Chicago Rawhide (*http://www.chicago-rawhide.com/) sells a fix for such
things called a Speedi-Sleeve. It is a very thin tube that doesn't
increase the OD of the sealing surface very much. They aren't hard to
put on (comes with a installation drift) and renew the sealing surface.

to get the crank turned down by *i think* 7 thou.

it did leak a bit past the seal when first fitted, but is now pretty good.

 OK, the Ambo is completely disassembled and I'm starting back up with
the engine. Question for the group: The crank looks pretty good, there
is some wear on the journals. I'll mic them Monday at work to get a
better idea if I have to go undersize. I remember a thread about
preventing the rear seal leakage. I can see where the seal has worn into
the crank. If I have the crank journals turned, should I get the aft
sealing surface turned to remove the wear groove. Will that make the
seal better, or will the reduced diameter make it more leakage prone?
Any other ideas to make sure this aft seal doesn't leak into my new
clutch disks?
