North Central OH | Anyone know the charge pressure spec for a deeere 510c backhoe, having a low flow/slow hyd problem. The standby pressure 2500psi which is correct, checking the test port next to it which I believe is to check charge pressure is only 75psi and goes to zero if you try to move the hydraulics. So far we have checked the filter, cleaned the suction screen, and changed the suction hose. I also tried clamping off the hose between the filter and transmission, what else is there to check? Main hydraulic pump was rebuilt 200hrs ago and it did this suddenly. | |
