[@spyroXcynder1000]

I have a feeling those mysterious gear teeth are from a previous catastrophic failure that wasn't cleared out before being replaced, or were left to make a speedy recovery in the field then forgotten about, before being parked.

[@the_darkgameryt]

that seems plausible!

[@AltGrendel]

My thoughts as well.

[@ronpeacock9939]

exactly my thoughts too...

[@trickstothetrades1801]

Mine as well

[@gregwhite7957]

Exactly my thoughts.

[@rexmyers991]

Hey Matt - I worked for a large Caterpillar company in Denver, CO in the early 70’s. (I am 81, now). I worked on a lot of D8 Cats. We changed out the pony motor as an assembly and never got the chance to tear one apart. Very interesting.

[@OleGramps53]

I believe the teeth were from a failed starter bendix that never was retrieved when they had the initial starter problem Matt. The size and number is similar to the teeth count on the bendix.

[@ronaldbeatty1887]

I don't know, those Pakistanies would throw that whole thing up on a lathe, hit it with a welder some paint and bada bing good to go.

[@erniesemmens8600]

Same thought

[@OldIronCanada]

Regarding the grey/silver sludge, I didn't see that anyone suggested it is actually LEAD from leaded gasoline. We used to call it grey paint. I was an apprentice car mechanic in the 60s when leaded gas was the norm. The grey paint would get so thick in the oil pan it would plug up the oil pickup. When removing an oil pan with that in it, it felt as heavy as if half a crankshaft was there. With the age of that pony engine, it likely ran most of its life with leaded gas.

[@mikehunt3222]

That’s what I was going to say, that it was lead from leaded gas. Torn down lots of old engines with my grandfather back in the day and every one of them had that sludge in it. Remember tearing down an old model T engine that had so much in it you could see where it was starting to touch the crankshaft. With that much sludge it probably only held about a quart of oil. We couldn’t get any oil to drain out before we took it apart. Most likely that’s why the guy said it would only run for about 10min before it would get hot and seize up and he’d have to let it cool down before it would start again. 😂

[@countrymuch2017]

Those teeth (my guess) are from a starter Bendix gear that was smashed from all that slop in the main bearings. Very interesting watching to dismantle something I'll probably never even see. Thank you Matt

[@BlueTheRage]

Yeah it look's like at about 19:30 you can see a bunch of teeth missing.

[@gaffer6846]

That is what I’m thinking too. It’s more than likely that is what caused the main bearing to fail to.

[@stevedibiase728]

Now even a Honda engine (everyone seems to swear by) couldn't take part of a fraction of this.

[@renevile]

a small gear like that, my guess is that it came from a broken starter that since have been replaced.

[@tywebbgolfenthusiast8950]

That makes a hell of a lot of sense. Can’t imagine anything being completely ground to paste without some fragments remaining, yet leaving the teeth mostly whole.

[@jackyoung42]

Those gear teeth look a lot like starter drive gear to me ⚙!

[@rundllexe]

This makes the most sense. If the crankshaft bearing was worn already, the starter was engaging only on the tips of the teeth, putting a lot more stress on it. Then it was swapped to fix it probably.

[@elev8torguy]

Sounds right. There would be a shaft without a gear somewhere in there otherwise.

[@SoupyOatmeal]

What I love about this channel is how you always steam clean or pressure wash an item before you start to video. That removes the blackened grease/oil sludge from the working surface and allows much better video content.

[@jazzerbyte]

Fascinating teardown! The crankshaft bearings on these ponies are commonly ruined by a leaky carburetor valve: if the fuel shutoff isn't used and a tank of gas drains into the oil, the oil becomes useless. Just a short runtime with ruined oil will trash the crankshaft bearings.

[@cadewey6181]

From an expert ‘ole cat skinner’ who has gone to the dozer home in the sky: after you start the Diesel engine, disengage the pony, but don’t kill it. Turn off the gas and let it run dry. That warms up the pony, drains the carb, and your pony cast iron warms evenly to fight dampness. I pulled down my D7-3t pony and found a shop that could weld up and grind the crankshaft back to spec. We had to bore the cylinders off center to get them round again. My 3T was dry clutch so the previous owner managed to beat on the bendix with the canvas-and-sheet metal links that break in the dry clutch. I found bendix parts from a 2U in a junk yard. Be thankful for your oil clutch and be assured it could be worse.

