Solid Pulley vs OAP vs OAD™
This comparison of three leading alternator pulley designs demonstrates the danger of using the wrong type of pulley on a vehicle requiring an OAD™ pulley.
Note the severe level of belt drive vibration (see whiplashing belt
tensioner) when a SOLID PULLEY is installed on the belt drive system.
Similarly, the use of an "OAP" (ONE-WAY CLUTCH) on this application also results in significant belt drive vibration, causing NVH issues and wear of key components.
This footage shows a Litens OAD™ pulley on the same application. Note the smooth, efficient, low-stress operation of the belt drive system.
