Lynn,

Thanks for the confirmation.  I don't recall using any sealant on it during
re-assembly (I may have, I just don't recall for certain).  If it is in fact
leaking, I guess that means that I'll be pulling the gearbox, flywheel,
counterweight and bearing carrier.  Or, is it possible to remove the six
bolts and slide it out a 1/2" and, using a small brush, work some Permatex
into the gap, then re-assemble?  This would be without removing the "BIG
NUT".

Mark S.