[@HANKTHEDANKEST]

Matt, at around the 10 minute mark you explain why you save old junk like this, but there's a neat side-effect of what you and those of use who care about old stuff do: there's a "gap" generation around old equipment where the old codgers who worked with it every day start to retire and pass on and the new kids in the field have new, high-tech fancy stuff and don't need things like pony motors &c., so off they go to collectors or the scrapper. With luck it's to a collector, and with greater luck still it's to a collector that will use it and instruct others in its use--like you're doing right now in this video. When these things pass out of every day use and into the "antique" world, there's a risk that they themselves as well as the understanding of their use is going to disappear forever. Think about steam engines, and how a whole generation of teachers were mostly lost before the nerds picked it back up again. All it takes is a generation of folks going "I don't know WTF that does" to lose that real-world, practical knowledge of the thing. Great example is live steam, which in the UK is SO MUCH more robust than here in North America. Why? The Brits took forever to switch from coal, we didn't. And that switch just so happened to coincide with folks starting to wake up and realize that it's worth saving the old stuff, even if it's not "useful" in a conventional sense anymore. Like a CAT pony motor. :) Thanks for giving a hoot about the old iron, Matt--preservation and conservation is a gift to future generations. There's always "a million of them" out there... until there isn't. Good, old machines deserve to be saved and ought to be put to work. They might be the only things that actually last in our age of emissions equipment and computer-controlled common-rail injection. Cheers, and I hope you and your pod have a happy Easter weekend. 🐇🐇🐇

[@Valtra103]

I am 29 and i keep two stroke pony motor on my 60s Belarus (mtz-50) tractor. Learned to rebuild them and all. One day folks like me might be only ones knowing how to run them. Bolt on starters exist, but I will run pony just for sake of keeping old iron alive, even now when I installed turbocharger on the main engine, and water to air intercooler. Learning, modifying and still keeping old stuff on the tractor is really fun for me.

[@mikeczerwinski3042]

After rebuilding starters and alternators for the last 40 years that appears to be the remnants of an opinion that came apart from a previously installed starter

[@disarm2k10]

Seeing the slack crankshaft, starter pinion's damage is a real possibility

[@rimfire2642]

[@TgWags69]

Wouldn't be hard to braze up that gear case. Worth saving. Doesn't have to be difficult. Prep the weld seem. It doesn't have to be huge. A 3/16 v is enough. Drill holes at each end of the crack. Build a nice big wood fire and get it all hot in some coals. Keep it in the coals while you heat up the joint and braze it up. Finnish by building up the fire a bit to bring it all up to an even heat. Cover it all with the coals and ashes when it dies down so it cools slow. Leave it till the next day. It sounds like a lot, but really isn't. Most of the effort is building a bonfire and watching it burn.

My take away from watching this is pure amazement with the engineers who designed and manufactured that whole assembly pre computers. I can't imagine the cost to make all the tooling to cast all those different pieces in an economical way. Mind blowing to me.

[@joshualester2735]

Thats my takeaway. You'd love the Henry Ford Museum. The sheer scale of these giant complex machines is mind boggling that it was done before computers. The highland park electric generator built in early 1900's is just awe inspiring if you think of the engineering challenges they faced and overcame. The giant steam engines assembled when horse power was all that was likely available to move the giant pieces.

[@AndrewBrowner]

i have to think due to the design the gear portion was doing some work it wasnt designed to holding up the flywheel/crank, so really the flywheel would of been much more centered when assembled but putting alot of wonky forces on that clutch pack and the bearings in the gearcase

[@soupofpossibilities8537]

I had a cat12 grader with a 2 cyl boxer pony. Pony threw a rod, broke some pieces out of the bottom of one of the cylinders, so I left the bottom oil ring off on reassembly. CAT dealer didn't want to mess with it which they told me by offering a ridiculous amount of $$$ to even look at it. Also got into a contention between CAT and auto shop as to who broke the end housing getting it off the crank, but CAT made it good with another from their boneyard. New pistons, rings, rods and bearings and it ran like new. Thank goodness for their boneyard, I also needed a steering knuckle for that machine. Apparently it's common for the spindle to fatigue crack, because mine cracked through, and the first one they got me was also cracked in the same place. The first spindle failed a bright early new year's morning, then broke the spindle on my case 580B trying to get the CAT12 off the runway, all before noon. Which goes to show you don't do ANYTHING before eating your black-eyed peas New Year's morning!

