Accessory Drive Belt Concerns
CAUTION: Do not lubricate the accessory drive belt, accessory drive belt tensioner or
idler pulley(s) as potential damage to the accessory drive belt material construction,
accessory drive belt tensioner damping mechanism, accessory drive belt tensioner pulley
bearing and idler pulley(s) bearing may occur.
Cracking
Accessory drive belts are made from rubber which hardens with time and can develop
cracks. As the accessory drive belt runs on the back of some of the pulleys, the cracks are
opened up. Small cracks are not considered to be a failure of the accessory drive belt. Only
if the crack is deep enough to reach the bottom of the groove to expose the cord or any
chunks are found to be missing from the accessory drive belt, is the accessory drive belt
condition considered to be unacceptable.
1. 1. Check the accessory drive belt for cracks. If the damage exceeds the acceptable
limit, install a new accessory drive belt.

Chunking
Chunking describes the condition where long lengths of rubber become detached from the
ribs of the accessory drive belt. This is considered to be a failure of the accessory drive belt.
