Piston Pump Cutoff Pressure (Hydraulic Fan) - Test and Adjust
The drive shaft rotates between the torque converter and the transmission whenever the engine is running. Contact with the rotating shaft can result in personal injury or death. The rotating shaft is located under the implement and steering pumps. Do not allow personnel into the pump bay area behind the cab when the engine is running. |

Sudden movement or accidental starting of the machine can cause personal injury or death to persons on or near the machine. To prevent personal injury or death, perform the following: Park the machine on a smooth, level surface. Lower the work tool to the ground and engage the parking brake. Stop the engine and remove the key. Block the wheels and install the steering frame lock. |
The fan drive pump is a variable displacement piston pump. There is no pressure relief valve in the fan drive system. The pressure and flow compensator valve on the pump controls the pump cutoff pressure. The pressure and flow compensator valve also controls the flow of hydraulic oil to the fan drive motor.
The Caterpillar Electronic Technician (ET) software must be used in order to override fan speed solenoid (5). Caterpillar ET will then provide the correct control pressure to the pump control. The fan speed solenoid is controlled by the engine ECM.
Note: Green hill act 2 paradise. Caterpillar ET is a software program that can be used on an IBM compatible personal computer.

The fan drive pump is located in the front of the pump compartment. The pump compartment is on the front frame under the operator compartment. The fan drive pump is in line with the hydraulic and steering pump.

- Engage the parking brake.
- Attach an unvalved nipple to a
0 to 16000 kPa (0 to 2321 psi) pressure gauge. Attach a section of hydraulic line to the unvalved nipple. Attach the hydraulic line to pressure tap (1). - Shift the transmission to neutral.
- Start the engine. Run the engine at high idle.
- Move the wheel lean cylinder to the end of the stroke. Stall the cylinder. At the same time, circle the moldboard. This will warm the hydraulic oil to normal operating temperature of approximately
60° ± 5°C (140° ± 9°F) . - Connect Caterpillar ET to the data link connector. The data link connector is located on the front face of the shift console. Start Caterpillar ET.
- Select the 'File' menu. From the 'File' menu, select the engine 'Electronic Control Module (ECM)' for your machine. Select 'Diagnostics'. Select 'Diagnostic Tests'. Select 'Override Parameters'. Select 'Engine Fan Bypass'.
- Enter '0%' for the 'Engine Fan Bypass Override Parameter'. Press 'Enter' until all warning messages disappear. This will cause the fan to run at maximum speed when the engine is at high idle.
- With the engine at high idle, use the 1U-6602 Photo-Tachometer in order to measure the fan speed. The pressure reading of the pressure gauge should be used as reference only. Use the following table in order to determine the correct fan speed and reference pressure.
Table 2 Fan Speeds Model Fan Speed Reference Pressure 14H 1210 ± 25 RPM 8000 ± 500 kPa (1160 ± 73 psi) 14H High Ambient 1350 ± 25 RPM 10000 ± 500 kPa (1450 ± 73 psi) 16H 1350 ±25 RPM 10000 ± 500 kPa (1450 ± 73 psi) 16 High Ambient 1470 ±25 RPM 11840 ± 500 kPa (1717± 73 psi) - If the pump cutoff pressure of the fan drive pump is not correct, the cutoff valve must be adjusted.
- Stop the engine.
- Loosen locknut (7).
- Turn adjusting screw (6) clockwise in order to increase the pressure setting. Turn adjusting screw (6) counterclockwise in order to decrease the pressure setting.
- Tighten locknut (7).
- Start the engine.
- Repeat Step 7 through Step 15 until the proper fan speed is obtained.
- Use Caterpillar ET in order to reset the 'Engine Fan Bypass Override Parameter'.
- Exit the Caterpillar ET program and disconnect ET from the machine.
