Release the parking brake.
Ensure that the parking brake indicator is ON.
Release the service brake.
Select the lowest maximum ground speed.
Increase the engine speed to HIGH IDLE.
Note the engine speed and record the engine speed onto the worksheets. Refer to Testing and Adjusting, "Worksheet - Troubleshoot".
Raise the blade off the ground.
Tilt the blade to the right. Hold the bulldozer control in the TILT RIGHT position.
Move the speed and direction control to the FORWARD position. The tracks should not move.Note: Do not stall both systems for more than 15 seconds.
Check the engine speed, the drive pressure of the front pump, the drive pressure of the rear pump and the implement pressure. Record the data onto the worksheets.
Subtract the second engine speed from the first engine speed in order to obtain the engine lug. The engine lug should be 125 40 rpm.
The drive pressure for the front pump at pressure tap "2" should be 44000 1000 kPa (6400 150 psi).
The drive pressure for the rear pump at pressure tap "1" should be 44000 1000 kPa (6400 150 psi).
The implement pressure at pressure tap "6" should be 20600 350 kPa (2990 50 psi).