I agree with the mystery teeth coming from a previous starter catastrophic failure. I have never been in a position where my (and possibly my family's) next meal depended on me getting a piece of equipment operating so I could finish a job and get paid. The pressures of life and the mindset of someone who doesn't perform recommended oil changes and would also leave gear teeth inside a gear case is something I cannot relate to in any way. Matt has clearly established that neither the motor or the gear case received recommended maintenance and that the carnage occurred because of the wear on the engine main bearings which was due to oil that was filled with abrasive particles. Maintenance is not done for various reasons. I know/have known people that can always find money for beer and smokes but can never find money for oil changes. If every machine owner put maintenance high on the list of important things Matt wouldn't have a channel. Without so many mistreated machines we wouldn't have such entertaining videos illustrating the effects of that mistreatment.

[@patrickcolahan7499]

The gear teeth look like they may have come from an old starter Bendix that might have dynamited at some time. Most likely from the flywheel being as it is. Amazing that this engine still cranked over. Love the old iron, they are almost indestructible. No engineered obsolescence.

[@usernamesreprise4068]

That gear case is repairable actually, if it is made of cast steel it will be easier to weld than if it is made of cast iron, but even cast iron is weldable if it is heavily pre heated to a couple of hundred degree's first and then covered and allowed to cool very slowly after welding. Years and years ago when I first started in the trade it was an accepted part of the job and we refurbished many a block / gearbox casing/ and rear axle this way, that block is also repairable in the same manner, weld up the webs on the crank and have them turned back to spec by a crank grinder and do the same for any out of spec rotating surfaces and the rebuilt engine will be as good as new........important since as you said they are getting rarer than hens teeth now........there will come a day there wont be anymore left at all and you will be glad you didnt bin it. once they are gone there isnt any way back.

[@rudavega1]

Compare the shrapnel gear to a starter Bendix gear. At some point in its life it may have had an Old exploded starter from the crank bouncing around, The starter being replaced and you running it long enough to free the parts up from the sludge.

[@JenFitzgerald-t8e]

Hey Matt. I’m quite sure if you match those pieces up to some of the existing intact gears you will find the origin. My guess would be the starter drive. What I’m trying to say is that the pieces have been laying in there from some previous failure that you wouldn’t have any way of knowing about. There’s no telling how many starters have been on that pup over the years.

That’s what Sam said as well. But there was a Woodruff key laying with them and starters don’t have that.

The engineering that went into that motor alone must have been huge. Glad Matt took it apart for us mortals to see.

[@jimrankin2583]

Actually pretty simple. It’s 1/2 of a preexisting 4 cylinder design. The first series (most of them) were odd fire as you can imagine results when you have only the back half of the 4 cylinder. Then CAT designed a new counterweighted crank and a new camshaft that made it an even fire engine but then reverted back to the old odd fire design before they stopped making them altogether. That brings up the magneto ignition. Obviously there’s a difference between even fire and odd fire msgs, so when you’re looking for a msg to swap on something make sure you account for that difference. Same for mag distributer caps etc.

[@stevecurtiss46]

Matt, If you choose to weld that cast iron here's a tip. My Dad a fleet diesel mechanic who would be 102 ys now, would take an acetylene cast rod, strip a elecrtical 14 ga wire, wrap it in 1/4 inch wraps, drill both ends of crack, rose bud the cast then dip flux and weld one inch strips from each end till welded. This allows hot welded cast to be softer and more flexible. This is especially good for manifolds. Don't forget to bolt down a manifold so it doesn't warp. Hope this long winded story helps you some where along the way.

