Drive Belt: Testing and Inspection
Drive Belt Misalignment
Drive Belt Misalignment
CAUTION: Incorrect drive belt installation will cause excessive drive belt wear and may cause the drive belt to come off the drive pulleys.
Non-standard drive belts may track differently or incorrectly. If a drive belt tracks incorrectly, install it with an original equipment drive belt to avoid
performance failure or loss of drive belt.
With the engine running, check drive belt tracking. If the (A) edge of the drive belt rides beyond the edge of the pulleys, noise and premature wear
may occur. Make sure the (B) drive belt rides correctly on the pulley. If a drive belt tracking condition exists, proceed with the following:
^
Visually check the drive belt tensioner for damage, especially the mounting pad surface. If the drive belt tensioner is not installed correctly, the
mounting surface pad will be out of position. This will result in chirp and squeal noises.
^
With the engine running, visually observe the grooves in the pulleys (not the pulley flanges or the pulley forward faces) for excessive wobble.
Install new components as necessary.
^
Check all accessories, mounting brackets and the drive belt tensioner for any interference that would prevent the component from mounting
correctly. Correct any interference condition and recheck the drive belt tracking.
^
Tighten all accessories, mounting brackets, and drive belt tensioner retaining hardware to specification. Recheck the drive belt tracking.
