Replacing main seal - what else while engine is out?

[restcon]

I'm replacing a leaking main seal on my 74 Thing. While I have the engine out what else should I replace? Clutch? Transmission seal?What parts are required?

There is a graphite o-ring that goes along with the main seal. Part # 311 105 295A. If the throwout bearing feels chunky or gritty replace it, otherwise they last a long time if you don't overuse the clutch.

Replace the o-ring any time you take the flywheel off the crank. It should go in dry, to a completely cleaned out grooved.

Before removing the pressure plate, mark its orientation so it goes back on in the same place for balance. Same with the flywheel; a hammer and centering punch works well to make dots on flywheels, pressure place, and crankshaft dowel pins.

If the transaxle input seal is dry, I don't usually replace it. Check the transmission/motor mounts for cracks, and the throwout arm for hairline fissures.

Good luck!
