Lot of brainstorming over the years has led to beautiful workmanship and engineering. I am sure it will stand the test of time. And now, having done it once... Making a set of replacements.. Easy peasy! And I can relate to you in your statement regarding what kind of content we put out. When I was a young man I would watch shows like American Chopper, and BEG for SOMEONE to start a show like that for old tractors... Now, guys like you and I are making that dream a reality!

@@squatch253 Squatch, you are ahead of your time. We will look back and realize you were the pioneer. I do not miss a video. And when you pointed to Kyles channel I watched all of his videos in one setting. Let’s encourage more creators.
I wouldn't have wasted so many hours watching the dumb network sitcoms & dramas in the past if there had been content like this available to watch instead. 😉 🙂
RUclips has it's share of people slapping machines together as fast as possible for views, not because they care about them or plan on actually using them. Glad you are sticking to what makes your channel unique. That engine should work great, but even if it grenades it'll be good content at least 👍
Toby, I enjoy the technical details. I always chuckle when you say some comment about being a long video. It just means I have more time to escape into the rebuild world you are creating. I want you to give enough details at if I ever get the chance to rebuild one of these units in any capacity, I will be able to replicate the repair. Keep the details coming.
Im the first professional mechanic in my family, everyone else has been carpenters. Let me tell ya as someone whos interested in the old Cats and as someone who wants to start dabbling in them, this detail work is some quality stuff to watch.
You're never dull dry and boring. I'm always amazed at you're desire to get everything just as perfect as possible. Really enjoy watching and learning. Great videos.
Honestly, you didn't drag on there bud. Everything you're showing is brilliantly thought out and executed from the modifications, machine work, tool making, to the final assembly and every idea is applicable to anything a guy could be working on. I want a lathe and milling machine so bad it hurts LOL
I've never worked on a Cat, but when I need to fix a car, I find people like you on RUclips. Keep up the boring details. You never know when you might be helping some 75 yrs old 19 yr old figure out what to do. Engines are all basically pieces going around in circles and up and down. I get ideas from you that apply to Escorts and Hondas that may save me headaches down the road. Keep up the good work!
Will you please stop apologising for doing what you are doing. Love the technical, love the the long videos, love the getting your hands dirty. The only apology I would ever want from you is "Sorry guys, but I've had it with RUclips". ( DON'T EVEN THINK ABOUT IT!!!! )
@@squatch253 I'd just like to second what the neilshep said. It's your channel and it will run when you're ready for it to! Aswell as your content I've always admired your engagement with people in comments, I like how you'll give detailed responses to folks about their queries. You go far beyond what most you tubers do and I'd never considered that you'd be feeling pressure back to 'make it run'
Dude. You are completely successful with showing many of us best practices. I enjoy the Narrative, Tooling, and Technical details, etc. But above all, the majority of us understand how much work goes into making and sharing videos. And we understand that you don't have to share either. It's a privilege to watch you work and learn from your experience. I am amazed at how much I learn each week and how after its presented, I can say yup "I understand that and it was easy." But the truth is that you explain very well, and you make the complicated look easy. Your actions are a detailed demonstration of your intelligence, character, and desire to help. That is clear. You are making a difference in the world. It may seem like it's a small difference but it's larger than you can understand. My dad once explained to me that "Everyone has an opportunity to make a mark on the world. Some choose to barely scratch it but make it 100 miles long. Others make a mark that is deep but short..... The Deep Marks last the longest." Thank you sir.
Great speech at the end. My nineteen-year-old self would have eaten up advice from anyone who could have advised me through rebuilding old jeep engines and transmissions and transfer cases.
William Powell I enjoyed the rebuild of the pony Motor for the cat engine. I have never been around heavy equipment. I have enjoyed watching you completely rebuild the D2 cat. I mostly deal with the boating industry. What is the things that I rebuild on outboard motors lower units stern drives in car engines used in boats. I have installing A lot of cat diesels 6-8-12 cylinders in our yachts. I have always enjoyed rebuilding and repairing things since I was a young boy I am now retired 67 I am always watching stuff on RUclips that’s how I come across your channel keep up the good work enjoy it thanks Bill
You are making videos for 70 year old me. I love it. Because I understand building engines and machining it is easy for me to understand what you are doing. I love the detail. KO-KO
It's never dull or long winded for me. The Persian that you do. Absolutely love to see you put this back together. That's how my dad was . He was welder machest . He was an old railroader in the steam days. .
