Caterpillar D2

[@pinwizz69]

Your professionalism about how you go about describing your preparation, testing, lubricating, locating and installing all the parts you put together is absolutely outstanding. Pretty much every vocational school in America and abroad would love to have you as there top instructor. I was lucky to have one of your caliber my Junior and senior years of high school afternoon classes at Flint Michigan's Gennesse Area Vocational School small engine repair class (anything under 12 hindred CC for some reason, motorcycles I guess) and it's one if the reasons the Coast Guard offered me guaranteed A school if I swore in on delayed enlistment status. I got bummed up from a year and a half post Vietnam RIF waiting list to reporting to boot cam in 7 months. Then I got the school I wanted, Aviation Machinist Mate A school. All thanks to an instructor of your caliber. He was a short 5'5" red headed gentleman originally from Boston and we called him the Boston Terrier. Make a mistake abd he'd seriously let you know you did. One of our first classroom sessions was proper use of tools. He took out a junked Briggs and Stratton engine. Set it up on his big military surplus desk and began smashing it to pieces telling us "This is not how you use a hammer". Then he started showing abd explaining various tools abd the proper way to use them. One guy had been falling asleep till he banged the crap outta that engine. We were wide awake after that little demonstration.

Hi Toby. I think of these lovely old machines as works of art. Mechanical jewellry. I like this style of American engineering as well. Solid, robust, designed to last. It's a pleasure watching a deeply caring and higly skilled person bringing this engineering history back to life. A big manly hug! BobUK.

[@MatthewBerginGarage]

Looks like the passage in the idler hub works the same as the drip traps on the NG lines or the sludge trap in my Triumph's crankshaft. I also like to enjoy the beautiful engineering solutions these old designers thought up. The designs are just so clean and concise.👍😎

Nice to watch a real mechanic (not just a parts changer) work

[@bobcrone6151]

Man this series makes me wanna go down to the community college and sign up for a basic diesel mechanic class and take it from there! And I’m 60 years old!🤣 Amazing series. My favorite project on here!👍👍👍

[@BobPegram]

Excuse my lousy sense of humor, but if you were "Bobbie Crone" and unmarried your last name would fit you perfectly!

[@tractorhyatt7044]

I am with you on that. Sign me up too! 🚜👍

[@sterlingwilkey2124]

Sir go for it what will it hurt not one dang thing

[@jimb6117]

You would get thrown out for being a know all mate because the teacher would not be up to standard and you would have to correct him on many thing's.

[@skylinefever]

@@jimb6117 I got in trouble a few times because of that. It was 2006, and I was 22. The teachers were in their late 50s. The one I remember most happened in air conditioning repair class. I wasn't in diesel repair class, I was in auto repair. A few days before the incident, a Dodge Ram CTD 24V came to our class with an A/C system that wasn't cold enough. This was the type built between 1998 and 2002. Once we did tests, replaced the fan clutch, fan belt, and recharged the refrigerant, it blew cold. A few days later, when the teacher was pointing out how the A/C condenser is in front of the other heat exchangers. He asked "So are all vehicles like this?" I said "No. The diesel our class worked on had the intercooler in front of the A/C condenser." He was pissed. Even if I didn't bring that up, I still would have corrected him. I would get a photo of a Mitsubishi Lancer Evo VIII and show him the intercooler. I know the Mitsubishi Evo went on sale in the USA after he left the repair business and became a teacher. He was a huge Toyota guy, so I don't think he would have ever have noticed or read about a Mitsubishi Evo VIII. For people who never heard much about rally cars, these cars often go unnoticed. Many look like economy cars with fancy bodywork attached. I do think I said something that made him happy, however. In 2006, I think most gamers knew what a Skyline GT-R was, but the older generation did not. What I said was "One reason this car was great because the engine is similar to that of a MKIV Supra Twin Turbo" I think that sounded good to a fan of Toyotas. It was probably the last good looking and fun to drive Toyota.

[@dwayneshelton9306]

As always love the old machines and how they were put together to last.

[@pinwizz69]

Nothing wrong with draggin' on your episodes Toby. We subs get so fascinated by your methods and explanations we'd continue watching if it was another 10 to 20 minutes long. I'm pretty sure that my fellow subs feel the same way. Now on to the next episode. I'm slowly out of sync getting caught up on the history of this build.

[@tractorhyatt7044]

Thank you for another quality video, Squatch! Have you ever thought about teaching shop in a high school or machinery mechanics at a technical school? You have an amazing gift of teaching, just like your dad! 🚜👍

[@tractorhyatt7044]

I understand. Keep on doing what you are doing. You are still teaching many of us through your channel. Thank you!

