my super major doesn't have the hydraulic power it should at the bucket or the hoe, so I rebuilt the pump, Still doesn't have the lift so I put a pressure gage in front of the passthrough bucket valve and it was only registering 600psi. This leads me to believe that its a relief valve issue since the pressure line goes through the passthrough bucket valve on its way to the spool valve for the hoe. There are 3 acorn cap nuts on the passthrough valve. One on the main pressure line coming in, and one on both of the bucket valves. Is the pressure relief valve under the first acorn nut? or how do I find it. Next where do Get a new one? Thanks in advance. Shaun
