Cracking/Chunking/Wear






CRACKING
Under severe operating conditions (high temperatures, low humidity), drive belt rib cracking can occur at less than 48,000 km (30,000 miles). Drive belt rib cracking is not a reason for concern and has no detrimental effect on drive belt performance. The drive belt is still perfectly functional until rib "chunking" occurs.





CHUNKING
Drive belt "chunking" is where the rubber material actually falls out between the cracks. The drive belt should be replaced if chunking occurs.

WEAR
Wear includes conditions such as fraying, glazing, etc. Fraying gives the belt a tattered look. Glazing will make the belt shiny. Determine what type of wear is evident and proceed to symptom chart.