[@BobPegram]

@@squatch253 You are perfect for distance learning Squatch253! Train in the local helper teachers well. Answer the persistent student questions yourself. You are already doing this, just fit what you are doing for fun into a curriculum for the kids.

[@lukestrasser]

Nice long 5J1113 video for a Wednesday evening! I really appreciate you taking the time to disassemble spare D3400 components to use for show and tell. The bushing in that accessory hub is impressive! I mean, what a work of mechanical art, the beautiful spiral groove, the contrasting colors of bronze/brass and steel, just incredible. I really appreciate how thick the bushings are as well, 3/16" or better it looks like. The use of so much brass/bronze/copper in the engines is really incredible. I just love old equipment where the thought of light weight castings and thin bushings of the weight and cost saving era had not yet crept in. Fantastic work Squatch. Hope all is well, second batch of Japanese Kit Kat's have landed at the Bork farm, labeled this time. Hopefully Rick didn't switch the labels around on you. Keep up the great work.

[@lukestrasser]

@@squatch253 I'm excited to see more beautiful cast bronze parts going in the engine. I'm assuming you'll be using the suction bells and tubing from 5J2115 SP since they were in such nice shape when you disassembled it. If so, I'm happy to see more parts from that machine will live on in 5J1113! Not sure if you've seen my other comments back and forth with Shane and Rick, it was never my intention for any of the 3 of you to feel obligated to do anything on KZbin, I know the last video didn't do well on your channel at all, and the last thing I want is to negatively affect your channel growth. My intent was more to share some of the more bizarre candy flavors, with full expectation that the majority of them would wind up in the break room at work for some unsuspecting coworker to try. I promise none are foul or dreadful, but some I didn't want more than 1. However I did label all of them for what they are this time. That's a lot of words just to say, don't feel any obligation to take time out of your busy schedule to make a video on my behalf.

[@skylinefever]

@@lukestrasser I really enjoyed when you gave those Japanese snacks to the hosts of this channel.

[@johnleake708]

Thank you very much for taking the time and making the effort to record your videos, I watch everyone I can. You and your father are very good at explaining how things assemble and work.

[@volvoguy76]

Thanks again! Your channel is so inspiring. You and your Father have have opened up a whole new mechanical landscape, I think for a lot of people. I work almost entirely with older Volvos, but now I want a Farmall H or M. A CAT is a little outside of what I could get away with. That said, I *love* seeing oil pressure feeds from the block through tubing into other components. I'm hoping to get involved with vintage machinery clubs, but there's nothing really in my neck of the woods.

[@PRRGG1]

Great visit tonight. Sneaky little fold over locks, those are an art form for sure. Glad to see you and Senior survived the snow.

[@dieselmann34]

As a heavy truck diesel mechanic. I appreciate seeing the care taken. While building this engine. Great job Squatch253.

[@paulhammond7489]

Loving the old iron and the design that permits rebuilds

[@skylinefever]

It is great that the design was made to be rebuildable, but I find videos of people saving throwaway engines to be even more fascinating.

[@chrisskelhorn5727]

How come my tutors were never like you? They knew what they were doing, but their 'people skills' needed a LOT of brushing up! Consequently, I think I've learned more in your videos that I did than 4 years of college! :-O Excellent vid Squatch, kudos to you, and thank you for sharing! :-)

[@thomasmarion3209]

I am glad you showed fold over locks in tight spots I wonder myself thanks 👍👍excited to see it all come together 👍👍🚜

[@_P0tat07_]

It is pretty amazing how they accomplished machining like that 80 years ago. I bet they had an fourth axis attachment for their mill that would be driven by the mill itself a geared to turn at the specific pitch while down feeding. Pretty neat stuff, we have a really old horizontal milling machine at school that basically has a PTO for running attachments in that exact purpose.

[@hfdzl]

Most all the gears were cut on a gear hobbing machine.

[@_P0tat07_]

hfdzl ik talking about the spiral oil passing in the bushing

[@rodneymiddleton9624]

Such precision engineering and design. Very impressive. Can't wait to hear the old girl run again.

[@isbcornbinder]

This engine is not "an old girl." It is the matter of the camshaft. All girl engines are two stroke.

Great video! I knew the air would be whistling through the oil passage. You have incredible attention to detail & patience. Looking forward to the next installment!

