The weather has wormed and now is the time to return to restoring my CC-3. The tractor was stuck for past 25 years. I broke loose the engine yesterday (I beat the piston down with a 2x4 after soaking the cylinders with oil all winter).

I need to know how hard it is to split the tractor and remove the oil pan. I need to pull the pistons, inspect and clean and rings and hone the cylinders. My real concern is the disassembly and reassembly of the clutch when splitting the tractor. I have never split a tractor this big or OLD before. Any tricks? What do I watch for?

I have a floor jack, bottleneck jack, and engine stands. Can I split it with only these limited tools, or do I need overhead winches? Any help or pointers would be greatly appreciated. Thanks

You can do everything you are talking about working through the inspection holes in the oil pan. Not necessary to split or remove the oil pan. You can actually remove the piston rod asemblies through the inspection holes if you need to.

On my Case LA book it says to get two 12 inch long bolts that will fit in the two outer most bolt holes on the side of the bell housing. Install these and then put a jack solid type like a house jack or block with wood the back of the tractor just under the front of the tranny.
Next put your floor jack under the rear of the rear of the engine use a block of wood to support it good. Now remove all bolts on bell housing then pull front end forward to the end of the long bolts. You can now block the front end for safety and then remove the clutch and pan. Just make sure that its well blocked before getting underneath it. use large blocks of wood. We used 2X6s and crossed nailed them to build up the height this will make a strong block that won't tip or brake. (2x6 by 12 in. takes 4 to make one level) At more levels as needed.
Need any more help I can send some pics from my manual its not the same but will give you the idea of how its done.

Walt, thanks I understand perfectly. Your instructions have helped me think about the process in greater detail. I will use 2x6 blocks to build a stand 12 inches square to set the transmission on. The long bolts will make it much easer remove an replace the engine.

Thanks, I read some time ago that the clutch is some sort of an "oil clutch� that sits in an oil bath. It that true or am I confusing the CC-3 some other tractor like my LA (yet to be restored and also with a stuck engine)?

I'll give you a little bit of info but the others will give you more. To remove the oil pan you don't have to actually split the tractor. You can support the rearend by the back of the motor with blocks of wood and a jack under them. Remove all the oil pan bolts and slightly loosen the engine/rearend mount bolts. This will allow the tractor to "sag" in the middle and the oil pan to come down. Hard to explain without pics.

I do suggest however, to split the tractor to check out the clutch and pressure plate. My two cents.
