Test Procedure (continued)
Hydraulic System: Testing the Hydraulic System
A. Monitor the tester pressure gauge carefully while slowly closing the flow
control valve
B. The system pressure should reach approximately 17,235 kPa (2,500 psi)
before the relief valve opens. Record the tester pressure reading.
C. Open the flow control valve fully, move the throttle to low speed, and set
the key switch to the O
12. If the relief pressure can not be met or is greater than specified, the kit relief
valve is damaged and should be repaired or replaced.
13. The under load test flow reading (step 10) should not drop more than 20%
(3.8 LPM (1 GPM)) when compared to the no load test flow reading (step 9).
A difference in flow of more than 20% (Under Load > No Load X 0.8) may
indicate:
A. A restriction in the pump inlet line.
B. The optional attachment pump is worn and should be repaired or
replaced; refer to
(Optional) Hydraulic Pump (page 5–112)

14. After testing:
A. Remove the hydraulic test hose(s) and tester.
B. Protect the kit quick-disconnect fittings from contamination by installing
with the covers and plugs provided with the kit.
C. Check and adjust the level of the hydraulic fluid in the hydraulic reservoir;
refer to the traction unit Operator's Manual.
D. Start the engine and check for any hydraulic fluid leaks. Repair hydraulic
leaks if necessary before returning the machine to service.