Thanks Squatch253 for all the detail. It is perfect. At 72 I have less knowledge than you did at 19, so I love you sharing your experience that I may learn possibilities that exist. The detail is appreciated. Keep up the good work.
Fantastic stuff Squatch. always amazes me that bearings like this can have such soft surfaces but at the same time cope with high loads. This is like being back at college in front of the Instructor!
I have no doubt the long-dead engineers who designed this starting engine system back in the day are wishing they thought of these innovations you are coming up with. Very satisfying watch! 😀👍
Keep up with all the information. It's instructional and educational. Since the beginning of the series, you've been in depth with what to look for, what's good and bad. This is better than instructions in a shop manual. You're showing how to make improvements and also showing what parts and seals can be upgraded or crossed over to.
Your so absolutely right. I'm learning 40 years of experiences in hours You're so detailed and explain it all so well. I'm so much better at knowing Cats for what you do.
That was pretty darn clever how you did that, your engineering skills are above and beyond. you have saved three starting motors. By the way your content is never boring and is always very informational.
Like Tato o said, I as well can’t wait for you to start the engine. it was a long time ago now when you was stripping parts off to make the engine light enough for the M to lift. I admire your work Squatch
Bombardier made 😁 a little bit of Canada in the shop. Not sure but from the back and hood looks like Nordic line. We had a Nordic 371E. four double tracks. A Olympic ski-doo. Ouch that was a long time ago.
You could avoid chamfering the bores edge by undercutting the inside corner of the flange on the bearing with a radius. For example take a triangular with 1/32 radius turning tool, touch the flange face and plunge into the bearings OD. This creates a corner that radiused about 90 degrees then tapers up by the angle (15° to 32° depending on how you set it) of the back side of your insert to the OD. I have seen this in several different applications, mainly in hydraulic cylinders ie rod stubs to clear pistons, wear ring grooves on pistons. Easy to do, and seems to stop cracking. Edit: but good job on how you have done it; the best solution is the one that works for you. I am enjoying all of your rebuild series.
Ooo!!! Great idea for the last of the try build!!! It's amazing how you make it look so easy. Glad you took us along with you on this build. Thanks for sharing....
I can already see the outcome of this rebuild. So much planning and drawing on past history of other engines this should work better than new. One of my life idols was a man who rebuilt motorcycle engines. His motto was that "it can always be rebuilt one more time". This is why I enjoy this series of videos. There is always a solution. So many pieces of industrial equipment, old tractors, engines etc. have been taken to the scrap yards. A throw away society we have become. I think that is due to the fact that no emphasis is put on saving equipment. Very possible it also means that there is not enough people who are in the repair business. (old school technology) In todays world it seems that everything is replaced rather than repaired. Great projects now, and I bet more will follow. Can't wait!!!
@@squatch253 Thanks for the comment. I had the same problem with radiator on my 460 utility. No new parts available. No used radiators available. Finally found the right person who knew what to do. Brother, it was not cheap. Throw enough money at any problem and it will go away. Same thing now applies to my health. Every day is a good day. Thanks again. Chuck
Just wanted to say that your content has great re-watchability. In between new upleads i've been watching your videos from two or three years ago, and i gotta say that their quality as well as contantce is still very satisfactory. Keep up the good work!
Very good! If nothing else you’ve demonstrated to all of us that where there’s a will there’s a way! I love all your videos and they’re never too long.
Squatch253, you have a most wonderful way of putting things over. I always look forward to a new episode and the small contribution I make to your channel is worth every penny. I do not own a tractor or indeed do any wrenching on vehicles at all these days and the last time I rebuilt an engine was in my youth (Ford Pinto block I believe you Americans class it!) some 48yrs ago. I do appreciate your work, time and effort and I would class what you have done with this Pony motor as advanced machining ... well done young man!
Thank you for this really educational presentation. No, it was not boring, on the contrary. A good thought, worthy of an engineer, excellently implemented in terms of craftsmanship. (Yes, and this from a German who always know everything better 🙄😂).
I also love the in depth technical aspects of this series. And the channels over all feeling and drive for exactitude. Sqautch not only does it well, and while explaining the thought process... while showing it all on video. Far better to show and explain as you go. Your basic level of expertise, level of tooling, level of obvious enjoyment in the subject is infectious. What a joy to watch along during the process, and for the quality end result. Well done as usual, Toby! Thanks
Your approach is inspiring my friend. Don’t apologise for the detail you go into. You’re creating a brilliant resource for others to use which will spur others along and help people save other machines. Chapeau sir!
