Test Procedure (continued)
3. Clean the junction of the hydraulic hoses and straight fittings at the hydraulic
motor ( Figure 24 ). Tag the hoses to correspond with the motor ports (A and
B) then disconnect the hoses from the fittings. Cap the motor fittings to
prevent contamination from entering the system.

IMPORTANT
To prevent hydraulic tester damage, make sure that the oil flow
direction indicator on the tester is installed so the oil will flow from
the disconnected motor B port hydraulic hose, through the tester
and into the disconnected motor A port hydraulic hose.
4. Install the hydraulic tester (flow and pressure) in series with the disconnected
hoses.
5. Make sure the flow control valve on the tester is fully open.
6. Start the engine and run it at low-idle speed. Check for hydraulic fluid leaks
from the test connections and correct before continuing the test.
7. Set the throttle to full engine speed (3,600 rpm) . Use a non-contact
tachometer (phototach) to verify the engine speed.
8. Verify the pump flow at No Load as follows:
A. Sit in the operator’s seat, disengage the parking brake and slowly press
and hold the RIGHT motion control pedal at the full forward position.
