ACCUMULATOR GP-PILOT OIL 2000750 - Caterpillar

line (8) from the filter base to fitting (5) for the oil inlet on the governor.
Connect line (6) from the fuel transfer pump to fitting (2) for the inlet fitting of the fuel transfer pump.
If the governor is equipped with a fuel ratio control, connect a regulated air supply (hand pump or squeeze pump) to the fuel ratio control. Turn on the regulated air supply in order to pressurize the fuel ratio control.Note: A regulated air supply of 140 to 210 kPa (20 to 30 psi) must be used to avoid damage to the fuel ratio control.
Install the pressure gauge that is supplied with the governor calibration bench on the quick disconnect fitting on the filter housing for the lubricating oil.Note: Ensure that the fuel shutoff solenoid is latched in the RUN position. To latch the fuel shutoff solenoid in the RUN position, refer to the Systems Operation, "Fuel Shutoff Solenoid" topic in this manual. If the fuel shutoff solenoid is a nonlatching solenoid, remove the fuel shutoff solenoid with a 9U-5120 Spanner Wrench and plug the opening.

Install lever (12) on throttle lever (11). Turn throttle lever (11) clockwise in order to move clevis pin (14) away from the governor housing. This movement will permit calibration pin (13) to be installed.
Remove the collar from calibration pin (13). Insert the calibration pin through the hole in oil collector cup (9) then into clevis pin (14) of the governor output shaft.
Slide the collar over the end of calibration pin (13) until the calibration pin contacts clevis pin (14) .

Connect one end of spring (15) to the hole in lever (12). Connect the other end of spring (15) to the hole in base (16) for the tachometer.
Connect the test bench to an electrical outlet.
Turn the switch for the pump to the ON position in order to start the lubricating oil pump. The pressure of the lubricating oil should stabilize at 205 to 275 kPa (30 to 40 psi).Note: When the oil pressure is stabilized and the throttle lever is held in the high idle position by spring (15), calibration pin (13) should be in contact with the governor housing.Note: When a governor that has been previously adjusted is being checked, calibration pin (13) must contact the governor housing. If calibration pin (13) does not contact the governor housing, the governor must be completely readjusted. Refer to the Testing and Adjusting, "Governor (Type) - Adjust" section in this manual.