[@tracywraley6892]

The paper gasket could be a shim for the accretion shaft to give clearance for the fuel pump

[@j.b.maxwell8300]

Squatch why didn’t you torque that bolt under the lock you were showing then take the bolt around enough to align the lock tab, that was way I was taught to do it and I have done oodles like that since and not one bolt failure ,especially important with multi tab locks, I love the way you are teaching assembly of the engine to viewers to show the cleanliness of parts you use old or new and that last minute inspection you do of every thing including the work area, top job thank you

[@waynegotthardt3233]

Another great video! My thought on the Three Hole Mystery Gasket is. The fourth hole may be to seal the oil passage to eliminate any leakage between the casting faces. I may be all wrong if there is no Gasket provision on the other side of the Housing Cover.

[@johnnymac1580]

Every component is a marvel of engineering, all without computers

[@haydenc2742]

Starting to look like an engine! Woo! Can't wait to see it making smoke and doin' work!

[@creepy013]

Hi Squatch, thank you for a great video, I'm not sure but I think that unknown gasket may be there to help maintain oil pressure ie, stop oil under pressure from entering the rear drive section. When oil comes out of the triangle piece it can only go forward, but this only a guess. Cheers Gary

[@Mmmyess]

Now my ignorance has been exposed to the rest of the Squatch crowd. :) Thanks for the illustration. I never would have guessed that you use a 90-degree screwdriver. I actually didn't know such a tool existed. (Learn something new every day, I s'pose.) Seeing how you bent up the tab raised another question: How did you do that with the fold over washers behind the accessory shaft??? (Also, why no gasket goo on the mystery triangular gasket?) The questions never end...

[@hopelessnerd6677]

No hideous music, superb video quality, and great content. No need to watch any other videos for any reason whatsoever. ;-)

[@ac170]

[@cassiuspuckett8789]

It's beginning to look like a Cat engine!!! So far so good. Nice video Toby......

[@jasonwhitler4167]

I'd guess the gasket is probably used as a shim for some reason. Maybe it pushes the accessory shaft gear into alignment with the idler.

[@Spud_Wrench]

Love the engine rebuild series great to see the old iron coming back to life. Just curious if you have much experience with aftermarket overhaul kit's if you could do a video on preferred engine overhaul kit's and your experience that would be great!

Nice! Thanks for sharing! I'm still working on getting the pole barn tin on my old chicken house. Doing the gable end now. I sit and lament about how to get the right angle on the cut that goes up under the J-channel. Sure not the same thing you are doing here but I feel it all comes down to common sense like your locks as an example. After a while both our projects are coming together. Yours looks a lot better and will have a lot more power than my project. But mine will keep my old tractors out of the weather.

Oil grooves are simple with the right machine. Many years ago I was a partner in an engineering company here in South Africa. Amongst the contracts we had was one with CAT and another with Furukawa. Manufacturing spare parts. We had a special (but very simple) machine for doing oil grooves - all cam operated. You just dialled in the groove dimensions you wanted & pressed the start button. A few seconds later you had your part. No skill required.

The bolt thread looks quite coarse, what threads are used on these old US engines? I'm from UK and BSW & BSF would have been common around this era.This old engine is beautifully made and a great testament to the guys at Cat.

[@joekahno]

I thought you already did a really good job of explaining the fold over locks. What I'm curious about is how you got them bent so neatly working through the access holes in the gears. Is there clearance to get behind them with a punch?

[@codybrown9600]

I can’t wait to see it painted.

[@KennyKizzleRustyNutzRanch]

Great video, bud. I am hoping to get in the garage this weekend. Great tutorial on lock tabs as well. You did cover it quite a bit in one of your recent previous videos... Never hurts to have a refresher. With that gasket - could it be acting as a shim? Generally they are made of metal but I've seen them made from paper before. Just a thought.

[@KennyKizzleRustyNutzRanch]

@@squatch253 I'm running into the same issues with some cork gaskets I found inside the trans on the H... Can't find them on parts diagrams anywhere, but they were in there so I am thinking I will make new ones and use them when reassembling.

[@RGC1968]

Heyyy Squatch. Love your video's!! Just had a thought. The old gasket for the accessory shaft has the part number on it. The gasket you made....does not?? As I know you are more then likely to write the part number down in your journal. Would it not also be a good idea to write the part number on your home made gasket as well. Just like Cat did??….Richard

[@billtheunjust]

I wonder if the paper gasket is acting more like a shim?

[@mjp5429]

The design of the fly weights is not that far removed from a steam engine.

Good show! Thanks

[@clydebalcom8252]

[@seniorelectrician6831]

[@casparberends2719]

Maybe the paper gasket acts as a shim to move the gear somewhat?

