Also check the sealing surface (the crank snout) for wear grooves from
the seal. If these are present, try to get a fix-it sleeve (like 0.005
in.-thick sleeve, ID same as OD of crank, from a local
bearing/power-transmission place), or just leave the seal 1/16" or 1.5
mm _less_ than seated, if possible. This allows the seal's lips to ride
on a different part of the rotating member.
