Steering Frame Lock in the LOCKED Position
Move steering frame lock to the LOCKED position.Test Procedure
Prepare the machine for testing by completing the procedure that is specified in the Service Manual module Testing and Adjusting, "Machine Preparation for Troubleshooting" for the machine that is being serviced.
Illustration 3 g06048241
Brake/Fan Valve is located in the Hydraulic Service Center on the right side of the machine.
(1) Fan solenoid
(2) Fan pump discharge pressure port
Disconnect the harness from the fan solenoid (1) located in back of the solenoid.
Connect a pressure gauge that can sustain pressures up to 34450 kPa (5000 psi) to the fan pump discharge pressure port (2). The port is located in the hydraulic service center as shown in Illustration 3.Note: The pressure will need to be released out of the system to attach the pressure gauge.
Start the engine. The engine should be at high idle throughout the warmup procedure. Continuously stall the TILT BACK position and simultaneously raise the lift arms at full speed. When the lift arms are almost raised, cycle the tilt cylinder to the FULL DUMP position. Then cycle to the TILT BACK position. Continuously stall the TILT BACK function and simultaneously lower the lift arms back to ground level. Without stalling the rack back function, cycle lift function to raise and lower the lift arms. This procedure will allow the pump to operate at low pressure and circulate oil throughout the system. Repeat this procedure until the hydraulic oil is at 62° 8°C (143.6° 14.4°F)
Increase the engine speed to high idle.
Observe the pressure reading. The cutoff pressure should be 22500 700 kPa (3260 100 psi). If the cutoff pressure is correct proceed to Step 7 in the next section. If the cutoff pressure is not correct, proceed to the following section for instructions to adjust the cutoff pressure.Adjustment Procedure
Turn off machine.

(3) Adjustment locknut for cutoff pressure.
Locate the fan pump on the right rear of the machine in the engine compartment. See Illustration 4.
Loosen locknut (3) and use an internal hex wrench to adjust the pressure. Turn the adjuster screw clockwise in order to increase the pressure setting. Turn the adjuster screw counterclockwise in order to decrease the pressure setting.
Tighten locknut (3).
Start the machine and measure the new pressure setting with the engine at high idle.
Repeat steps 3
