[AT] Cub - Update

[Mark Johnson]

Steve:

I think we all recognize that oil seals on 70 year old equipment are 
questionable at the very best. It might be interesting to go look at it 
again in a few days and see if any of those leaks are 'progressing' in 
serious ways, provided you can do so without annoying the current owner. 
If the front main seal is good, that's a good sign. Is there any chance 
that some of the leakage toward the back of the engine could be oil pan 
rather than the rear main seal? My experience with engines of all types 
has been that oil pans (and oil pressure sending units) are more 
problematic than main seals...although my school bus driver had a rear 
main seal fail...he got the seal fixed right away, but a couple of weeks 
later, we were about 2 miles out of town on the highway when the 
crankshaft broke with a mighty rumble. Fortunately, there were 3 buses 
that ran together for the first few miles out of town, so Joe didn't 
have to get hold of the school or parents - would have been tough in 
1972 with no 2-way radio in the buses and no cell phones. We crammed 
into the other 2 buses and everybody got home.

Compression, clutch, and brakes all seem to be on the positive side. Is 
the PTO wear on the tractor's shaft splines, or is it on the attached 
pulley on the mower? Lots less work if it's on the pulley!

If anyone can provide this Cub with a good home, I'd say it would be 
you, or someone like you!
