Pressure tap for the proportional reducing valve (power shift pressure)
Connect a 3445 kPa (500 psi) pressure sensor to the pressure tap for power shift pressure.
Start the engine.
Place the machine controls at the following settings: engine speed dial "10" and AEC switch OFF. Refer to Testing and Adjusting, "Engine Performance - Test (Engine Speed)" for engine rpm settings.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F). Calibration Procedure
Enter the service mode. Input the password "9992".
