How Does it Work?
- Provides the best combination of traction, speed of movement, load of the bearings and long service life.
- Powers various accessory groups in your engine.
How is it Made?
- May be only rubber or polymer throughout or may have fibers embedded in the polymer for strength and reinforcement.
- Made in a v-shape to track in the mating groove of the pulley so that the belt cannot slip off.
Why Does it Fail?
- Belt is over-tensioned.
- Tension loss caused by a weak support structure, lubricants being sprayed or spilled on belt, excessive sheave wear or belt load.
- Cracks in the belt.
- Excessive shock load, or exposure to excessively hot or dry locations.
What are the Symptoms of Failure?
- Unusual sounds.
- Excessive vibration.
- Signs of even wear, cracking, fraying or burned spots on the exterior of the belt.
What are the Implications of Failure?
