Applications
Alternator drive belts widely used in Automotive industry.
Alternator fan belt wear analysis
① GRAVEL PENETRATION
Appearance: Small pinholes are visible on the backside of the belt. Bumps may be visible and fabric around the holes can be frayed.
Cause: Granular gravel or pebble gravel is wedged between the belt groove(s) and pulley ridge(s). Cars where the engine protection shield is missing are likely to have this problem.
Solution: Check the entire drive and then replace with a Pioneer poly v belt, which is precision ground in the factory for a better pulley fit. Make sure the new belt runs on perfect pulleys. Install an engine protection shield.
② OIL CONTAMINATION
Appearance: The belt surface is flaky, sticky or swollen.
Cause: Oil and grease are a rubber compound's worst enemies, weakening the compound's bonds and making the belt soft and spongy. Eventually, such a belt will slip, create heat and fail.
Solution: Eliminate sources of oil, grease or chemical contamination. Replace the belt. Do not use belt sprays.
