The operator is claiming the bucket lifting power is lacking, all functions good and fast. Does anyone have a pressure test procedure for the main hydraulic pressure along with specs and location of the main pressure relief valve. S/N 930KVRHN02891 Thanks
#7 is the test port for operating system pressures pressure spec is 3626 psi +/- 73 psi
I have posted the load sensing relief valve test spec What do you mean lacking in power ?will the machine not lift a given load or does the lift speed drop off? these machines are a lot more complicated than a standard machine. Due to the fact that the ECM plays a big part in controlling the implement system regardless of what the operator wants. The ECM is continually looking at system pressures verses engine torque loads and will derate the implement or hydrostatic accordingly so for example if you have a low power problem you will not be able to lift as much and or the lift speed will slow down while maintain engine speed
