the safest way to assure that it's a good engine and going to last without problems for you. I do enjoy watching your ventures, both good and bad, but hopefully not too bad. You really amaze me when you get something running that hasn't run in 30 + years. Showing reality in the videos makes them more believable to watch and more interesting. Please keep making videos the way you have been. I watch because they show the reality, both good and bad.
I was thinking the same thing on the sling and clamps. As the engine went to the left, the slings started to move with it. If there had been clamps on the forks, the sling could not slide.
You may consider a headache rack, with storage for your chains, protect YOU from broken cables and chains. It would make a place to make a hanger for your airlines a little neater, and hydraulic lines from your wet kit . (nothing worse than tangled greasy airlines, use a cable swivel to to hang the springs from so things swing nice and not get caught on stuff,
I don't comment much, ex a Vietnam vet living in the UK, but you sure have come a long way fast, and made your dream a reality, well done what a fantastic new building you have now. Well Done, Enjoy , ohhh Nice to see the Flag hanging proudly,, whoooo Rahhhh
Inspect that main cap with the thin bearing really well and make sure the bearing didn’t spin in the cap. If it did you need to have the block line bored. The material you are seeing on the other main bearing probably came from that thin bearing.
@@bholdr----0 the bearing is stationary in the cap, sometimes if an engine starves for oil the bearing will stick to the crank and spin in the block, if that happens it takes material off the block where the bearing sits and can cause alignment issues. The block needs to be line bored to correct that. Not saying that happened in this case, just needs to be thoroughly inspected.
Great video as usual Matt! Another good reason for a full rebuild - flushing all the oilways to remove any traces of metal that could still be in them; it's not worth risking crud getting into a new set of bearings or doing other damage.
It’s just past 11 PM here in Tokyo and am preparing to watch Matt work his magic on the AutoCar. It’s always a pleasure to see him restore “old iron “ to working condition and giving it a whole lotta love. Well done Matt!
Bummer about the engine, but you have got this. Tiny contribution from my side of the world. Keep up the great work Matt, you have one of the most enjoyable channels to watch.
Matt, you need to rethink the way you lift stuff like that engine. You were lifting it from well below its centre of gravity, and it was no surprise to me that it went pear shaped. Others have suggested having clamps on the forks to prevent the rigging gear slipping off, - not a bad idea although I would prefer it to be tied back to the fork frame with another sling which would avoid any chance of a clamp slipping off in any sudden impact or jolt. You also could have used the lifting lugs between the cylinder heads as a guide for slings anchored to the rear engine mounts that you were lifting from with the fork, and using a chain block as an adjustable link to gently move the unit to the vertical position.
@@dangoodwin5954 No, that was an accident. People will watch ingenious things done right. He needs an engine lift or make a couple stands that help manipulate engines. This is a good way to kill yourself, and he films alone so nobody would know it happened.
Sad to see the Old girls 855 Cummins leaving such a reliable engine From what i can See on all the videos I bet the 855 would do better if axles abd transmission was re geared Matt 9:18 @Diesel Creek
Great to see the orange AutoCar ConsTRUCKtor getting a new powerplant 👍 Shame it hasn’t worked out quite how you wanted but it completely makes sense to do the teardown and rebuild before you pop it back in the truck. Thanks for taking the time to bring us along for the ride.
Heck yeah. I dig this truck- the long nose, the gnarly tires, the winch, the color: It just screams personality... and if that motor really ends up pushing 650- jeez, I don't even know.
that small cam engine would make for a great power plant. they're actually really decent on fuel and always reliable. You should look at repurposing it for that.
Yo Matt, this cold turkey is gettin too much... where are you man... Even a quick video of you sweepin out the work shop will do, anythin to take the edge off.. Respect..
It's not like you don't have enough going on already 😂 New project idea... That engine stand you don't have. Build one. Sam has the example and probably some ideas to improve on it.
I agree. One mishap could end your career and our joy of riding along. You’re doing what a lot of us would like to be doing. BE SAFE and go to church on Sundays. He’s giving you lots of passes. ❤❤❤❤
Being that you're in Western Pennsylvania, you could paint it the same shades as the Bessemer & Lake Erie Railroad (orange and black). That could be an homage to the area mining, steel and railroads. Also if you want to get rid of mice, mix Jiffy cornmeal mix 50/50 with baking soda. Rodents can't get rid of gas like other animals so they essentially blow up. It won't hurt dogs, cats or birds.
As a diesel tech for many years you need to be more concerned with deposits on the crank more so than small groves. Deposits will grip the bearing groves hold oil. When checking rod bearings always check the rod side for wear mains can wear either side some engines are worse than others about which bearings wear worst. Be careful buying after market parts I have seen many of these kit’s come in with cylinder damage and have never seen 1 warrantied. They claim installation error normally without seeing the damage. Your oil should never be silver small speck of metal yes but very small the amount of silver in that pan was a clear sign of a failure of some type. Based on the color it was aluminum with there very few aluminum parts in an engine. The piston skirts being largest if not the only source. I believe I’ll call BS on the 650HP. Will say that the galling of the cylinder is a possible side effect of turning up the fuel
Smart move would have been to get the engine stand from Sam! ASE Certified Truck Technician that worked on hundreds of Cummins 855s in frame out of frame.
Every time a video of this truck gets posted, I drop what Im doing to watch it. I feel like a kid watching a brand new episode of my favorite cartoon. I can't put my finger on it but something about this truck just excites the heck out of me.
Yeah, me too. When I was a kid, Autocars were all over the place as garbage trucks and dump trucks and they seemed as big and imposing as a house. Now as an adult they STILL seem as big and as imposing as a house😵💫
Matt, for the cost of the overhaul at this point will be the best way to know that you have a clear core to make sure that it is free of any debris in the oil galleries. I agree that knocking the "650* hp back to "400/450" makes SENSE as you want better life on the rebuild.
