hydraulics leak down

Dick E · May 13, 2009

I have a 430 Case with dual hydraulic valves for my loader. The bucket has starter leaking down. No fluid on the ground, must be leaking back to the sump. The boom holds just fine. Is there a seal that I need to replace, and where? Thanks Dick

I would eliminate the cylinders as the cause before I would suspect the valve. A failed piston packing on the dump cylinders will cause this. mEl

Ok I'll block one cylinder at a time and give that a test. Thanks

I disconnected each cylinder and capped the hydraulic lines one at a time. The bucket leaks down with either cylinder connected. So it looks like I tear into the valve.
