Pfc Pump High Pressure Standby Check And Adjustment Procedure - New Holland T8010 Manual

PFC PUMP HIGH PRESSURE STANDBY CHECK
Perform this test when all remote circuits and hitch system do not operate with full power. This would be noticeable
when maximum power is needed such as when lifting heavy hitch loads, or maximum pressure is required by a
remote circuit.
Test Fitting Tool Requirements:
• 17 mm wrench and 3 mm Allen wrench.
Preparation
Remove the plug at rear of high pressure compensation spool and install the diagnostic fitting (1) from Kit
380040106 into the pump compensator.
IMPORTANT: Do not shift the transmission control lever out of park.
- Install a 5000 PSI (350 bar) pressure gauge with hose onto the diagnostic fitting at the compensator.
- Start and run the engine at 1500 RPM.
- Place the number one remote valve control lever into the extend position.

High Pressure Standby Specification: 3250 PSI (224 bar)
Remove the cap from the high pressure adjustment. Loosen the lock nut and use the Allen wrench to adjust the
pressure. Turn the adjustment screw in (clockwise) to increase the pressure, and turn the adjustment out
(counterclockwise) to decrease the pressure setting.
A. If the correct pressure could not be obtained the PFC pump may be damaged. Perform the PFC piston
pump flow.