[@larryskeeper1197]

That babbitt bearing was probably a poured lead job which would explain why the metal in the bottom of the pan is so fine.

[@jimrankin2583]

Actually that one looks like aluminum. Babbett wouldn’t have cracked off like that when he tried to drive it out of the block. Just a note, there’s spacers on that oil pan which is actually the lower crankcase and bearing saddles. Without the spacers in the gasket line it’s possible to overtighten the bearing crush on that front bearing and lock the crank up. Maybe some of them don’t require them but some certainly did. CAT used aluminum for crankshaft bearings in the main engines too. Seems strange when we see mostly steel backed bearings with babbet overlay in old machines but they used them quite a while.

I hope you have at least some experience of "hand cranking" engines ! The use of the starting handle is probably the first introduction to the workings of the motor car, that those of us born in the fifties had ! I got my practice in, on my father's Rover 14, in the " here, you have a go !" basis. Later I found that 4 cylinder motor motors were easier. In my twenties I was still at it with decrepit small lorries on building sites,and dump trucks etc. If you are not used to hand starting motors you have missed out on learning how to wheeze and cough properly, such fun...

Try to take the crank to machine shop what they say. Try to turn it. The bearings you can pour yourself -> functional engine. The transmission - you can try to bronze weld it. It was quite often used technique in 50 and 60 when engine block cracked. Such a block was used for very long time afterwards. If you never made it this transmission is perfect thing for a try and learn.

When you hear the intro music you know you're in a good place!!

[@rustediron4062]

Mystery teeth could be off an old starter that's since been replaced. Just never got cleaned up...

[@UncleManuel]

You know the old engineer saying: "Everything was fine until it exploded." 😁😁🤘🤘

[@shubus]

While we missed the "new forklift" vid, we can agree this teardown was well worth the wait! Great work, Matt.

[@DieselCreek]

That video is coming lol

[@petecunnien5368]

Very cool little motor and the machining that goes into building those engines back then is just plain awesome!!

[@markc2107]

Great video as always love the sound track ❤👍🏻great watch on a Easter Sunday afternoon here in the uk 🇬🇧 keep them coming, Happy Easter Matt and everyone else 🙂👍🏻🇬🇧

[@cawsticky1322]

Electric start donkey (pony) engine,? oh the luxury ! I would miss the workout of the starting handle and the danger of having your teeth knocked out when it kicks back. Love these videos so much. thanks

[@davewarrender2056]

Hell yeah Matt, keep this stuff going , keep all that's salvageable , these analogue pieces are important, all this digital controlled crap is expensive and complicated to fix. Analogue can be fixed by anyone with tools , brains and experience

[@zburdette1223]

One thing I came across on an old firetruck I had to repair was the bendix housing was to thick. Because it was no the bendix teeth to fully engage the flywheel.

[@jeffhutchins7048]

I miss the Saturday videos, became a ritual for a while. BUT, YOU do what works for YOU! You're a busy man. I'm going to watch the videos no matter WHEN you post them!!!

[@bigbaby1177]

ME TOO!

[@ryanhodges7101]

You are absolutely right about those types of parts becoming more scarce. I worked at a Cat dealership and they had an entire used parts department that would search all over the country sometimes looking for a part. The pony motors are especially hard to find. Even good cores are rare.

[@Jodah175]

DC: sees silver paste "oh, its probably ok" Every Mechanic on the Planet: nope, nope she's pretty well screwed.

[@5of9]

🤣 True, yet the amount of "paste" indicates how much metal has worn away from various parts, not always just one part. 🤔

[@DieselCreek]

The first bit I saw wasn’t anything to write home about. The second batch of sludge was substantial lol

[@powellph]

I love taking mechanical equipment apart. I’m a little envious!

[@thisisus.504]

Good times. Lunchtime in the UK with Diesel Creek. Epic.

[@scrout]

I can just imagine the engineering meeting..." Hey Harry, we need a pony motor that's the heaviest thing known to man."

[@rickwalling1148]

It’s a amazing how cluttered the new massive shop is now! Soon it’ll be filled like his garage at the house! Time to build another shop Matt and get that one filled up. LOL LOL

[@DieselCreek]

There’s still room to drive a forklift around. It’s not cluttered at all.

