Drive Belt: Initial Inspection and Diagnostic Overview
Inspection and Verification
1. Verify the customer's concern by operating the engine to duplicate the condition.
2. Inspect to determine if any of the following mechanical concerns apply:
Visual Inspection Chart
3. Inspect for drive belt cracking/chunking/wear.
4. If the concerns remain after inspection, determine the symptoms and go to the Symptom Chart. Under severe operating conditions (high
temperature, low humidity), drive belt rib cracking can occur at less than 96,000 km (60,000 miles). Drive belt rib cracking (cracks across
grooves):
-
is not a reason for concern.
-
has no detrimental effect on drive belt performance.
Cracks parallel to grooves are acceptable.
The drive belt is still perfectly functional until rib chunking occurs. Drive belt chunking is where the rubber material actually chunks out between the
cracks. A new drive belt should be installed if chucking occurs.
V-Ribbed Belt With Chunks Of Rib Missing (Not Acceptable)
5. If the concern(s) remains after inspection, determine the symptoms and go to the Symptom Chart. See: Symptom Related Diagnostic Procedures