Man I love what you’re doing, and I watch for the detail. I’d watch your episode if they were an hour long - you’ve got the pace, the level of detail, the level of explanation absolutely spot on. Just please keep doing what you’re doing and really - don’t worry !
Told my son to start following you... he is in his second week at Universal Technical Institute here in Rancho Cucamonga Ca. He is going to become a diesel mechanic
I like the tri-build series. Honestly I find this very interesting much more than the undercarriage work(to be fair Im a heavy equipment field mechanic and have done enough undercarriage work for 3 lifetimes). Now what we really need to see is a starting motor with electric start. Honestly I think thats the perfect setup. And yes I want to see how far that starter will move the Cat in gear. (I bet it will shock you).
This has to be one of (if not) THE best series on RUclips. Toby, been with ya since you and Senior loaded the D2 on a trailer. Keep up the great work and know some of us REALLY appreciate your attention to detail. I don't have a CAT and I'm not a mechanic by trade, BUT some of the thought process transfers into other fields that apply mechanical principals. Thanks again AND looking forward to Seniors Maple Syrup video 2022 :)
I have 2 pony motors. 1 running that I will be able to assess its condition better after watching your video. 1 that has sat out for years and is stuck. So now I will be able to refer to your videos if I get a little stuck. You saved 2 pony motors that might have otherwise been scraped. Who knows how many you saved buy anyone watching your video.
Very satisfying content! Well explained and demonstrated. Thank you! So much better than any reality show - I always got impatient because they never showed what they were doing. Instead they would waste time with apparent friction between team members blah blah. This channel has been something I can enjoy, seeing exactly what I wanted.
I'm not into crawlers or any type of tractors but it's mechanical and seeing this sure can help even on the automotive side. I sure enjoy watching this
I would like to see the guys face in the future who goes to work on that pony motor, looking at the cat repair manual and then at the motor. Definitely will be scratching his head for a while.
You are never dull or boring! I love all the content. The video is all good information, for someone to try to replicate that main bearing job with step missing would be twice as difficult. Great job, great video!
The "in the weeds" details are great and are part of what makes your channel unique. The chances of me ever owning a D2 are slim but your detailed presentation makes for must watch content.
I love that you aren’t afraid to try something new on a simple setup that allows for some modifications. My only initial concern would be wether or not you shifted the location of the rods and how they locate in the center of the cylinder bore. Though I assume they have enough movement in the pins to take up that small amount of offset. I like what you are doing and your brain seems to work like mine does.
I also love the technical aspect of your videos as it provides great insight on the restoration process. The gaskets you make always look as if they're die cut at the factory, great job! Do you have a previous video that shows how you accomplish making great gaskets? I'd like to see how an expert does it. Thanks!
I'm a casual observer and old mechanic. I love watching your work, you're a true craftsman. I now fine myself thinking about buying an old crawler. Just my 2 cents.
Great work so far! I started watching the channel by accident with episode 2 of 5J1113 and have been hooked ever since. As a “big kid” I still have the fascination with old iron but like many others I’m sure, I don’t have the space or tools to complete the work you are doing. What’s great about your channel is you never come off sounding like hey look at me and my collections of tractors or tools of skills which is a testament to the great work you are doing. Can’t wait to see this old girl fire up!
Been watching this project for a while and you are doing it better than I could ever dream of. Just watching this episode with a couple of "refreshing beverages" I was thinken how about using needle bearings on the mains. Just interested in your thaughts on this idea.
Hi Toby, I often comment on the ethos you follow with the restorations. This one is more about experimental engineering and that's a valid approach as well. The side force theory is good, of course, it's coming from you, and should greatly extend operational life but will you ever know it really works in the long term? These machines are unlikely to be anything like as heavily used in the future as they were in the past, so you are not doing this for yourself, or even your contemporaries. It's a gift to the future and good on you for doing it. Fully justified in my eyes. Cheers.
When I retired and canceled my directv I was using you tube to help with some things I needed to do. Then I started looking into things I was curious about. That's when I found your channel and some others. Seeing the details and problem solving and other people's skills makes it fun and interesting. Just went and checked out your friends rd-4 project and that looks like a bold task ahead. This stuff is better than Hollywood or overpaid politicians and sport egos. You may need to make an appearance on your friends channel just for grins!
