Common Information
TASK 71-00-00-700-066-B00 Adjust Procedure For The Oil Pressure Pump Trim Valve, Testing-000
Adjust the Trim Valve
Obtain corrected oil pressure at idle. Refer to TASK 71-00-00-700-051-B00 (TESTING-000, CONFIG-002) for limits. Record the corrected oil pressure.
Identify the trim valve located on the oil pressure pump and filter assembly. Refer to Figure.
Deleted.
Temporarily identify relative position of trim valve to pump casting. Use marker.
Adjust the trim valve. Refer to Figure.
Hold the trim valve screw with a suitable wrench and loosen the self locking nut. Turn counterclockwise to loosen the self locking nut.
Turn clockwise the trim valve screw as necessary.
Record the rotation amount of the trim valve screw.
Hold the trim valve screw with a wrench and turn clockwise the self locking nut.
Torque the locking nut to between 290 to 370 lbf.in (33 to 42 Nm).
Measure and record the dimension L. Use a sliding caliper.
Do an idle check. Refer to TASK 71-00-00-700-003 (TESTING-003).
Check and record the measured oil pressure at idle.
Correct the oil pressure at idle.
If corrected DMOP is above the lower limit, clear the engine for further service.
If corrected DMOP is still below the lower limit, start procedure again.
If you do not get minimum DMOP, reject the pump.