Years ago I drove a GMC 5 Star General that had a 400 big cam with a 13 speed Eaton. It was hooked to a 38 foot detachable trailer. It's primary use was to transport a Komatsu PC 200. It had more then enough power to pull the load no matter how steep the hill was. I loved that truck as you could spin it around a donut with that set back axle.
Bummer on the engine but WOW what a slice of history that your Autocar lived in the shadow of the Silver Spade. It is a crime the Spade and Gem both were scrapped along with the Captain and Big Muskie. All incredible pieces of engineering the likes of which we will never see again. Thank you for preserving slices of history.
Sorry, but NONE of those machines were truly available for private party purchase. Big Muskie and the Gem were "retired" by the mine owners and scrapped on site. The Captain suffered a fire that was determined to be too expensive to be repaired and thus scrapped by the owners. There was a significant effort and a crap ton of money raised to preserve the Silver Spade but Consol Coal worked every last minute of life out of it and deferred maintenance. Thus when they were we walking the shovel out of the pit on it's way to a paid for preservation site the swing circle bearings fell the "F" out and it was scrapped in situ by the owners. Perhaps those old 1965 POS crawler transporters used to transport the Saturn V to pads 39A&B which took man to the moon should have been scrapped after Apollo? Ooops, wait they carried ALL the space shuttles and now are integral to the Artemis return to the moon missions. Bet the Pyramids would make great crusher run. @@jdcatskinner
@@spencerjhog4429 wow lay off the meth nobody said anything about the pyramids. And yah they should scrap them space transporters. They have no usable value other than scrap.
Working alone without getting injured, or breaking things that you need, takes planning and patience. A little time can save Lots of money, heartache and pain.
If you take the time to do things right, you'll be able to haul everything you own wherever you want. So you could do what you're going to do now is why you built the shop in the first place. Great content, looking forward to the rebuild.
My absolute favorite parts of all your vids are the 'real life' portions. We all have them brother and it is refreshing to see that even guys like you struggle. Love this channel!
Orange and black would look cool. But i think at least that radiator surround should stay matte aluminum. Also, one thing to keep in mind when checking engine bearings is where the forces are being applied. On the connecting rods, all the load will be on the upper bearing shell from the combustion pushing the pistons down. The main caps will have the wear on the bottom bearing shells. The reason that one lower main bearing didnt stay in the cap is due to one thing: heat. That bearing was the first one to get starved for oil and got hot. Had that engine run much longer, it would have spun that bearing around and damaged the block. I'd say you caught it at just the right time.
I'm not a boy, but I have watched your videos for quite a while. I enjoy every bit of what you work on. I can hardly wait to see what is next for that engine. Thanks for sharing! 😊
Yer not a boy? Who cares? (At least, no one should, eh? Good for you, and anyone into this supercool stuff.) For my part, the enthusiasm that Matt has for his projects makes me feel like a boy again, sometimes, reminds me of working on diesel gear decades ago, with my grandpa... and my sister.
@Car-dash-Ian That would be awesome, but I am a Grandma, and I live in Arizona. Too far away. Most definitely been to Pennsylvania, That was a very long time ago. Grew up wrenching with my step-father, and he told me, if you have a vehicle, learn to work on it!
Good engine choice. The big cams are a popular choice to put into old deuce and a half trucks to wake them up. It will be worth the headaches once you're done.
Just love the ETHER can holder permanently attached to the front bumper 😀😀👍👍 I'll take one with a magnet attachment for my tool box with a Diesel Creek sticker
What's next, you're gonna put a sleeper on it? So much work! Excited to see how it comes out. Glad you're keeping it orange, personal favorite of mine. Also funny he says that he wish he had an overhead crane, and it was the autocar that hauled one onto his property.
Thank you Matt. Bummer on the engine. But, when you get done, you will know what you have. And that is what you wanted, reliability. You will be able to take it 200 miles or 2000 miles without any problems. Will be interesting to watch the progress and the upgrading of your truck. Cheers.
Oh good!! A project - I like project videos (even when it's a many-part series) MUCH better than the "Can we make it run?" videos. So THIS is going to be fun to watch. Thanks for sharing it with us. I love that you go through your list of objectives first and then tackle things. And I love the narration over time lapse stuff you do. Keep up the great work, Matt!!
My nabor switched his engine in his 8000 Ford dump truck a number of years ago. He took the 275 hp Cummins and switched for a 425hp Cummins. Now he's having trouble breaking input shafts, and the frame had to be reinforced to prevent twisting from the torque. At least you'll know what you have in that new motor, though, so thats a plus.
He upped the horsepower by 150. That's over 50% of what he had before. It's no wonder his poor 8000 is being bullied by that thing, it wasn't _designed_ with that much power intended for its frame!
Love your channel man. I am now retired after having spent 45 years as a heavy duty diesel truck mechanic. From what I see from your video is a piece together big cam II block. I firmly believe that Joel Hack amoo was the mechanic that assembled this engine. To get 650 horse out of this 855 block you need to feed the fuel passage in the heads from both ends of the engine. The scored cylinder I believe is from a rolled O-ring from the lower liner packing seals of that cylinder. I believe area diesel services will do you right and helping you find a good CPL to build this motor to. There’s no reason you cannot build that block to a very nice 500 hp and it will live. There’s no such thing as bad engines it’s just bad mechanics.
i didn't realize how affordable the rebuild kits are, you could blow the 1500 relatively quick if you had to tow the truck, seems to me like cheap insurance/good content so the rebuild seems like the win
The thing has a standard intercooler, 650hp tuning will probably put the exhaust temperature through the roof, fry the valves and cook rings if the thing is held at peak torque for any length of time. I think you should put the thing back to stock, but if you don't at least put a temperature gauge on the exhaust manifold and change down when it's getting hot. I wonder if the radiator will take all extra heat? The book figure for the 400hp is 9250 btu/min- 163kw to the radiator, probably twice the old small cam engine.
You'll need to check the size of the air filter and exhaust muffler/silencer as well, air and exhaust flow are going up from small cam to 400hp big cam, and Cummins have limits on inlet suction at the turbo, and exhaust back pressure.
