Starting on my D2 again

Randy,

How do you know your clutch is slipping? You pull the lever back to engage it and it should snap when it locks in (kinda like a 2 cylinder Deere but backwards). The clutch disc is a fiber disc with teeth on the outer edge that slip into matching teeth in the flywheel. It's common for those teeth to wear or break off the clutch disc so the flywheel no longer drives the clutch disc. When that happens you engage the clutch and the flywheel just rotates around it. You must split the tractor to replace the clutch.

If your engine is stuck I would recommend pulling the head off just to take a look inside. Rainwater has a bad habit of finding ways to get inside an engine. Water can do unspeakable things to Valves, Valve Seats, Pistons and Cylinder Walls.

Magneto parts should be available from Caterpillar or just about any magneto repair shop. You could also try NAPA for mag parts too.

Rich,

When I pull the clutch lever back i get a good "snap" It will bog the lead tractor (pulling me) down. I can then "steer" with a load on the tracks. I truely want to pull the head, but dont have the building to do it in at the moment, I put a penetrant down the exhaust in hopes of breaking the rings free and dislodging any rust in the cylinders. I did pull the valve cover and valvetrain apart and none of my valves are stuck. It was clean as a whistle under the valve cover. I do know the best thing to do is to pull it apart, but for the time being I dont know if I want to do that. I didn't know NAPA offered mag parts? Thanks for the advice! It is an American Bosch mag, I purchased a shop manual at the Jones show this last weekend, should help! Also I do have a blade on mine, was wondering if the hydraulic pump might be holding me back on rotation?? Is that hard to get apart?? I can get the crank to turn about 5 to 10 degrees each way (hard to tell from operators position)

Looking forward to this thing, should be a neat project.
Thanks for the help and posts, any advice or comments are welcome
Want to soak up all the info I can!
Thanks,

Randy

If the compression lever is in the "START" position, any water in the cylinders will blow out as there is no compression.

Thanks! drujinin

I am missing the lever and likage for decompression, but i can still move the arm at the back of the head.

My son used to complain of this when he continued to blow off his chores.....

Seems to me it could be called motivation! Naturally it was just a love tap. 😆

Old_n_slo,

hahaha, I never would have found or compared that! Thats hilarious👍

If you can get the crank to rotate you're probably going to be okay. The hydraulic pump could be holding things up but I wouldn't bet on it. You could have crap in one or more cylinders, a stuck lifter(s), stuck injector pump lifter, etc. etc. Keep the loose juice flowing into the cylinders and let it soak. Try rocking the engine back & forth. If you can pull the hydraulic pump off that would help, you could even make a tool to go through the radiator and engage the crank to help roll the engine over.

When I first looked at the D2 I bought last October it was stuck. As I was pulling on the fan blades I noticed the crank wiggling a bit. After rocking the fan back & forth the crank would move farther each time until it would roll completely around (bad idea on my part, that only drove the purchase price up :lol😊. Hopefully you'll get lucky too.

P.S. I don't have a building to work in either (my garage is WAAAAAY to full) but a good shade tree works too. Just keep everything clean and covered.

I always figured that if they could keep tractors running up on the Alaskan/Canadian highway by working under a tree or tarp, then I wouldn't complain too much about working outside.
Of course the Air Conditioning in summer and Heat in winter in the insulated shop are nice! 😆
