2. Read and adhere to the information provided in
(page 5–23).
3. Disconnect the attachment from the kit quick-disconnect fittings or remove
the covers and plugs from the quick-disconnect fittings.
4. Use 2 hydraulic test hoses to install the tester to the kit quick-disconnect
fittings. Make sure the tester is installed in the correct flow direction (from
the "P" connector to the "T" connector) and the tester flow control valve is
fully open; refer to
g355502
1. Rear remote hydraulic kit "P" connector
5. Start the engine and run it at low-idle speed. Correct any hydraulic fluid leaks
at the test connections before continuing the test.
6. Set the throttle to the full speed (3,400 to 3,500 RPM). Verify the engine
RPM at the drive hubs or rubber coupling with a non-contact tachometer
(phototach).
7. Make sure hydraulic fluid is at normal operating temperature by operating the
machine for approximately 10 minutes.
8. Sit in the operator's seat and engage the kit PTO switch.
9. Verify the pump flow at No Load as follows:
A. Unrestricted pump output should be approximately 21 LPM (5.5 GPM).
B. Record the tester pressure and flow readings at no load.
10. Verify the pump flow Under Load as follows:
A. Monitor the tester pressure gauge carefully while slowly closing the flow
control valve until 5,516 kPa (800 psi) is obtained on the tester pressure
gauge.
B. Record the tester pressure and flow readings under load.
C. Open the tester flow control valve fully.
11. Verify the kit relief valve operation as follows:
