FILTER GP 3G7233 - Caterpillar

High Pressure Cutoff (Testing and Adjusting)
Connect a 25000 kPa (3600 psi) pressure gauge to the quick disconnect on pump discharge line (8) .
Disconnect the fan solenoid.
Run the engine at high idle.
The pressure at the pump discharge port should be 19388 350 kPa (2812 50 psi).
If the pressure at the pump discharge port is not 19388 350 kPa (2812 50 psi), then remove the cap from high-pressure spool (9) on the pump compensator. Continue to run the machine at high idle. Adjust the high-pressure spool until the gauge reads 19388 350 kPa (2812 50 psi). Replace the cap on the high-pressure spool.
Reconnect the fan solenoid when the adjustment is completed.Hydraulic Fan Speed (Testing and Adjusting)

Place the transmission in the NEUTRAL position. Engage the parking brake. Connect Caterpillar Electronic Technician (ET) to the diagnostic connector (11) .
Illustration 8 g01197347
Start ET. When ET initializes, select the engine ECM from the choices that are available. Refer to Illustration 8.
Illustration 9 g01197353
Check all Fault Codes under the engine ECM. Ensure that no faults are present in the fan drive system. Ensure that no faults are present with the hydraulic oil temperature sensor, the engine coolant temperature sensor, or the inlet manifold temperature sensor. If no faults are present, begin the calibration. Select "Service > Calibrations > Engine Cooling Fan Calibration". Refer to Illustration 9.

The screen that is shown in Illustration 10 will appear. Follow the instructions on the screen. Click on "OK".
Illustration 11 g01197350
The "Calibrations" screen will appear. Select both check boxes and click on "Begin".

Continue running the machine at high idle. Use the photo tach to measure the fan speed. Adjust the current for the fan solenoid by using the arrows at the bottom of the screen. Increasing the current will decrease the fan speed. Decreasing the current will increase the fan speed. Adjust the current until the fan speed is 1200 50 rpm.Note: The procedure on the screen may specify a different value for the fan speed. Do not use this value. Set the fan speed according to the above instructions.When the fan speed has
