Drive Belt Misalignment

Drive Belt Misalignment

Belt To Pulley Contact:

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 a new drive belt to avoid performance failure or loss of the drive belt.
With the engine running, check drive belt tracking. If the edge of the drive belt rides beyond the edge of the pulleys, noise and premature wear may occur. Make sure the 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 end 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.
