Connect one end of test hose (44) to tee (15).
Connect 6000 kPa (870 psi) pressure gauge (20) to the other end of test hose (44). Test Procedure
Note: Perform each test for the drive pump and the test for the idler pump one at a time.
To prevent personal injury or equipment damage from failure of the hydraulic test equipment or associated circuit components because of blocked pump flow, make sure that the test equipment valves are fully open before starting the engine.
To prevent personal injury and/or equipment damage from failed lines or components while the hydraulic test equipment is returned to the open flow position, slowly open the hydraulic test equipment valve while monitoring the pump flow.If pump flow does not increase as the valve is opened, shut the engine off and determine what is preventing the pump from upstroking.
Start the engine.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F).
