VIDEO: Are All OAD Pulleys The Same?
Andrew Markel explains why two overrunning decoupler pulleys (OAD) may look the same on the outside, but on the inside they may be different. The reason for this is that the OAD pulley is tuned for the engine, drive belt system and alternator. Sponsored by Litens.
VIDEO: What Is A Torsional Vibration In The Belt Drive And Pulley System?
Andrew Markel covers how the movement of the pistons create torsional vibrations in the belt drive system. These small changes in the speed of the crankshaft can cause vibration in the alternator and belt drive system. If the vibration goes unchecked, it could lead to belt wear and component failure.

VIDEO: Is Belt Tension Going Up Or Down?
With new fuel efficiency mandates, automakers are looking for every possible way to reduce drag on the crankshaft. Many automakers are reducing drive belt tension to not only improve fuel economy, but to extend the life of the belt. Andrew Markel explains how they are able to reduce tension while controlling vibration. Sponsored by Litens.

VIDEO: It Is Not Just The Belt That Wears Out
At 100,000 miles it is not just the belt that is worn, it’s the entire drive belt system. Failing to inspect and service the tensioner, pulleys and all the components the belt touches can cause premature failure of the new belt. Sponsored by Litens.