I dont know where you learned engineering but you are spot on . even in welding hull patches to a dozer bucket patch you want rounded corners even a patch in a pressure vessel
Too detailed and in depth can never go wrong! Those who don't like it may skip it, thats the beauty with youtube. It's hard for us who likes it to add it if it wasn't there :)
Awesome video it's nice to see how you the bearing thrust surfaces figured out the technical aspect is the most interesting part of the build by doing machining and reworking parts that even caterpillar did not even go that far to correct the failures. Now you can repair as many blocks as you wish too tackle when you have all the right tools. Keep up the great videos 👍👍👍👍
Enjoy very much what you are doing. You have saved an engine block from the scrap heap and I look forward to more well thought out repairs. Thanks for the video.
Great content! I enjoy the in depth explanation and the realistic and down to earth solutions. I'm not a CAT owner but your projects cross over to many other things. Thanks!
Love the technical stuff and the clear understandable camera shots and the hand drawings help you understand the hows and whys, great work keep it up....thanks
The sign of a true craftsman. Taking something that was good and making it better. Would you mind taking a look at the surgeons notes on my first knee replacement and making recommendations for improvement on the next one?! 😂 Seriously though, nice work!
Toby, thanks for saving my evening! I was searching for anything new within my RUclips subscriptions for something interesting. I've watched all my regular channels previously and was getting bored. Was hoping to find something techie, and WHAM, your latest video popped up to save the evening. Thank you!
Squath, I have enjoyed all of your videos, even the farming ones and the brush clearing ones. I do not have a dozer and probably never will but I have 10 old two cylinder John Deere tractors, one Allis Chamber and one Oliver 88 tractor, all of which I overhaul and maintain. I have 6 old air cooled two cylinder Volkswagen sedans, of which I have 3 in running and driving condition and I have 6 motorcycles, 3 Hondas, 1 Harley Davidson, 1 Suzuki boulevard, 1 Yamaha road star, 1 Cushman Eagle that I put a V-twin 18hp Briggs & Stratton engine in and 1 Bonanza mini bike. You can tell I love mechanicing and machine work.
I found the tri build series to be wonderful and this one slightly more than the others since your trying a new idea to remove some of the load on those bearings, I like the idea, not that it means anything good or bad, I just like that you thought this out and came up with a solution the factory didn’t think of. Excellent work there young man.
Thanks for the Kyle video channel reference - I will never be as exact as you but I aspire to be Kyle chisel to separate parts Check yep I have done that My own private Acetylene torch for all fastener removal - I paid my way thru University of Wisconsin fixing British sports cars exposed to salt so hell yeah soaking a part and waiting a week - not in my vocabulary but I am learning
Excellent content as usual! One thing to think about is that the crankshaft will grow in length as it heats up (0.0000058 inches/inch DegF) and the original distance between thrust faces would increase by ~ 0.0014" (assuming 2" journal length with 120 DegF increase in temp). Your new configuration would DECREASE by ~0.0042" (assuming 6" between thrust bearing faces with the same 120 DegF temperature rise). With a bronze or tri-metal bearing this may be tolerable, Aluminum bearings are very sensitive to increases in operating temperature since they EXPAND about 2.5 times as much as iron does for a given temperature rise. While it is entirely possible that your engine will be fine, you will be running with significantly less thrust clearance than originally designed. I recommend that you set your thrust clearance toward the large end of the spec to assure that things don't bind up when it gets hot.
21 year old me sure appreciates what you do here, Squatch. This channel was an absolute godsend for me. I've enjoyed everything you've put up on your channel, but I have been particularly anxious for the starting engine build(s). I'm trying to keep my poor D4 running, and every bit of information helps. Especially being able to see how the starting engine looks when it's opened up, and also knowing about the common problems. You do an excellent job of explaining things. Does it get meticulous sometimes? Yeah. But sometimes that is necessary to get the point across. First video of yours I ever watched was how to start a D2/D4. I would never have known to shut the gas off to kill the pony motor, if not for you. Thank goodness I picked that tip up, or I'd have a shot crawler right now. Looking forward to the next episode, as always!
