727 Rebuild Blues

Ok, All that really helps narrow it down. Now I understand how the front clutch is fed. So those two rings fit great in the bore. That's a good check. This time I just installed the front clutch on the pump & can now see what's going on. The clutch is working but seems to be really leaking at the inner piston seal. Guess I pickup a new one tomorrow & see if that cures it.

Is the vasaline type assembly ok to use on those piston seals? Or could that be why it's leaking past so bad?
