VIDEO: Combating Belt Flutter With Decoupler Pulleys

OADs help absorb small vibrations from the crankshaft that could produce belt flutter.

The average belt tension used today is lower, with vibration control, and the integration of the Litens OAD (or overrunning alternator decoupler). As a result, less tension increases the life of the belt by slowing down wear.

This has permitted OEMs to extend replacement intervals past 100,000 miles on some vehicles. Also, with less tension, the amount of power required from the engine to turn the belt-drive system is lower, improving fuel economy.

Decoupler pulleys combat belt flutter, as they decouple the alternator from the belt-drive system and help absorb small vibrations from the crankshaft that could produce belt flutter.