@@oldmuppet191I can personally attest that you want a set of mufflers on a BigCam 400. A buddy of mine had an Awefulcar (as he called it) Constructor with a Holmes 750 wrecker on the back that had straight pipes and going down the road without a load on it was painful to the ears but with a load and decelerating with the Jake’s on made sitting in the front row of a Who concert sound like a whisper
The issue with buying rollover engines is in many cases once a driver evacuates the vehicle they normally do not go back to shut them off! I have been early to a few truck crashes where you could hear the motors pooch themselves out. A few years back I witnessed a Cat bulldozer run rolled over for about 15 minutes before it went bang!
A farm tractor versus train crash I helped a towing company clean up, the engine was torn from other parts of the tractor, the engine was laying on its side running off crankcase oil getting in the turbo when the fire department got there. They turned it off with two dry chemical fire extinguishers in the turbo. Ugly crash.
I'm sure you've heard of them but I think you could use a aqua blaster. Mr Hewes has just done a great video on how useful they are when working on large vehicles. The power of sandblasting with the convenience of a jet washer.
I'm very glad you referenced the Mr. Hewes Aqua Blaster video, I hope Matt checks it out. The system shown on the video is probably one of the highest tech / highest cost option for Aqua Blasting. It's good to know that there are much cheaper option that simply attaches a syphon type nozzle to your existing power washer, they seems to work just a well as the high tech systems. Example; ruclips.net/video/kfA-IkaMRGE/видео.html I think Matt could easily find a Wet Sandblasting company that would be happy to sponsor him testing their setup.
I like this old truck, and i would upgrade it to be a usable hauler to, because having it just parked to look at with a motor that can't work for you just makes it a lawn ornament. I'm looking forward to an older truck you've got parked to be restored. I know you have a better cab for the old girl, and having money and parts will help. That power company robbing you to get the power hooked up was a wallet buster, and then all the money to run power to the building added up quickly, plus the building and concrete wasn't cheap, so i get having to prioritize where the fund's go. G-d bless.
Matt, you can do what you want, but if it was me, I would pull that crank, mich it and if the dimensions are good all the way down the line I would get it polished and go back together with it. Clean that blocks oil galleries good because they are how the metal got into those bearings. I would hate to spend that much money and time installing it and have some aggravating noise haunt me every time I go to start it and plan on a 600 mile trip. I like the ides of that old gal getting out on the road and can run with most of the trucks on it. You turn a lot of fuel in on the original engine and you're right, there will be spider webs all over those pistons. Like your videos.
I rebuilt my big cam , and was amazed at the cost here in Uk , the cost compared to European engine rebuilds was way cheaper. Less that 50% ! The kit including oil , filters , exchange heads, injectors , the pump was rebuilt and upgraded , plus everything needed . I don’t know how much more it would cost now but I found the service I had from Cummins UK was second to none . I would recommend doing a full rebuild , it will pay in the long run .
Don't pull the cam unless you have access to the special tools to reset the cam follower boxes. Those boxes set the injection and valve timing and MUST be right. The gaskets for the follower boxes are actually shims and I would not feel comfortable just reusing the old shims. Who knows if the guy before you did it right?? I would guess the engine got hot, which is what ruins pistons and liners quickly. It looks like your engine is a Big Cam 3, which is good. The Big Cam 4 engine has a low-flow cooling system requiring a specific radiator. I found the Big Cam 4s to be very prone to overheating. Beg or borrow the engine stand. It bolts to the side of the block and will make this job MUCH easier.
YES. Follower alignment and spacing is CRITICAL in these applications. It's not hard if you have the tooling, the procedure, and a touch of patience, but it is very important. And yeah, a proper stand or, even better, rotator, would be near essential for an out-of-frame on one of these old gals.
I seen that the engine was going to fall, I yelled, I guess you didn't hear me. Also when working on something you want to save, be more careful of lifting apparatuses you use. When they slip result usually aren't pretty and are expensive. Pushing \lifting with Forks isn't real stable and when they slip they do alot of damage as you found out. Love your videos!
BAD advice. There most assuredly is metal scattered everywhere. ESPECIALLY in the cam bearings. PULL THE CAM. Will be stupid not to. With Matt's contacts, someone has the tools and skills to get things set. J.C.Smith just covered this on his channel. (Setting things, not my cam bearing statement).
When I first learned to drive I started using the approach to manual gear change we call "double de-clutching" which is to spin up the gearbox between changes so that you match the gears to engine revs giving any synchros an easy life. It became second nature and is the way I always drive. You may already do this bu if not - try it. In the early days, I practised when driving my employers vans, changing gear without use of the clutch at all once the van was moving. Great fun.
Sad to see she needs some loving but good to see you intend to give it to her. As others have mentioned, I'd consider knocking her down a bit to extend her life. Somewhere in the 500-525hp range should give you all the power you need, especially with the rear-end gearing it has without putting excessive stress on the ol girl. Can't wait to see her get fixed up and tearing that Autocar down the highway. 😁👍
@DieselCreek my ol man has an '86 Freightshaker tandem axle dump with a big cam in it and stock it has the power to take enough weight off the front end that it won't steer when loaded down and your foot on the floor 😂 it's only got an 8 speed Eaton in it too.
Bummer it's hurt alittle but it will be 100% when you are done. This truck has a special place in my heart you bought it from my very good Friend Brayden from Dying Bread Diesels. Can't wait to see her up and running.
Im with masongillespie, im not a cummins expert but 650hp is much more power than i have heard if a big cam having much life. Glad tto here your making a teardown. I thing you will be happier where you plan on keeping the truck for a while. You might think about turning it back to 500hp or a little less. Good luck
One thing in cautious about a crash engine happened to my uncle. He had a driver roll a International with a V555 cummins he fitted new cab and straightened chassis but after that the 555 would loose oil pressure when run long enough to get oil hot and determined that it had an internal crash in block from crash. Was fine working local on stop start but go distance and oil pressure go buy buy
westport wa.state here. i am not an armchair QB type. not any education in big old trucks. for that reason i'm in. love to learn. so i will shut up and watch.