I had to tear down an air compressor (10 hp Kellog American) and was surprised to see the rebuild kit with something like 10 gaskets on the crank end cap. Ok, pretty strange but the tapered roller bearings were destroyed, hmmm. So, trial fit with one gasket and the thing is locked up. Add more gaskets and I have used all the new kit gaskets and its still locked up. The light is coming on, it was put together and was tight with no end play, ergo, the destroyed bearings. Being all out of new gaskets I start stacking in old gaskets and used 3 or 4 of those. Now those were compressed but it took that much to get the spec end play on the crank. First start ups must have been interesting as it simply ground in to end play and lasted 20 years (no, they did not maint on it)

Squatch253, you have a most wonderful way of putting things over. I always look forward to a new episode and the small contribution I make to your channel is worth every penny. I do not own a tractor or indeed do any wrenching on vehicles at all these days and the last time I rebuilt an engine was in my youth (Ford Pinto block I believe you Americans class it!) some 48yrs ago. I do appreciate your work, time and effort and I would class what you have done with this Pony motor as advanced machining ... well done young man!
Thank you for this really educational presentation. No, it was not boring, on the contrary. A good thought, worthy of an engineer, excellently implemented in terms of craftsmanship. (Yes, and this from a German who always know everything better 🙄😂).
I also love the in depth technical aspects of this series. And the channels over all feeling and drive for exactitude. Sqautch not only does it well, and while explaining the thought process... while showing it all on video. Far better to show and explain as you go. Your basic level of expertise, level of tooling, level of obvious enjoyment in the subject is infectious. What a joy to watch along during the process, and for the quality end result. Well done as usual, Toby! Thanks
FYI, over on the Members feed, you get even more insight into his thinking and overall approach. I have always found that part most compelling.
I'm really not so into tractors, but the way you explain everything and find solutions. I'm looking forward to every episode!
Your approach is inspiring my friend. Don’t apologise for the detail you go into. You’re creating a brilliant resource for others to use which will spur others along and help people save other machines. Chapeau sir!
You and Senior rock with your attention to detail and knowledge of mechanical devices. 👍😎
I'm impressed with the thought process and skills you have to make these repairs.
I’ve been following this Build from the beginning, definitely enjoy all the technical aspects of your videos!!
Man I love what you’re doing, and I watch for the detail. I’d watch your episode if they were an hour long - you’ve got the pace, the level of detail, the level of explanation absolutely spot on. Just please keep doing what you’re doing and really - don’t worry !
Wizardry at its finest. Lots of thought and study went into this upgrade.
Looking forward to seeing the running engine.
Thanks for sharing.
Told my son to start following you... he is in his second week at Universal Technical Institute here in Rancho Cucamonga Ca. He is going to become a diesel mechanic
I like the tri-build series. Honestly I find this very interesting much more than the undercarriage work(to be fair Im a heavy equipment field mechanic and have done enough undercarriage work for 3 lifetimes). Now what we really need to see is a starting motor with electric start. Honestly I think thats the perfect setup. And yes I want to see how far that starter will move the Cat in gear. (I bet it will shock you).
This has to be one of (if not) THE best series on RUclips. Toby, been with ya since you and Senior loaded the D2 on a trailer. Keep up the great work and know some of us REALLY appreciate your attention to detail. I don't have a CAT and I'm not a mechanic by trade, BUT some of the thought process transfers into other fields that apply mechanical principals. Thanks again AND looking forward to Seniors Maple Syrup video 2022 :)
I have 2 pony motors. 1 running that I will be able to assess its condition better after watching your video. 1 that has sat out for years and is stuck. So now I will be able to refer to your videos if I get a little stuck. You saved 2 pony motors that might have otherwise been scraped. Who knows how many you saved buy anyone watching your video.
Thanks Toby for taking us along on this work around been waiting for a while.
Very satisfying content! Well explained and demonstrated. Thank you! So much better than any reality show - I always got impatient because they never showed what they were doing. Instead they would waste time with apparent friction between team members blah blah.
This channel has been something I can enjoy, seeing exactly what I wanted.
I'm not into crawlers or any type of tractors but it's mechanical and seeing this sure can help even on the automotive side. I sure enjoy watching this
I would like to see the guys face in the future who goes to work on that pony motor, looking at the cat repair manual and then at the motor. Definitely will be scratching his head for a while.
You are never dull or boring! I love all the content. The video is all good information, for someone to try to replicate that main bearing job with step missing would be twice as difficult. Great job, great video!
Wow a fine tuned start or pony engine by Squatch who is more then qualified to super tune or blueprint most engines.
The "in the weeds" details are great and are part of what makes your channel unique. The chances of me ever owning a D2 are slim but your detailed presentation makes for must watch content.
