The bucket on my old Thomas Skid Steer started to leak down last year and has done nothing but get worse. The boom stays up fine but the bucket uncurls (dumps) constantly unless you keep hitting the pedal every few seconds. No sign of external leakage. To try & diagnose it I temporarily put a couple ball valves in the lines between the spool valve & cylinders. If i close them the bucket stays up fine. To me this means the leak is not internal in the cylinder but must be in the spool valve.
I think this spool valve has check valves in it. Looks like a couple big bolt heads above the spool anyways. Could it be as simple as one of those leaking or do I need to remove the whole valve assembly and tear it down? Was thinking about working on it tonight.
