10. Verify pump flow Under Load as follows:
A. Watch pressure gauge carefully while slowly closing the flow control valve
until 55.2 bar (800 PSI) is obtained on gauge.
B. Record tester pressure and flow readings under load.
11. Set throttle to low speed and shut off engine.
12. The under load test flow reading (step 10.B) should not drop more than 15%
when compared to the no load test flow reading (step 9). A difference in flow
of more than 15%, or the inability to achieve specified pressure may indicate:
A. A restriction in the pump intake line.
B. A worn and/or slipping drive belt.
C. The gear pump (P2) is worn and should be repaired or replaced.
13. Disconnect tester and reconnect hose to pump.
