Jeff's 727 rebuild thread

Right on......I'll be putting that drum together tomorrow!

Jeff, pay particular attention to the piston seal lip when you fit the piston into it's bore. You cant get a lip wizard in there like you can with the forward clutch piston & great care has to be taken not to roll the seal lip over the chamfer in the drum. It has to slide down the chamfer & into it's bore. I find the chamfer is a little too shallow, but with a little patience the piston normally drops in fine without too much fuss. The secret is to use lots of assembly grease/Vaseline/ATF to lube the seal lip & the chamfer. Dont be shy with the lube. You'll see what I mean when you get round to fitting the piston.
Cheers. Gaz.
