Tests
The function of pump control valves is to send a regulated
pilot oil control signal to its respective pump regulator to
change pump flow in response to the actuation of control
valve spools. (See Pump Control Valve Operation in
Group 9025-05.) The purpose of test is to check that the
regulated pilot oil control signal increases as a function is
actuated and decreases when function is returned to
neutral by monitoring the front and rear pump control
pressure sensor readings. The valves are adjusted at the
factory and there should never be any need for an
adjustment in the field.
