KIT-JACKET WATER HEATER 1283811 - Caterpillar

Preliminary Test
Testing and Adjusting, "Swashplate - Calibrate"
Testing and Adjusting, "Main Control Valve - Calibrate"Machine Preparation
Illustration 2 g02280104
Position the machine on level ground in the service position. Refer to Illustration 2.
Raise the bucket 5 cm (2 inch) above the ground. Calibration Procedure
Perform the cracking point calibration and slope calibration for each PHMV.
Personal injury or death can result from sudden machine movement.Sudden movement of the machine can cause injury to persons on or near the machine.To prevent injury or death, make sure that the area around the machine is clear of personnel and obstructions before operating the machine.
Note: Machine movement is possible during swing valve calibration procedures. The calibration may be aborted by releasing all control levers.Cracking Point Calibration
Use the following procedure to detect the current of the valve cracking point.Monitor Procedure
Table 1
ACS Other Valves
Swing Valve
Start the engine.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F).
Enter the Service Menu.
Enter service password "9992".
Select "Calibration" menu.
Select "ACS Other Valves" from the "Calibrations" menu.
Select "Swing Valve Calibration".
Follow the instructions on the monitor to complete the calibration.
If the calibration was successful and no errors occurred, the display will indicate the calibration is complete. Note: The "Error" screen will be displayed on the monitor if an error occurs. The process of the calibration will not be saved and the process must be restarted.ET Procedure

ACS Valve Calibrations
Swing Valve Calibrations
Start the engine.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F).
Select the ECM for "Machine Control".
Select "Calibrations" from the "Service" menu.
Select "Swing Valve Calibration".
Select "Start".
Follow the instructions on the screen to complete the calibration.
If no error occurs, the calibration was completed successfully. Slope Calibration
ET Procedure
Enter slope (gain) code manually for the swing PHMVs. Slope calibrations must be completed using Cat® ET.

(24) Part Number
Locate the slope (gain) code of the PHMV. Note: The stamped slope (gain) code (21) can be found on the end of all PHMV's.Note: Refer to Special Instruction, REHS8064 in order to find the correct "ET Entry" for PHMV's with a Year / Week (22) stamp before 1338 (38th week of 2013).
Illustration 4 g03588361
Navigate to the "Configuration" screen within Cat® ET. Refer to Illustration 4.
Illustration 5 g03588368
Double click on a PHMV to change the slope (gain) value. The "Change Parameter Value" window will open. Refer to Illustration 5.
Illustration 6 g03588372
Enter the slope (gain) value "code" that is stamped on the solenoid nut into the "New Value" field inside the "Change Parameter Value" window. Click "OK" to update the slope (gain) value. Refer to Illustration 6.
Illustration 7 g03588376
Cat® ET will then populate the corresponding gain field with the correct slope (gain) value for the data that was entered in Step 4. Proceed to program the slope (gain) values for each PHMV.
Check to make sure that the new slope value is correct. Refer to Special Instruction, REHS8064 for Slope Value Reference Table.
