901 transmission main seal and rear main seal Options

[John90290]

I pulled the engine to complete the hell hole repair so figured I'd put in a new clutch. Glad I did, clutch disc soaked in oil or transmission fluid, take your pick. Also found the exhaust manifolds nuts hand tight on a couple of the studs and the thermostat cable off of the roller so that basically did not work.

Anyway.... I purchased the new seals - rear main and transmission shaft output but can't find any images or instructions on how to replace them? Usually this is straight forward but there seams to be some sort of recess in the RMS of the engine? Any diagrams or instructions would be appreciated.

Also, the clutch had a lot of material left on it, almost as thick as the replacement disc so I think the clutch was recent but they never bothered to replace seals so it's shot. The flywheel looks smooth and unmarred. Do I still need to resurface?

Thanks!

If flywheel is smooth, you are good. Did you get new bolts, pilot bearing, felt, flat plate and bolts for the flywheel re mount?

Seal should just pull out like usual rear mains. Trans seal needs removal of the guided tube and TOB parts, then be careful not to gouge the bore (very common) as this can lead to a leak. While your in there, make sure you have the plastic spacers that go between the TOB and the fork arms, and replaced the bushing in the fork.
