51 cub hydrallic system

Tom Durrer · May 11, 2014

have slow fluid leak in my hydrallic system. I think
it is the O rings. The fluid leaks out over a few days time. If I add more fluid everything is fine.
Could it be anything else? How hard is it to
pull the hydrallic system and change all the O rings and rubber boots.

Is the fluid leaking out on the ground, or just disappearing?

If it is disappearing, check your engine oil level. The most common failure is the O-rings in the hydraulic pump, causing the hydraulic oil to end up in the crankcase.

I didn't think it was that hard when I took mine apart, but then again I grew up on a farm and had some wrenching experience.

If you aren't good at remembering where things go, take LOTS of pictures.

Work in a CLEAN area, with lots of CLEAN rags on hand.
