[AT] Cub - Update

Sun Jul 5 16:01:39 PDT 2020

Thanks Mark.  I probably sound like I'm being very careful and objective,
which is partly true, but there is an emotional component, and yes this one
is already mine except for the payment.  (Go back and check Dean Vinson's
posts about "the one that got away" - thanks Dean!)

Agreed 100%, seals probably are 70 years old.  I will have to be on the
lookout for clues going forward, but it seems altogether possible it's
never been rebuilt.  No real need to go look at it again; implying, I
suppose, that it was wiped down prior to my visit?  The current owner
simply doesn't seem like that kind of guy.  And it's a long ride.  Yes, I
would say there's a chance that the oil I see on the pan is pan gasket
rather than rear-main.   My luck never ever goes that way, and I'm mentally
prepared to be splitting it some day.  BTDT on my previous Cub.  It would
be nice to get a few seasons of use mowing with it and maybe defer that
kind of work for "retirement".... not that I have any real idea when I'm
retiring (I'm 58 right now).  PTO wear... someone else on the list directed
my attention to it, and sure enough it's loose, so that told me this is a
common trouble spot.  I won't know whether damage is pulley, or shaft, or a
little of both until I get into it.  But, if it IS a common trouble spot,
it is known where to expect to find the damage.  Just not by me.

Thanks for the comments, much appreciated!