[@daningrim475]

Great video! Just curious though--you show the reason to clean out the sludge out of the low flow areas in the lubrication of the idler gear but not seem be equally concerned about the need for disassembly to perform the same task for the shaft and lubrication pathway to the bearing for the accessory gear. Wouldn't the narrowed pathway, (which I would think would be low flow as well), through the accessory gear shaft fill with debris over time too?

[@jankotze1959]

Good episode

[@robertquast9684]

Pretty amazing that it was all done without fancy Cnc machines and computers

[@mattprater7184]

i just watched your video and was thinking about that gasket for the hub mount for your accessories drive maybe it is used as a shim more than a gasket and i am enjoying the videos

[@00nutt]

Looking good squatch!!!!

[@joelmollenkopf3767]

Excellent My question is why don't they use hydraulic lifters on diesels today?

[@skylinefever]

In some cases, solid lifters are used on modern diesels because they don't go out of lash specification between rebuilds. I think you can partially thank: 1. Modern oils 2. Modern filters 3. Modern materials 4. More accurate measurements. Also, with SOHC and DOHC engines, not having hydraulic parts has been extremely common.

[@themajority5716]

Just awesome!! Thank you!!!

[@BobPegram]

You contemplate slick machining like the spiral machined into the bushing? Go watch some machinists who do machining by hand. I recommend Keith Rucker of Vintage Machinery as a start. He might well have made something like that bushing.

[@BobPegram]

@@squatch253 I think You Tube is an excellent way to inform and teach people. Budget in an hour or so a week to watch how other people solve problems you are having or to see how other specialists work.

There is no worry of downward-facing tapered pipe threads loosening from vibration and pressure?

[@alanharney5278]

Squatch, are fold over locks common in modern diesel or gas engines?

[@54321danfox]

Thanks again for another good video. I always learn something. Thanks also for the patient explanation of the fold-over locks. If you get another opportunity to show us how one of those might be installed _through a hole in a covering assembly like a gear_, I would be very interested. I just don't see how to bend one up and/or down while it's at the bottom of a hole.

[@paszkors]

Outstanding content. Jumping ahead, when do you anticipate reinstalling this engine?

[@waynep343]

do the gear teeth just get splash lubed or is there a nozzle someplace that lubes them.

[@jerryhill681]

They may have encountered wear between the two parts prompting the gasket to prevent fretting.p

[@morgansword]

I hear a walking talking "cat manual"... when fossil fuel is no longer available and they make fuel from hemp, you will toss in your grave when one of the great great grand uncle/father children say lets run the dozer today and they pour the green power in, that engine will be just fine short of a natural disaster that covers it in ash or mud. As will the whole machine but people will breathe the fumes and say name that strain or something hideous like that. A great job of explaining. Marty T does a fine job on how to the back woods way on english equipment. I give him credit, he really watches what and how and even though very poor, does a good job with maintenance... him and watch wes work are fairly good, not your level but do good with what they have

[@jondavidmcnabb]

Don’t you normally paint the case and make it look new? Also on a previous build you used a coating (maroon colored) on the inside of the block?

[@raincoast9010]

Should the bolt heads on the fly weights be on opposite sides? (heads in direction of travel)

[@UpstateOutlaw]

Do you plan on installing the engine as soon as you finish rebuilding it or will it have to wait until spring? Cheers from Syracuse, NY 👍🏻👍🏻

[@kevinoscarson2941]

Been watching this engine build, my god is this an overbuilt engine! Everything is built to last, to be repaired, and again to last. Sure is different now...

[@isbcornbinder]

I worked on and for Cummins. Cummins are built with the same or better care and attention to details. Differently, yes. but better!

[@kevinoscarson2941]

I also work on Cummins, the new cummins isx, isl, paccar varieties, nothing comes close to this engine. Anything new, from the late 80’s things became thinner and cheaper.

[@kevinoscarson2941]

Oh and before I forget the new cat engines are poor, much rather have the cummins(however the DD15 is the engine to beat now).

[@skylinefever]

Well, if there wasn't a need to build engines for less smog, less weight, and less space, and more power, it might still be possible to build these kinds of engines. That is how I would explain things when someone who rebuilt cast iron gasoline V8s and saw that it was much cheaper to do than rebuild a Volkswagen VR6.

[@Dagrond]

Paint?

[@michaelbaumgardner2530]

You reckon that gasket is a shim from the machining process.

[@CaptainSir56]

Forgive me if this is a dumb question. Why no assembly lube or engine oil on the teeth of the gears? On the initial start up, wont they run dry for a bit until oil circulates completely through?

[@skylinefever]

I'm not sure. Many manuals do call for applying assembly lube to new timing gears or chains.

I guess i spoke too soon you did use some lube.