You can change those crank bearings in the engine. Obviously, they didn't rebuild it fully. Maybe new pistons and rod bearings. Maybe a valve job but all done in the truck. The Babbit worn off the mains is old age, not from running upside down. Same with cly walls. That engine was not rebuilt, only patched up.
650 Hp with a Big 400 Cam That is why them bearings look that way and also why the Piston Skirt Liner is gouged so bad on cylinder 1 looks like it was Starving for oil a bit if you Took 150 or so Horse Power out the motor And It was More like 400Hp the engine would Last Longer Have less problems.. That is A ton of power And Wear and tear on that 855 Cummings Block Matt 29:45 to 31:15 @Diesel Creek
Mat, back in the '80s, I drove / operated a 330" wheel base Autocar gin pole truck for Lufkin pump jack repairs. It was a MONSTER. I miss those days, and we bought 242 Lufkin 360 pump jacks from a Phillips field in northern Oklahoma and disassembled and hauled 150 miles back to Oklahoma City at three a week. I drove a Mac R model to go and pick them up as well. I would piggy back two flat bed trailers to get to the location. We three people to do this task, I would start by hot wrenching all the nuts and bolts, then load on the trailers with the AJAX engine as well.
I like the direction that you are going with this engine. In my view you too often want to 'luck out', whereas the most satisfying experience is when you do a righteous job, as you have set out to do on this machine. Plus there will be some personal growth and likely more viewers in this engine rebuild.
Sorry for the discovery on the engine Matt. Go borrow that engine stand, it will be worth the effort. I almost fell out of my chair when the engine slipped on the forks. Lol Ok, looks like there was a wood boiler sitting in the back of the truck parked next to where the Autocar was parked! Could it be? Looking forward to the rebuild. Thanks
Watching your vids have helped me keep my own project going. I am working on a 94 k2500 with a 6.5 turbo diesel and since I live in a cold place things have taken time. I have been close to giving up but thanks for inspiring me to keep going. I just need to be more patient and not stress, as it will take time to get it looking its best.
My project is a 95 k1500 with the 5.7, and I need to get back to it. I have a little more to do to get it on the road, I just need to do it. Good luck with your k2500. You'll be blowing black smoke in no time!😁
I would highly recommend replacing the crankshaft seals on the big cam engine while you’re in it. I didn’t on a S60 with similar history and have regretted it. Dripping leaks on a basically new motor gives everyone the wrong impression. Super fan of your work, keep it up 🤠.
If you could determine if the seals were replace during the prior rebuild, you might be able to let it slide, but the chunky debris you’ve already found could also be trapped behind the sealing lips could cut the seals lifespan. I vote for keeping some orange in the paint scheme.
This trucks ties to the Silver Spade is big. I’m real sure You understand the historical significance better than most people. I can understand why You want more speed and power. It would make a wonderful low boy tractor. If that big cam was mine, I would suggest line boring the main caps .
I would do some careful measurements on that crank. Maybe someone did some home brew polishing on it and it is not sized correctly. Good luck Matt. Just do it all right and have a good engine that will last for a long time. Shoot…could even move it to another truck later if need be…so don’t worry about “wasting money” on it.
We had a big cam 350 that was turned up a bit in a spud truck. Also very low geared, but the Eaton Fuller 13 spd made it okay on the highway. Oddly enough, our Ford had the same winch. It was an oil field truck. With a 22’ self unloader, it was a great truck. It had the same Hendrickson walking beam suspension too. With those deep lugs and the walking beam, that thing will go almost anywhere!!!
Matt, I really enjoy your channel and all the growth in shop and equioment. Your mechanical know how amazes me. My Dad was a real mechanic, self taught and a deisel fleet mech. He was like you, he could make anything run.

Love seeing comments like these. Loop completed!
I Worry about you sometimes being alone in that shop and something bad happening. You need to start doing a little overkill on the safety side of things. I Know it's a lot of work to move all of that stuff away from the walls so you can put the crane together but at least you'll be safer lifting and moving things around the shop.
"Shake Hands With Danger" was playing in my head the whole time you flipped the engine 🤣🤣🤣 For sure I will love this build!
Same here 😂 would've been so funny had he inserted the guitar riff there that we all know so well
Matt, I agree with Scrappy. If you're going to do it, do it right the first time. If you want to bring this old girl back to life bigger and better than ever, go for it and go all in. She's well worth the effort from what I've seen in your videos. Make her the AutoCar 2.0!! 😁
650 hp out of a big cam 400 is why those bearings look the way they do. Knock 150 hp right off the top and she’d live a lot longer.
Exactly what I said, it would be difficult to get those numbers on a 400 but if it was how longs that chassis going to last, rearends, clutch.. I mean 260 hp to 600+ is a big difference..and for what a truck he uses 1000 miles a yr..stupid..rebuild a stock 400 and it might last longer..
I would have the crank checked. It might be bent for just that one main to be bad. Your correct about 650 from a 400. Still he should have the crank checked out.
What, you mean throwing big injectors and tweaking the computer set points so far out of spec you need binoculars to see the new performance curve is bad for the engine? Say it ain't so!
I'm surprised the other bearing didn't look like hammered turd with as bad as that main was.
Great content thanks! Just my .02, I think you would be happier doing a rear gear change to get the road speed up. You would have to do the math to get the correct Ratio

Those Big Cam Cummins are good engines. My father had a 1989 Kenworth K100 Aerodyne Cab-over with one in it. When it sold it to a junkyard in Toledo, Ohio in 1998, it had 2.2 Million miles on it. Engine wasn't rebuilt ever. Just really tired.
Toledo ohio here ☝️ lol
That metal is all through all the oil galleries and every passage in the crank, etc, that needs tore down and flushed in a hot tank or some such. Good call.
