DRIVE BELT REPLACEMENT INTERVALS
Possible Causes of (NVH)
Insufcient belt tension may create a
high-pitched howl (squeal) or rasping
sound during engine acceleration or
deceleration.
Misalignment may cause a chirping
noise, especially at, or near, idle speed.
Rigid bracketing of accessories is a
must for reasonably vibration-free belt
spans. Some span vibration is to be
expected during the range of engine
speed and accessory loading.
WARNING
Failure to follow recommended application
information and recommended
procedures for installation, care
maintenance and storage of belts may
result in failure to perform properly and
may result in damage to property and
serious bodily injury. Make sure the belt
selected for any application is
recommended for that service.
