Ok, I thought I had it working fine but it seems that the Bacot back boom doesn稚 have enough pressure to be effective. I have removed the relief valve for that particular control and cleaned it and then it works for a while but seems to revert back to not having enough pressure while in the field. Does anyone have any experience in adjusting or cleaning the manifold or relief valves? Is it possible that I have a relief valve sticking or dirt in the Backhoe hydraulic manifold that could be causing this issue? Any help is appreciate it. Also note the although the backhoe looks in perfect show room shape, the relief valves have seen better days and have some rust on them with even one of them having a set screw that cannot be adjusted. My fear is that I will have to replace this one valve which is listed at $500.
