I have a Woods BH7500-1 on a Kubota L3600, the problem I am having is that the backhoe will not hold hydraulic pressure. If I raise the boom it quickly falls, if I put down my outriggers and raise the back of my tractor off the ground , the outriggers immediately lose pressure, I have removed the "system relief valve " but didn't see anything wrong with the copper washer or O-rings. The spring inside looks fine but unsure if it is holding the pressure or not. The manual says do not adjust preset at factory. I have removed the "port relief valves" and everything looks good as well. Hydraulics are full and no leaks anywhere. Any idea what the problem could be ??