This would be my biggest concern too... Metal bits throughout......
Get yourself a couple of pieces of plywood to lay on the floor to set heavy parts on will help prevent damage to that nice concrete floor
What's wrong with 220/230 hp? Ran all over the central states back in the 70's. Lol. Not fast but we worked by the hour in those days. Retired now 76 years old. Last truck I drove was a Freightliner with a 500 Detroit. 78 mph uphill & down. 1006000. Only replaced 2 o rings. Great truck!
I Went to Citrus College , They Had a 2 year Truck & Diesel Tech school, We Took a Old Autocar and Totally overhauled it from the Ground Up, eng. trans, diff, Suspension wiring, Every thing was Renewed, That was a Awesome Learning Experience , It had a 220 Cummins with the Compression Release 🤪 I Think it had a 5 and 3 Trans, the Diff. was a Worm Gear Configuration I just graduated High School and Jumped into Truck and Diesel Repair, Yes I am a Tomboy, I am Retired now, with over 50 years of Experience, It Payed The Bills 😛, Nice Project, Take care, Chellie

Yup... There used to be only three networks and a couple other channels to watch on TV; I gave up on watching broadcast television for a couple decades, but, now, there is a lot more, much higher quality, and more specific content available for any interest...
I have to make sure I'm not losing productivity with all of the good channels these days, but I don't mind spending time on Diesel Creek.

Yeah, there are some RUclipsrs that are great for making you feel like you are right there in the shop talking to them the whole time they are working. Like you are standing there drinking a beer while you watch them working. Mustie1, Watch Wes Work, James Condon all come to mind. Those are the best channels. Entertaining, educational, and immersive.

We always put C-clamps with handles - up on the ends of the forks when using slings to lift anything. The C-clamps keep the slings from sliding off the end of the forks, keeping the lifting chore much safer. Sorry that engine needs a complete rebuild, but that's the safest way to assure that it's a good engine and going to last without problems for you. I do enjoy watching your ventures, both good and bad, but hopefully not too bad. You really amaze me when you get something running that hasn't run in 30 + years. Showing reality in the videos makes them more believable to watch and more interesting. Please keep making videos the way you have been. I watch because they show the reality, both good and bad.
I was thinking the same thing on the sling and clamps. As the engine went to the left, the slings started to move with it. If there had been clamps on the forks, the sling could not slide.
Yah… a guy gets in a hurry sometimes lol

Matt have a little fun put the big cam fuel pump on the small cam doesn't take that long to do see what happens you will like it
Inspect that main cap with the thin bearing really well and make sure the bearing didn’t spin in the cap. If it did you need to have the block line bored. The material you are seeing on the other main bearing probably came from that thin bearing.
I don't completely understand, why does that spinning mean that? (What am I missing?)
@@bholdr----0 the bearing is stationary in the cap, sometimes if an engine starves for oil the bearing will stick to the crank and spin in the block, if that happens it takes material off the block where the bearing sits and can cause alignment issues. The block needs to be line bored to correct that. Not saying that happened in this case, just needs to be thoroughly inspected.
@@mjmcomputers oh ok
Duh. Thanks!
Great video as usual Matt!
Another good reason for a full rebuild - flushing all the oilways to remove any traces of metal that could still be in them; it's not worth risking crud getting into a new set of bearings or doing other damage.
It’s just past 11 PM here in Tokyo and am preparing to watch Matt work his magic on the AutoCar. It’s always a pleasure to see him restore “old iron “ to working condition and giving it a whole lotta love. Well done Matt!

I’m having withdrawals too! It’s been too long!
Where you at buddy? Real miss ur videos! Hope all is well!
Matt, you need to rethink the way you lift stuff like that engine. You were lifting it from well below its centre of gravity, and it was no surprise to me that it went pear shaped. Others have suggested having clamps on the forks to prevent the rigging gear slipping off, - not a bad idea although I would prefer it to be tied back to the fork frame with another sling which would avoid any chance of a clamp slipping off in any sudden impact or jolt. You also could have used the lifting lugs between the cylinder heads as a guide for slings anchored to the rear engine mounts that you were lifting from with the fork, and using a chain block as an adjustable link to gently move the unit to the vertical position.
Um.....people don't watch if nothing goes wrong, it's not an accident. 🤷♂️
@@dangoodwin5954 No, that was an accident.

Great to see the orange AutoCar ConsTRUCKtor getting a new powerplant 👍 Shame it hasn’t worked out quite how you wanted but it completely makes sense to do the teardown and rebuild before you pop it back in the truck.
Thanks for taking the time to bring us along for the ride.
😢😢😢😢
Heck yeah. I dig this truck- the long nose, the gnarly tires, the winch, the color: It just screams personality... and if that motor really ends up pushing 650- jeez, I don't even know.
Looking forward to this series of the auto car. It isn’t the original auto car but this one will work
@@mickdu2515 I’m not forgetting the OG Autocar, this one just takes priority because it will actually work. The 57’ it just gonna look pretty
that small cam engine would make for a great power plant. they're actually really decent on fuel and always reliable. You should look at repurposing it for that.

Being that you're in Western Pennsylvania, you could paint it the same shades as the Bessemer & Lake Erie Railroad (orange and black). That could be an homage to the area mining, steel and railroads.

How can we love Earth if we harm her creatures.
As a diesel tech for many years you need to be more concerned with deposits on the crank more so than small groves. Deposits will grip the bearing groves hold oil. When checking rod bearings always check the rod side for wear mains can wear either side some engines are worse than others about which bearings wear worst. Be careful buying after market parts I have seen many of these kit’s come in with cylinder damage and have never seen 1 warrantied. They claim installation error normally without seeing the damage. Your oil should never be silver small speck of metal yes but very small the amount of silver in that pan was a clear sign of a failure of some type. Based on the color it was aluminum with there very few aluminum parts in an engine. The piston skirts being largest if not the only source. I believe I’ll call BS on the 650HP. Will say that the galling of the cylinder is a possible side effect of turning up the fuel
Smart move would have been to get the engine stand from Sam! ASE Certified Truck Technician that worked on hundreds of Cummins 855s in frame out of frame.
