Low Hyd Press Only 600 Psi---Installed New Pump Already

Customer Question

Low Hyd Press Only 600 Psi---Installed New Pump Already
Submitted: 2 years ago.

You replaced the hydraulic pump with no improvement? Did you remove the relief valve in the valve body inlet side and check it? The relief valve has to hold pressure, and if it leaks, pressure will not increase. It is located on the inlet section of the hydraulic control valve, Remove it and examine it for blown o'rings or damage.
