My B8200 is getting hydraulic oil into the engine crankcase. After advice from a Kubota dealer I installed a new hydraulic pump. After a few hours of use the hydraulic oil is still getting into the crankcase. Any help would be appreciated

Jiggermutt ~

There is a small (very small) o-ring behind the pump where it mounts up to the block, between the pump and block. If that is breached you can have transfer of oil.
Additionally, albeit you spoke of a new pump, the new pump is only as good as the assembler. If the shaft seal on the new (or even your old) has failed for whatever reason, the hydraulic oil will push right past this seal , over your pump shaft into the crank.

Hope this helps ~

I replaced the seal in the New hydraulic pump I installed. The seal in the new pump was no good. I have just worked with tractor for six hours and everything seems to be good. Thanks for the help. ....