Every time a video of this truck gets posted, I drop what Im doing to watch it. I feel like a kid watching a brand new episode of my favorite cartoon. I can't put my finger on it but something about this truck just excites the heck out of me.
I know EXACTLY what you mean.
Yeah... makes one feel like a kid on saturday morning!
Yeah, me too. When I was a kid, Autocars were all over the place as garbage trucks and dump trucks and they seemed as big and imposing as a house. Now as an adult they STILL seem as big and as imposing as a house😵💫
@@cmans79tr7 i had a model kit of the same truck as a kid now 60 i want another
Matt, for the cost of the overhaul at this point will be the best way to know that you have a clear core to make sure that it is free of any debris in the oil galleries.
I agree that knocking the "650* hp back to "400/450" makes SENSE as you want better life on the rebuild.
Years ago I drove a GMC 5 Star General that had a 400 big cam with a 13 speed Eaton. It was hooked to a 38 foot detachable trailer. It's primary use was to transport a Komatsu PC 200. It had more then enough power to pull the load no matter how steep the hill was. I loved that truck as you could spin it around a donut with that set back axle.
Bummer on the engine but WOW what a slice of history that your Autocar lived in the shadow of the Silver Spade. It is a crime the Spade and Gem both were scrapped along with the Captain and Big Muskie. All incredible pieces of engineering the likes of which we will never see again. Thank you for preserving slices of history.
How is it a crime anyone could have bought them before they were scraped but nobody wanted to spend the money to buy them and move them
@@jdcatskinnerIt's a crime that something like those chunks of history were just left to be scrapped.
@@airplanemaniacgaming7877 haha there's no reason to keep worn out equipment or obsolete equipment.
Sorry, but NONE of those machines were truly available for private party purchase. Big Muskie and the Gem were "retired" by the mine owners and scrapped on site. The Captain suffered a fire that was determined to be too expensive to be repaired and thus scrapped by the owners. There was a significant effort and a crap ton of money raised to preserve the Silver Spade but Consol Coal worked every last minute of life out of it and deferred maintenance. Thus when they were we walking the shovel out of the pit on it's way to a paid for preservation site the swing circle bearings fell the "F" out and it was scrapped in situ by the owners. Perhaps those old 1965 POS crawler transporters used to transport the Saturn V to pads 39A&B which took man to the moon should have been scrapped after Apollo? Ooops, wait they carried ALL the space shuttles and now are integral to the Artemis return to the moon missions. Bet the Pyramids would make great crusher run. @@jdcatskinner
@@spencerjhog4429 wow lay off the meth nobody said anything about the pyramids. And yah they should scrap them space transporters. They have no usable value other than scrap.

Hope everything is alright Matt and you’re just in a much deserved vacation!!
Orange and black would look cool. But i think at least that radiator surround should stay matte aluminum.
Also, one thing to keep in mind when checking engine bearings is where the forces are being applied. On the connecting rods, all the load will be on the upper bearing shell from the combustion pushing the pistons down. The main caps will have the wear on the bottom bearing shells. The reason that one lower main bearing didnt stay in the cap is due to one thing: heat. That bearing was the first one to get starved for oil and got hot. Had that engine run much longer, it would have spun that bearing around and damaged the block. I'd say you caught it at just the right time.
I'm not a boy, but I have watched your videos for quite a while. I enjoy every bit of what you work on. I can hardly wait to see what is next for that engine. Thanks for sharing! 😊
Not all girls enjoy needle point. Enjoy the ride like the rest of the boys.
Yer not a boy? Who cares? (At least, no one should, eh? Good for you, and anyone into this supercool stuff.)
For my part, the enthusiasm that Matt has for his projects makes me feel like a boy again, sometimes, reminds me of working on diesel gear decades ago, with my grandpa... and my sister.

I love that you go through your list of objectives first and then tackle things. And I love the narration over time lapse stuff you do. Keep up the great work, Matt!!
My nabor switched his engine in his 8000 Ford dump truck a number of years ago. He took the 275 hp Cummins and switched for a 425hp Cummins. Now he's having trouble breaking input shafts, and the frame had to be reinforced to prevent twisting from the torque.
At least you'll know what you have in that new motor, though, so thats a plus.
He upped the horsepower by 150. That's over 50% of what he had before. It's no wonder his poor 8000 is being bullied by that thing, it wasn't _designed_ with that much power intended for its frame!
Love your channel man. I am now retired after having spent 45 years as a heavy duty diesel truck mechanic. From what I see from your video is a piece together big cam II block. I firmly believe that Joel Hack amoo was the mechanic that assembled this engine. To get 650 horse out of this 855 block you need to feed the fuel passage in the heads from both ends of the engine. The scored cylinder I believe is from a rolled O-ring from the lower liner packing seals of that cylinder. I believe area diesel services will do you right and helping you find a good CPL to build this motor to. There’s no reason you cannot build that block to a very nice 500 hp and it will live. There’s no such thing as bad engines it’s just bad mechanics.
8:16 😂
LOL!
He needs to find someone that knows what they are doing
Matt, As someone who spends about 99% of my time do things solo, I love watching you come up with solutions.
On the upside, at least you didn't just drop it in blind and immediately launch a piston. Looking forward to the progress!
i didn't realize how affordable the rebuild kits are, you could blow the 1500 relatively quick if you had to tow the truck, seems to me like cheap insurance/good content so the rebuild seems like the win
The thing has a standard intercooler, 650hp tuning will probably put the exhaust temperature through the roof, fry the valves and cook rings if the thing is held at peak torque for any length of time.
I think you should put the thing back to stock, but if you don't at least put a temperature gauge on the exhaust manifold and change down when it's getting hot. I wonder if the radiator will take all extra heat? The book figure for the 400hp is 9250 btu/min- 163kw to the radiator, probably twice the old small cam engine.
