Replacing rear main seal, What parts along the way can't be reused? Options

[rjames]

I replaced the clutch and flywheel last year and the rear main seal, but it looks like it's leaking again.
As part of the task of removing the pressure plate, clutch and flywheel to get to the seal, what parts can't I use again?

Do I need a new felt washer?
What else?

Think twice about re-using anything with "gasket" in its name. In particular, if you run gaskets on the CV joints (hey, some don't!) you probably don't want to re-use them. Especially if you wind up having to poke a screwdriver into them to get the CVs off the transmission output flanges.

Transmission linkage cone set-screws (only used in side-shift linkage) are good to replace when you take them out. (I don't always follow this, but I probably should.) The locking nib tends to get mashed into the shape of the thread and not lock as well over a couple of install and remove cycles.

Since you're going to have the linkage apart to pull the trans, consider replacing some or all of the bushings.

If the side shift console is leaking, this would be an opportunity to replace the seal inside of it.

You can clean up your transmission ground points and ground strap, while you're in there.

.... Eventually, you'll wind up with a completely rebuilt car if you keep doing things "while you're in there".... In our world, that is known as DWD, or Dirk Wright's Disease.
