Test
Note: Perform the 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).

When "POWER SHIFT PRES" is highlighted, press OK key (I).
Place the machine controls at the following settings: engine speed dial "10" and AEC switch OFF. Refer to Testing and Adjusting, "Engine Performance - Test (Engine Speed)" for engine rpm settings. Note: Press OK key (I) within 5 seconds after completion of Step 3.j in order to ensure high idle.
The "POWER SHIFT PRES" will now be displayed. Line 4 of the display will now change to a numeric value. These characters represent the power shift pressure (kPa).
Press left key (D) or right key (F) in order to increase or decrease the numeric value that is displayed on line 4 of the display. Pressing left key (D) decreases the power shift pressure. Pressing right key (F) increases the power shift pressure. Note: The value for power shift pressure on the monitor may not always match the pressure reading on the pressure gauge. Adjust the value on the monitor until the desired power shift pressure is attained on the pressure gauge
