HYDROSTATIC PUMP EFFICIENCY TEST
This test can be used to check the operating
efficiency of the pump.
IMPORTANT: When connecting a flowmeter into the
pump circuit, make sure the meter is connected
properly and the control lever is stroked in the
direction being tested. If not, the hydrostatic system
and/or flowmeter may be damaged.
Efficiency Test Procedure
1. Raise the boom and rest on the boom locks.
2. Put the Service/Run switch in the “SERVICE”
position.
3. Disengage the parking brake.
4. Securely block the skid steer with all four wheels
off the ground.
CAUTION
Failure to securely support the skid steer could
result in movement of the loader during testing
causing serious injury or damage to the
equipment.
5. Raise the operator’s seat and latch in the raised
position.
6. Remove the step shield.
7. Remove the high-pressure line from the pump,
for the direction to be tested.
8. Connect the test hose from the fitting on the
pump to the inlet side of the flowmeter and the
line from the motor to the outlet side of the
flowmeter. Turn the pressure regulator valve out
on the flowmeter to zero pressure.