Amazing! I am not a machinist but I have not seen a key slot hammered in. I love it! Necessity is the master of invention. Love, love this channel.
Another fantastic film. None of these are boring. (I watched all of the foldover washer film)
You sir are a very talented man. Great ideas, nice workmanship. You should be very proud of your accomplishments. Very fun to watch keep em comin.
Ramble all you want! I'll watch!
I love that you aren’t afraid to try something new on a simple setup that allows for some modifications. My only initial concern would be wether or not you shifted the location of the rods and how they locate in the center of the cylinder bore. Though I assume they have enough movement in the pins to take up that small amount of offset. I like what you are doing and your brain seems to work like mine does.
Squatch? No! From now on you are Herr Doktor Frankenpillar. When I hear that pony run I will be shouting , "It's alive! It's alive!"
I also love the technical aspect of your videos as it provides great insight on the restoration process. The gaskets you make always look as if they're die cut at the factory, great job! Do you have a previous video that shows how you accomplish making great gaskets? I'd like to see how an expert does it. Thanks!
You and your work just amaze me!! Just so intriguing and interesting to watch, I learn something every time I watch a video of yours!! 👍
I'm a casual observer and old mechanic. I love watching your work, you're a true craftsman. I now fine myself thinking about buying an old crawler. Just my 2 cents.
Great work so far! I started watching the channel by accident with episode 2 of 5J1113 and have been hooked ever since. As a “big kid” I still have the fascination with old iron but like many others I’m sure, I don’t have the space or tools to complete the work you are doing. What’s great about your channel is you never come off sounding like hey look at me and my collections of tractors or tools of skills which is a testament to the great work you are doing. Can’t wait to see this old girl fire up!
You are a thinker, planner, much admired..
Been watching this project for a while and you are doing it better than I could ever dream of.
Just watching this episode with a couple of "refreshing beverages" I was thinken how about using needle bearings on the mains.
Just interested in your thaughts on this idea.
Hi Toby, I often comment on the ethos you follow with the restorations. This one is more about experimental engineering and that's a valid approach as well. The side force theory is good, of course, it's coming from you, and should greatly extend operational life but will you ever know it really works in the long term? These machines are unlikely to be anything like as heavily used in the future as they were in the past, so you are not doing this for yourself, or even your contemporaries. It's a gift to the future and good on you for doing it. Fully justified in my eyes. Cheers.
When I retired and canceled my directv I was using you tube to help with some things I needed to do. Then I started looking into things I was curious about. That's when I found your channel and some others. Seeing the details and problem solving and other people's skills makes it fun and interesting. Just went and checked out your friends rd-4 project and that looks like a bold task ahead. This stuff is better than Hollywood or overpaid politicians and sport egos. You may need to make an appearance on your friends channel just for grins!
I dont know where you learned engineering but you are spot on . even in welding hull patches to a dozer bucket patch you want rounded corners even a patch in a pressure vessel
Squatch, have you considered making a video of all the tools you have built for 1113?
Too detailed and in depth can never go wrong! Those who don't like it may skip it, thats the beauty with youtube. It's hard for us who likes it to add it if it wasn't there :)
Awesome video it's nice to see how you the bearing thrust surfaces figured out the technical aspect is the most interesting part of the build by doing machining and reworking parts that even caterpillar did not even go that far to correct the failures. Now you can repair as many blocks as you wish too tackle when you have all the right tools. Keep up the great videos 👍👍👍👍
Satisfying watching the step cutting - thank you for sharing, your explanation and narration is excellent!
Enjoy very much what you are doing. You have saved an engine block from the scrap heap and I look forward to more well thought out repairs. Thanks for the video.
Great content! I enjoy the in depth explanation and the realistic and down to earth solutions. I'm not a CAT owner but your projects cross over to many other things. Thanks!
Love the technical stuff and the clear understandable camera shots and the hand drawings help you understand the hows and whys, great work keep it up....thanks
The sign of a true craftsman. Taking something that was good and making it better. Would you mind taking a look at the surgeons notes on my first knee replacement and making recommendations for improvement on the next one?! 😂 Seriously though, nice work!
Radiusing the corner is something I would never thought of.
Toby, thanks for saving my evening! I was searching for anything new within my RUclips subscriptions for something interesting. I've watched all my regular channels previously and was getting bored. Was hoping to find something techie, and WHAM, your latest video popped up to save the evening. Thank you!
