Some background.
I bought a ford 1100 tractor with a FEL. It is old, but reasonable condition. When I bought it I was informed that it had a hydraulic leak around the area of the control valve. It is an older control valve, made by dukes fluid power. There is very little documentation available, but a basic schematic is here
Dukes fluid power
The tractor was also hard starting. I pulled the valve, stripped it down completely, put new o-rings etc in, put everything together. Leak was fixed, the tractor started a lot easier too. I had two problems though.
The hydraulics had lost a lot of power, they seemed to activate the relieve valve very easily. On the upstroke of the FEL, If I pushed the lever too far, it actually reversed the stroke.
I logically figured that I had a spool out of alignment somehow, pulled it apart, put it together carefully, and the problem is worse. Doing anything on the upstroke seems to engage the relief valve now, which is pretty noisy.
Any pointers, suggestions, help ???. I need to do some landscaping before next weekend.
Thanks
Bruce.
