Fan pump (located on the right side of the engine)
(3) Steering pump
(4) High-pressure cutoff spool
(5) Margin spoolMargin Pressure (Adjusting)
Loosen the locknut on the margin spool (5).
Adjust margin spool until the differential is with the proper range.
Tighten the locknut on the margin spool.High Pressure Cutoff (Adjusting)
Ensure that the machine is at high idle and the fan solenoid is disconnected.
Loosen the locknut on high-pressure cutoff spool (4).
Adjust the high-pressure cutoff spool until the gauge reads within the proper range.
Tighten the locknut on the high-pressure cutoff spool.
Reconnect the fan solenoid after the adjustment is completed.Hydraulic Fan Speed (Adjusting)

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, engine coolant temperature sensor and inlet manifold temperature sensor. If no faults are present, begin the calibration. Select "Service > Calibrations > Engine Cooling Fan Calibration". Refer to Illustration 12 and Illustration 13.

Ensure that the parking brake is set. Run the engine at high idle. Click on "Next" in the lower left corner of the screen.
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 within the proper range.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 been set properly, click the "Next" button in the lower left corner of the screen.
