Rear Left Wheel Motor Test Procedure (continued)
Hydraulic System: Testing the Hydraulic System
10. Chock the rear left wheel being tested to prevent from rotation.
Use extreme caution when performing this test. The wheel motor
being tested will be trying to move the machine forward.
11. Start the engine and run it at low idle speed. Check for the hydraulic fluid
leaks from the test connections and correct before the continuing the test.
12. Set the engine speed to approximately 3,210 rpm. Use a phototac to check
that the engine speed is correct.
13. While sitting in the operator seat, and with the brakes firmly applied to prevent
the rear wheels from rotating, slowly press the traction pedal in the forward
direction until the tester pressure displays 69 to 103 bar (1,000 to 1,500 psi).
14. Return the traction pedal to the NEUTRAL position. Release the brakes, shut
off the engine, and record the test results.
Note: Testing the wheel motor leakage in 3 different wheel positions will
give the most accurate test results.
15. Rotate the wheel motor being tested to 90º and retest. Record the test results.
16. Rotate the wheel motor being tested to 180º and retest. Record the test
results.
17. The flow meter reading should be less than 2.8 LPM (0.74 GPM) for the
tested wheel motor. If the specification is not met, repair or replace the
wheel motor.
18. Release the hydraulic pressure from the hydraulic system; refer to
Pressure from the Hydraulic System (page
19. Disconnect the tester from the pump outlet fitting and hydraulic hose and
connect the pump outlet to the hydraulic hoses.
