that the hydraulic pump is at full stroke when traction pedal is pressed fully in
forward position.
4. Clean the fittings and the hydraulic tube shown; refer to
g299564
1. Hydraulic pump (P1)
5. Remove the hydraulic tube and use 2 hydraulic hoses to install the tester to
the exposed fittings. Make sure the tester is installed in the correct flow
direction (toward the wheel motors) and the tester flow control valve is fully
open.
6. Start the engine and run it at low-idle speed. Correct any hydraulic fluid leaks
at the test connections before continuing the test.
7. Start the engine and move the throttle to the full speed:
• Model 31900 and 31901 = 3235 rpm
• Model 31902 and 31903 = 3150 rpm
• Model 31907 and 31909 = 3235 rpm
8. Make sure hydraulic fluid is at normal operating temperature by operating the
machine for approximately 10 minutes.
9. Use the TDM display/controller screen to verify the engine speed.
10. Verify the pump flow at No Load as follows:
A. Slowly press the traction pedal to fully F
B. Unrestricted pump output should be approximately:
• Model 31900 and 31901 = 107 L/minute (28.3 gallons/minute)
• Model 31902 and 31903 = 104 L/minute (27.6 gallons/minute)
