EK> Dave, I have been very successful repairing LMO for this problem.  I
typically will take the small collar off of the LMO drive shaft and remove the
6, interlocking plates.  I the take a small torch and try to remove as much of
the petroleum base lube that may be on these plates.  After that I recoat the
plates with black moly-lube and reinstall the plates.  Moly-lube is synthetic
and does not degrade like petroleum does.

Hope this helps.
