    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.

    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.

The giant steam engines assembled when horse power was all that was likely available to move the giant pieces.

    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
      @mikehunt3222 Місяць тому +2

      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. 😂

  • @jazzerbyte
    @jazzerbyte Місяць тому +41

    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.

  • @HANKTHEDANKEST
    @HANKTHEDANKEST Місяць тому +66

    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. 🐇🐇🐇

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.

  • @cadewey6181
    @cadewey6181 Місяць тому +25

    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.

    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.

    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.

    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!

      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.

    A friend of mine, when he knows he is replacing parts that have cotter pins in them, he does not even bother with pulling the pins. He makes sure they allow his socket onto the nut and he spins them off with an impact or breaker bar. He doesn't care what kind of damage the pin may cause because, the part is being replaced. If he is not replacing the parts, then he will be careful and he uses a new pin every time. I tend to remove pins just to keep a running inventory of what came apart and what needs to go back together.

    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.

    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.

      Old joke. Footbsll game, big animals vs small animals. The small animals are getting blown out. Suddenly, in the 4th quarter, the centipede starts to run wild, playing offense and defense, making tackles, blocking passes, making huge runs. The small animals gather round, and the rabbit asks "Where were you the first three quarters of the game?" The centipede shrugs. "Tying my shoes."

    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...

    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
      @jimrankin2583 Місяць тому

      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.
