Description

With the increase in the amount of accessories requiring extra electrical power, such as GPS navigation systems and heating and cooling power seats, alternator freewheels are becoming popular on many late model vehicles due to increased alternator loads and engine torsional fluctuations.

Dayco OAPs allow the alternator to ‘freewheel’ when the belt speed drops and are engineered with one-way clutches that allows the rotational inertia of the alternator to “overrun” during any belt deceleration event. Dayco OAPs, which are designed for long service life, decrease drive belt vibration and reduce belt slippage during rapid acceleration or deceleration, resulting in reduced stress on the drive belt and other accessories as well as increased alternator and drive belt life.

Dayco OADs have one-way clutching capability which allows the OAD to isolate and dampen the drive from the alternator upon deceleration. Similar to Dayco OAPs, OADs reduce belt slippage during rapid acceleration or deceleration, reduce stress on the drive belt and other accessories and reduce belt noise, all while increasing alternator and belt drive life as well as improving the variation of drive belt tension.
