11.Verify pump flow at No Load as follows:
A. Slowly depress forward traction pedal to full for-
ward position.
B. Record tester pressure and flow readings. Unres-
tricted pump output should be approximately 35
GPM (133 LPM) at 1000 PSI (69 Bar).
12. Verify pump flow Under Load as follows:
A. Slowly depress forward traction pedal to full for-
ward position.
B. Apply an additional load of 1500 to 2000 PSI
(103 to 138 Bar) by slowly closing the flow meter.
The flow meter pressure gauge should read 2500 to
3000 PSI (172 to 207 Bar).
C. Record tester pressure and flow readings.
13.Release traction pedal to the neutral position, open
flow control valve on tester and shut off engine.
14.The Under Load test flow reading (step 12.) should
not drop more than 12% when compared to the No
Load test flow reading (step 11.). A difference of more
than 12% may indicate:
A. The piston (traction) pump swash plate is not be-
ing rotated fully (traction pedal & linkage is out of ad-
justment).
B. The forward traction relief valve is leaking or
faulty (see Traction Circuit − Relief Pressure Test in
this chapter).
C. The piston (traction) pump needs to be repaired
or replaced as necessary.
15.Make necessary adjustments or repairs and retest.
16.When testing is complete, disconnect tester from
pump fitting and machine hydraulic hose. Reconnect
hose to pump fitting and check for leaks. Lower machine
to ground.
