(6) Connector
Disconnect connector (6) from solenoid valve (5) for the swing parking brake. Test Procedure
Start the engine.
Place the machine controls at the following settings: engine speed dial "10" and AEC switch OFF. Reference: Refer to Testing and Adjusting, "Engine Performance - Test (Engine Speed)" for engine rpm settings.
Place the hydraulic activation control lever in the UNLOCKED position.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F).
Slowly move the swing joystick and make sure that the swing parking brake is activated.
Move the swing joystick for a full SWING RIGHT. Measure the case drain oil. Refer to Table 1.
Return the joystick to the NEUTRAL position.
Stop the engine.
Connect connector (6) to the solenoid valve (5) for the swing parking brake.
Repeat this test procedure three times in order to obtain three measurements. For each test procedure, swing the upper structure to a different position.
