CAUTION
Do not close tester valve fully when perform-
ing this test. In this test, the hydraulic tester is
positioned before the manifold relief valve.
Pump damage can occur if the fluid flow is fully
restricted by fully closing the tester flow con-
trol valve.
8. Verify pump flow Under Load as follows:
A. Watch flow meter pressure gauge carefully while
slowly closing the flow control valve until 2000 PSI
(137.9 Bar) is obtained on gauge.
B. Record tester pressure and flow readings under
load.
9. Open tester flow control, set throttle to low speed,
and shut off engine.

10.The under load test flow reading (step 8.) should not
drop more than 15% when compared to no load test
flow reading (step 7.). 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. The gear pump is worn and should be repaired or
replaced
11.Disconnect tester and reconnect hydraulic hose.
