Manifold for Implement Hydraulics (1) Pressure tap for the fixed displacement piston pump.
Connect the steering frame lock.

Left Side Implement Main Control Valve (2) Line relief valve (lower). (3) Adjustment screw. (4) Locknut.Note: The following procedure will reduce the line relief setting by approximately 11800 kPa (1700 psi). This will lower the line relief setting to a test pressure setting that is below the setting of the main relief valve. It is necessary to perform this procedure in order to test the line relief setting.
Loosen locknut (4) .
Turn adjustment screw (3) counterclockwise by only two turns. Tighten the locknut.
Attach a 5P-4816 Gauge (50000 kPa (7500 psi)) to pressure tap (1) on the manifold.
Engage the parking brake.
Shift the transmission to NEUTRAL position.
Start the engine. Warm the hydraulic oil to normal operating temperature of approximately 49 to 65°C (120 to 150°F).

Front Dash (6) Diagnostic message screen.
Press the "OK" key on the keypad (5) repeatedly. The hour meter will appear on diagnostic message screen (6) .
On the keypad, enter "SERV" (the numbers 7378) and then press the "OK" key. Press the ">" key until the diagnostic message screen displays the following message:
Table 1
"IMPL RLF - FIX PUMP"    
Press the "OK" key. The following message will be displayed on the diagnostic message screen:
Table 2
"IMPL RLF - FIX PUMP"
"PRESS OK TO START"    
Press the "OK" key. The following messages will be displayed on the diagnostic message screen:
Table 3
"RLF PRES CHECK MODE IS TURNED ON"    
"LEFT VALVE ONLY WILL BE COMMANDED"    
"PROCEED W/ STANDARD SERVICE CHECKS"    The following message will alternate with the previous message in five second intervals:
Table 4
"PRESS < OR > TO SEE SPEC LIST"    Note: The displayed specifications on the diagnostic message screen are the expected results for the test. The specifications in the service manual may not agree with the specifications on the diagnostic message screen. The service personnel should use the specifications that are displayed on the diagnostic message screen for testing. These specifications could be changed by future updates in the software for the implement ECM.Note: The following specifications are listed on the diagnostic message screen:
The setting for the main relief valve on the fixed displacement pump
The pressure setting for the dump line relief valve
The lift time for the bucket with the fixed displacement pump
The torque converter stall speed
The double stall speed for the fixed displacement pump
The pressure setting for the left rack back line relief valve
The pressure setting for the left lower line relief valve
The pressure setting for the left raise line relief valve
Run the engine at low idle.
Place the bucket in the full TILT BACK position.
Move the lift control lever to the LOWER position in order to lower the bucket to the end of cylinder travel. Hold the lift control lever in the LOWER position. Record the gauge reading.
Decrease engine speed to low idle and lower the bucket to the ground.
Shut off the engine.The pressure reading that was obtained in Step 14 is the