[@Steve-ft3kb]

YDCMV...your definition of clutter may vary...AKA....not everyone uses forklifts as clutter guages😂

[@sloppystooly5439]

Im really surprised after the video with shop cleaning machine. Glad to see you getting that brand new building broke in well, greasy floors insulate well, lol. Cool video Matt!

[@DieselCreek]

I clean the floor pretty regularly

[@danhard8440]

morning all you DC boyz got your coffee?

[@NovaFragment]

Jusst got into bed so is perfect timing for a DC video

[@Mr.NiceGuy80]

Coffee, check!

[@joshhasselgren3889]

Check!

[@AJ_Gal]

Does a tall boy can of Monster Energy count?

[@davidcolesr.8628]

Yessir

[@motoXjake]

30 seconds in and i approve of this intro over the honking rigs... this is far better!

[@stansdds]

Old things are great, repair as long as possible and when no longer possible to repair, strip off every reusable part to keep other old things working.

[@freetolook3727]

I hear you on saving old parts. When I had my RV repair business, I saved old awning and appliance parts. Not everyone can afford new RVs and when old style awnings and appliances broke rather than having to buy a new awning or water heater, I kept them going with some new old parts! 😂

[@ClintsHobbiesDIY]

RIP Pony. Congratulations on 3/4 million subs Matt.

[@MrPaully69]

who else does this each time a new video comes out I sit here scanning his work shop for new toys and etc .🙂

[@AntonioClaudioMichael]

Love the New Intro Matt 0:02 Freaking Awesome @Diesel Creek

[@chubbysumo2230]

the flywheel is likely heavy so that you have some amount of rotating mass and stored energy so the pony motor doesn't just stall but instead has some store energy.

[@KB10GL]

Back from the mid '60's when I became an apprentice mechanic, through to the end of the '70's, I worked on everything from lawnmowers to Cat D9 Bulldozers. The main dozer in the fleet at the time was the D8E. These were the four cylinder models with petrol engine start. We called then Donkey motors. The one I loved more than the others was one tractor that had a right angle drive for a hand crank start of the Donkey engine. At one time the operator boasted that he could hand start his D8E, in the snow, Sure enough, he knew his business & hand cranked his Donkey motor to life & let it run while he slowly rolled a smoke & lit it. He then pulled it into low gear & engaged the flywheel, then went to make a cup of tea. Next, change into high gear & let the engine turn over while enjoying a 'cuppa'. & a smoke. After a time he mounted his steed, & started it up in the usual way, fulfilling his boast. None of the others in the fleet had this hand crank feature, but those D8's worked & worked & never ever really let us down. [Except the one that slid sideways off the trailer & bent the blade.] That was about fifty years ago. Greetings from Australia.

[@jimrankin2583]

D7 had the 4 cylinder D339 through the E models. 48Axxxxx serial numbers and there were nearly/identicsl US military tractors with their own serial series maybe 76Xxxxxx?? I agree with what you were saying. No other way a man could take a quart of gasoline and a starting rope in some cases or a hand crank and go start a cold diesel tractor in about any weather.

[@Madjock56]

Cheers for the content and ur merch is top notch ordered the t shirts 8 days ago from Scotland where i stay and they arrived today april 2 2024 great delivery time for a overseas delivery thank you again

[@REDBIRD-95]

Diesel Creek and breakfast, a perfect combination😁 Happy Easter Matt.

[@DieselCreek]

Same to you!

[@Innov8orRepair]

Failure analysis is probably my favorite part of fixing things and where I get the most learning done. I'm always asking: How did it happen? How can I fix it? Can I improve it to reduce or remove the failure point?

[@bubby650]

YAY! The intro music is back. Thanks Matt.

[@anned8634]

23.56 that looks like a hand cast babbit barring not a insert. i had to learn how to cast babbit baring in old mining equipment. It can be fun. sometimes in remote areas old repairman could not get barring inserts and would pour their own babbit barrings as replacements.

[@danielburgos9073]

Those gear tooth are from another starter they put on the pone motor diesel
