Testing the Auxiliary Control Circuit - Hopper Tilt Cylinder Internal
Leakage
g292781
Test Procedure
Hydraulic System: Testing the Hydraulic System
Perform a hopper tilt cylinder internal leakage test if you identify a hopper tilt
and lower problem. This test determines if a hopper tilt cylinder being tested is
damaged. The hopper tilt cylinders must be tested individually.
Note: The hopper tilt/lower circuit operation can be affected by the hopper
tilt cylinder binding, extra weight on the hopper, and/or binding of the lift
components. Ensure that these items are checked before continuing with the
hopper tilt cylinder internal leakage test.
Note: When performing the hopper tilt cylinder internal leakage test, the hopper
should be attached to the hopper lift arms.
1. Park the machine on a level surface and tilt the hopper; refer to Operator's
Manual.
2. Switch of the PTO, shut off the engine, and set the parking brake.
3. Secure the hopper in tilt position.
4. Clean the area around the hydraulic hoses end at the barrel end of the
hopper tilt cylinder. Disconnect the hydraulic hoses from the hopper tilt
cylinder barrel end fitting.
