Fan belt wear analysis
① ABRASION
Appearance: The backside of the belt appears shiny or glazed. In advanced stages, the fabric or even the cord becomes exposed and gets damaged.
Cause: When in motion, the belt makes contact with a foreign object in its path such as a flange or bolt. This may be caused by improper belt tension or by belt flutter (vibrations) on longer span lengths between two pulleys.
Solution: Replace the belt and make sure to observe the complete tracking of the belt as it revolves around the pulleys. Check the tensioner and ensure proper belt tension.
② DAMAGED OUTERMOST RIBS
Appearance: Sidewalls of the belt may appear glazed or the edge-cord may become frayed and ribs removed. A noticeable noise may result. In severe cases, the belt can get pulled into the timing belt drive causing catastrophic engine damage.
Cause: Pulley misalignment is a common cause of premature belt failure. Misalignment forces the belt to kink or twist while running, causing premature wear.
Solution: Replace the fan belt and make sure to realign the pulleys. Also check that the pulleys, pulley brackets and shafts are not bent or broken.
