My backhoe will no longer move. Worked great for several years, then got weaker and slower and finally stopped moving all together. I changed the pto driven hyd pump, hyd filter and fluid. Still won't move. I did not bleed anything because I'm not sure how to except crack a hose downstream of the pump somewhere. Gonna change the adjustable hyd pressure valve next, if I can find one. Looking for parts for a Liberty BHM-155 5ft backhoe (3 point hookup). Specifically, a hydraulic pressure adjustment valve
