WARNING: BLOCK THE FRONT AND REAR WHEELS, AND APPLY THE PARKING BRAKE AND THE SERVICE BRAKE, OR
INJURY TO PERSONNEL CAN RESULT.
CAUTION: Limit engine running time to one minute or less with belts removed or serious engine damage will result.
NOTE: A serpentine drive belt decreases the usefulness of this test. In these cases, use a Vibration Analyzer (VA), to pinpoint accessory
vibrations. An electronic listening device, such as an EngineEAR, will also help to identify noises from specific accessories.
^
Increase the engine rpm to where the concern occurs.
^
If the vibration/noise is duplicated when carrying out this test, the belts and accessories are not sources.
^
If the vibration/noise was not duplicated when carrying out this test, install each accessory belt, one at a time, to locate the source.
