Dayco Automotive OAD and OAP
For automotive vehicle applications that include OAD as Original Equipment.
The Dayco OAD has a one-way clutching capability which allows it to isolate and dampen the drive from the alternator upon deceleration. These specially designed pulleys reduce belt slippage during rapid acceleration or deceleration and reduce noise and stress on the drive belt and other accessories. Also designed to increase alternator and belt drive life as well as improve the variation of drive belt tension, Dayco offers a full line of high-quality OADs where vehicle applications call for it. Proper tools must be used to remove and install OADs.
For automotive vehicle applications that include an OAP as Original Equipment.
Dayco OAPs are engineered with one-way clutches that allow 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 less stress on the drive belt and other accessories as well as increased alternator and drive belt life. Dayco OAPs are application-specific replacement parts. If a vehicle requires an OAP, the same type of pulley must be installed using the proper tools.
