High Pressure

[763G]

can someone help me with this. I have a 763G Bobcat Some info on what i have done. Replaced drive motor, Drive motor carrier housing, shaft inter, outer bearings snap ring ,shaft seal, drain line filters. Still have high pressure on the right side causing shaft seal to go bad losing oil into chain case. Any info would be a great help. Thanks 763G

The main cause of high case drain pressure to push past the seal to the chain case is the case drain line filters, they plug up and build up pressure and push past the seal.
Could it be that simple?
Bad bearings can make teh shaft move and not seal right as well.

Hey Tazza I have replaced drain line filters. The drive motor carrier housing and shaft was took to bobcat they checked it. And made sure carrier shaft moved freely and end play not to exceed 0.007 inch. Is there anything else that could be the issue? Thanks for the help 763G
