When I got my tractor it was leaking a bit from the PTO shaft. I drained all fluids and went to work on the resto. Having finished the motor I filled the trans with 80w-90. A couple of days ago I took the PTO cover off to replace the seal and trans lub started leaking out of the bearing. I cannot see any seal in the shop manual or parts book that would prevent trans lube from getting into the PTO clutch area altho the book calls for different lube in both housings. Any thoughts on this. I am currently baffled and really don't want to tear the whole thing apart unless I need to.
