Now I know why 904 was having issues

Thanks fellas.

Now I'm fighting getting the piston into the front clutch. Tried the freezer thing twice with no joy. Tried the homebrew lip wizard with no luck either. Really seems to be hanging up on the inner seal in the drum. When I take the inner seal out, its pretty easy to put the piston in working around the outer seal with the wizard thing. Put the inner seal back and it's like a hard stop. Just seems like that inner seal sticks out there too far. I've double checked it as the exact sames size as came out and made sure it was seated in its groove properly.

Inner seal should have the lip facing into the drum right?

Frustrated right now. :banghead:

Yea it's a pain in the backside sometimes, and yes the seal goes in there the way it doesn't want to go. :D

Something small, thin, smooth and flat, put down pressure on the piston with one hand and run around both inner and outer seals alternating between the two with your lip tool.

I'm trying to think of a common household thing to use for the tool, but I'm drawing a blank besides a tapered and polished feeler gauge.