650 is well into K series territory, for that N's time.
Yah I don’t wanna set the world on fire just reliably haul stuff
You'll need to check the size of the air filter and exhaust muffler/silencer as well, air and exhaust flow are going up from small cam to 400hp big cam, and Cummins have limits on inlet suction at the turbo, and exhaust back pressure.
@@oldmuppet191I can personally attest that you want a set of mufflers on a BigCam 400. A buddy of mine had an Awefulcar (as he called it) Constructor with a Holmes 750 wrecker on the back that had straight pipes and going down the road without a load on it was painful to the ears but with a load and decelerating with the Jake’s on made sitting in the front row of a Who concert sound like a whisper
The issue with buying rollover engines is in many cases once a driver evacuates the vehicle they normally do not go back to shut them off! I have been early to a few truck crashes where you could hear the motors pooch themselves out. A few years back I witnessed a Cat bulldozer run rolled over for about 15 minutes before it went bang!
A farm tractor versus train crash I helped a towing company clean up, the engine was torn from other parts of the tractor, the engine was laying on its side running off crankcase oil getting in the turbo when the fire department got there. They turned it off with two dry chemical fire extinguishers in the turbo.
Ugly crash.
I sincerely hope you're ok Matt. We watch your content every single time. Missing you... Kentucky.
I'm sure you've heard of them but I think you could use a aqua blaster. Mr Hewes has just done a great video on how useful they are when working on large vehicles. The power of sandblasting with the convenience of a jet washer.
I'm very glad you referenced the Mr. Hewes Aqua Blaster video, I hope Matt checks it out.
The system shown on the video is probably one of the highest tech / highest cost option for Aqua Blasting. It's good to know that there are much cheaper option that simply attaches a syphon type nozzle to your existing power washer, they seems to work just a well as the high tech systems.
Example; ruclips.net/video/kfA-IkaMRGE/видео.html

Them big cams are hard to beat. “King of the highway” is what i was always told.
I like this old truck, and i would upgrade it to be a usable hauler to, because having it just parked to look at with a motor that can't work for you just makes it a lawn ornament. I'm looking forward to an older truck you've got parked to be restored. I know you have a better cab for the old girl, and having money and parts will help. That power company robbing you to get the power hooked up was a wallet buster, and then all the money to run power to the building added up quickly, plus the building and concrete wasn't cheap, so i get having to prioritize where the fund's go. G-d bless.
Well Matt, you know what they say - In for a penny - - - In for a pound (crap load of money)! !! !!!
Matt, you can do what you want, but if it was me, I would pull that crank, mich it and if the dimensions are good all the way down the line I would get it polished and go back together with it. Clean that blocks oil galleries good because they are how the metal got into those bearings. I would hate to spend that much money and time installing it and have some aggravating noise haunt me every time I go to start it and plan on a 600 mile trip. I like the ides of that old gal getting out on the road and can run with most of the trucks on it. You turn a lot of fuel in on the original engine and you're right, there will be spider webs all over those pistons. Like your videos.
I agree.
I rebuilt my big cam , and was amazed at the cost here in Uk , the cost compared to European engine rebuilds was way cheaper. Less that 50% ! The kit including oil , filters , exchange heads, injectors , the pump was rebuilt and upgraded , plus everything needed . I don’t know how much more it would cost now but I found the service I had from Cummins UK was second to none . I would recommend doing a full rebuild , it will pay in the long run .
Don't pull the cam unless you have access to the special tools to reset the cam follower boxes. Those boxes set the injection and valve timing and MUST be right. The gaskets for the follower boxes are actually shims and I would not feel comfortable just reusing the old shims. Who knows if the guy before you did it right?? I would guess the engine got hot, which is what ruins pistons and liners quickly. It looks like your engine is a Big Cam 3, which is good. The Big Cam 4 engine has a low-flow cooling system requiring a specific radiator. I found the Big Cam 4s to be very prone to overheating.
Beg or borrow the engine stand. It bolts to the side of the block and will make this job MUCH easier.
YES.
Follower alignment and spacing is CRITICAL in these applications.
It's not hard if you have the tooling, the procedure, and a touch of patience, but it is very important.
And yeah, a proper stand or, even better, rotator, would be near essential for an out-of-frame on one of these old gals.
I seen that the engine was going to fall, I yelled, I guess you didn't hear me. Also when working on something you want to save, be more careful of lifting apparatuses you use. When they slip result usually aren't pretty and are expensive. Pushing \lifting with Forks isn't real stable and when they slip they do alot of damage as you found out.
Love your videos!
BAD advice.
There most assuredly is metal scattered everywhere. ESPECIALLY in the cam bearings.
PULL THE CAM.
Will be stupid not to.
With Matt's contacts, someone has the tools and skills to get things set.
J.C.Smith just covered this on his channel. (Setting things, not my cam bearing statement).
When I first learned to drive I started using the approach to manual gear change we call "double de-clutching" which is to spin up the gearbox between changes so that you match the gears to engine revs giving any synchros an easy life. It became second nature and is the way I always drive. You may already do this bu if not - try it. In the early days, I practised when driving my employers vans, changing gear without use of the clutch at all once the van was moving. Great fun.
Sad to see she needs some loving but good to see you intend to give it to her. As others have mentioned, I'd consider knocking her down a bit to extend her life. Somewhere in the 500-525hp range should give you all the power you need, especially with the rear-end gearing it has without putting excessive stress on the ol girl. Can't wait to see her get fixed up and tearing that Autocar down the highway. 😁👍
Yah I’m fine with 450/500 even
@DieselCreek my ol man has an '86 Freightshaker tandem axle dump with a big cam in it and stock it has the power to take enough weight off the front end that it won't steer when loaded down and your foot on the floor 😂 it's only got an 8 speed Eaton in it too.