Squath, I have enjoyed all of your videos, even the farming ones and the brush clearing ones. I do not have a dozer and probably never will but I have 10 old two cylinder John Deere tractors, one Allis Chamber and one Oliver 88 tractor, all of which
I overhaul and maintain. I have 6 old air cooled two cylinder Volkswagen sedans, of which I have 3 in running and driving condition and I have 6 motorcycles, 3 Hondas, 1 Harley Davidson, 1 Suzuki boulevard, 1 Yamaha road star, 1 Cushman Eagle that I put a V-twin 18hp Briggs & Stratton engine in and 1 Bonanza mini bike. You can tell I love mechanicing and machine work.
Two cylinder Volkswagen sedans????
@@erik_dk842 I ment to say air cooled 4 cylinder VWs.
I found the tri build series to be wonderful and this one slightly more than the others since your trying a new idea to remove some of the load on those bearings, I like the idea, not that it means anything good or bad, I just like that you thought this out and came up with a solution the factory didn’t think of. Excellent work there young man.
I really appreciate the amount of time and detail put into your episodes. Its somehow very soothing watching you work. Thanks for the knowledge!
Squatch - Koodos sir! Manual milling. WOW! No doubt about it. You are the "Fiz" sir! Hats off to you!
Thanks for the Kyle video channel reference - I will never be as exact as you but I aspire to be Kyle chisel to separate parts Check yep I have done that My own private Acetylene torch for all fastener removal - I paid my way thru University of Wisconsin fixing British sports cars exposed to salt so hell yeah soaking a part and waiting a week - not in my vocabulary but I am learning
Technical stuff is good . Most people don't realize all the steps that are involved in rebuilding equipment like this.
I do like the technical stuff and enjoy seeing your engineering solutions!
Excellent content as usual! One thing to think about is that the crankshaft will grow in length as it heats up (0.0000058 inches/inch DegF) and the original distance between thrust faces would increase by ~ 0.0014" (assuming 2" journal length with 120 DegF increase in temp). Your new configuration would DECREASE by ~0.0042" (assuming 6" between thrust bearing faces with the same 120 DegF temperature rise). With a bronze or tri-metal bearing this may be tolerable, Aluminum bearings are very sensitive to increases in operating temperature since they EXPAND about 2.5 times as much as iron does for a given temperature rise. While it is entirely possible that your engine will be fine, you will be running with significantly less thrust clearance than originally designed. I recommend that you set your thrust clearance toward the large end of the spec to assure that things don't bind up when it gets hot.
Think about that poor wrench head who tears that last block down and try’s to get bearings. Great stuff
@@squatch253 It was meant to be positive compliment .
Stunning D2 series over the past years, watched all so far
Two thumbs up for all the details. Keep ‘em coming. You do great work.
@@squatch253 patience is a virtue, and good things come to those who wait 😉
@@squatch253 I'm sure it'll run when it's ready to run. Me, I can wait till then!
Great insight to irts design and your modifications to overcome the issues with each engine, a fine body of work , well done a credit to you 👍
21 year old me sure appreciates what you do here, Squatch. This channel was an absolute godsend for me. I've enjoyed everything you've put up on your channel, but I have been particularly anxious for the starting engine build(s). I'm trying to keep my poor D4 running, and every bit of information helps. Especially being able to see how the starting engine looks when it's opened up, and also knowing about the common problems.
You do an excellent job of explaining things. Does it get meticulous sometimes? Yeah. But sometimes that is necessary to get the point across.
First video of yours I ever watched was how to start a D2/D4. I would never have known to shut the gas off to kill the pony motor, if not for you. Thank goodness I picked that tip up, or I'd have a shot crawler right now.
Looking forward to the next episode, as always!
This is the meat and taters of the working motor! Very interesting and tech savvy! Keep tracking!
I had to tear down an air compressor (10 hp Kellog American) and was surprised to see the rebuild kit with something like 10 gaskets on the crank end cap. Ok, pretty strange but the tapered roller bearings were destroyed, hmmm. So, trial fit with one gasket and the thing is locked up. Add more gaskets and I have used all the new kit gaskets and its still locked up. The light is coming on, it was put together and was tight with no end play, ergo, the destroyed bearings. Being all out of new gaskets I start stacking in old gaskets and used 3 or 4 of those. Now those were compressed but it took that much to get the spec end play on the crank. First start ups must have been interesting as it simply ground in to end play and lasted 20 years (no, they did not maint on it)