Hi matt when is the next video out it's been two weeks now I'm looking forward to the new video hopefully it will be soon
Bummer it's hurt alittle but it will be 100% when you are done. This truck has a special place in my heart you bought it from my very good Friend Brayden from Dying Bread Diesels. Can't wait to see her up and running.
Yup. He’s a good guy!
Im with masongillespie, im not a cummins expert but 650hp is much more power than i have heard if a big cam having much life. Glad tto here your making a teardown. I thing you will be happier where you plan on keeping the truck for a while. You might think about turning it back to 500hp or a little less. Good luck
Thank god you uploaded, I nearly had to go to rehab cause I hadn’t had a diesel creek fix.
One thing in cautious about a crash engine happened to my uncle. He had a driver roll a International with a V555 cummins he fitted new cab and straightened chassis but after that the 555 would loose oil pressure when run long enough to get oil hot and determined that it had an internal crash in block from crash. Was fine working local on stop start but go distance and oil pressure go buy buy
Those triple nickel engines are junk in trucks. Good in equipment but not over the road applications

You can change those crank bearings in the engine. Obviously, they didn't rebuild it fully. Maybe new pistons and rod bearings. Maybe a valve job but all done in the truck. The Babbit worn off the mains is old age, not from running upside down. Same with cly walls. That engine was not rebuilt, only patched up.
I would tend to agree with you.
Nothing better than Diesel Creek in the morning! Cheers from Canada.
650 Hp with a Big 400 Cam That is why them bearings look that way and also why the Piston Skirt Liner is gouged so bad on cylinder 1 looks like it was Starving for oil a bit if you Took 150 or so Horse Power out the motor And It was More like 400Hp the engine would Last Longer Have less problems.. That is A ton of power And Wear and tear on that 855 Cummings Block Matt 29:45 to 31:15 @Diesel Creek
Bummer! On the other hand, that's what you do - and, at the same time, share it with us! Thank you!
Mat, back in the '80s, I drove / operated a 330" wheel base Autocar gin pole truck for Lufkin pump jack repairs. It was a MONSTER. I miss those days, and we bought 242 Lufkin 360 pump jacks from a Phillips field in northern Oklahoma and disassembled and hauled 150 miles back to Oklahoma City at three a week. I drove a Mac R model to go and pick them up as well. I would piggy back two flat bed trailers to get to the location. We three people to do this task, I would start by hot wrenching all the nuts and bolts, then load on the trailers with the AJAX engine as well.
Would be cool to see a picture of that truck!
I love Autocar's! And especially love LONG Autocar's.
That's some cool history on that truck!!!!!
Always enjoy your detailed comments.
The Constructor is my favorite thing you own. I will be glad to see her on the road working again.
Awesome to have a new Video Matt! Marketplace is like a casino, always a gamble.
Funny you say that. I hate gambling, but I love buying cheap toys on marketplace.🤔
@@Happyfacehotwheels same lol
Hope everything is ok Matt! Been a while since a last upload!
I like the direction that you are going with this engine. In my view you too often want to 'luck out', whereas the most satisfying experience is when you do a righteous job, as you have set out to do on this machine. Plus there will be some personal growth and likely more viewers in this engine rebuild.
Sometimes the warranty on reputable engine rebuilder is the peace off mind we have been looking for
Sorry for the discovery on the engine Matt. Go borrow that engine stand, it will be worth the effort. I almost fell out of my chair when the engine slipped on the forks. Lol Ok, looks like there was a wood boiler sitting in the back of the truck parked next to where the Autocar was parked! Could it be? Looking forward to the rebuild. Thanks
Watching your vids have helped me keep my own project going. I am working on a 94 k2500 with a 6.5 turbo diesel and since I live in a cold place things have taken time. I have been close to giving up but thanks for inspiring me to keep going. I just need to be more patient and not stress, as it will take time to get it looking its best.
My project is a 95 k1500 with the 5.7, and I need to get back to it. I have a little more to do to get it on the road, I just need to do it. Good luck with your k2500. You'll be blowing black smoke in no time!😁
@@Happyfacehotwheels Thanks, I hope you g et your project done as well.
Hope you’re ok, Matt!
So cool to see this Rig Back For New goodies for the old Girl 0:50 @Diesel Creek
I would highly recommend replacing the crankshaft seals on the big cam engine while you’re in it. I didn’t on a S60 with similar history and have regretted it. Dripping leaks on a basically new motor gives everyone the wrong impression.
Super fan of your work, keep it up 🤠.
If you could determine if the seals were replace during the prior rebuild, you might be able to let it slide, but the chunky debris you’ve already found could also be trapped behind the sealing lips could cut the seals lifespan.
I vote for keeping some orange in the paint scheme.
This trucks ties to the Silver Spade is big. I’m real sure You understand the historical significance better than most people. I can understand why You want more speed and power. It would make a wonderful low boy tractor. If that big cam was mine, I would suggest line boring the main caps .
Excellent advice!
HEY Matt.. you good ? Havent seen a new vid in over a week.
I would do some careful measurements on that crank. Maybe someone did some home brew polishing on it and it is not sized correctly. Good luck Matt. Just do it all right and have a good engine that will last for a long time. Shoot…could even move it to another truck later if need be…so don’t worry about “wasting money” on it.
We had a big cam 350 that was turned up a bit in a spud truck. Also very low geared, but the Eaton Fuller 13 spd made it okay on the highway. Oddly enough, our Ford had the same winch. It was an oil field truck. With a 22’ self unloader, it was a great truck. It had the same Hendrickson walking beam suspension too. With those deep lugs and the walking beam, that thing will go almost anywhere!!!
Lol ... ambidextrous oil pan 😆🤣🤣
You probably meant reversible.
Great video!
Seeing that truck reminds me of the movie ‘Over the Top’..it looks like the truck that Hawk (Sylvester Stallone) drove.
Matt, I really enjoy your channel and all the growth in shop and equioment. Your mechanical know how amazes me. My Dad was a real mechanic, self taught and a deisel fleet mech. He was like you, he could make anything run.
