Dayco Alternator Decoupler Pulley 892012

Alternator Decoupler Pulley. (892012) by Dayco

Dayco ® OAPs (Overrunning Alternator Pulleys) allow the alternator to ââ¬ËSfreewheel' when the belt speed drops and they are engineered with one-way clutches that allows the rotational inertia of the alternator to ââ¬Åoverrunâ⬠� 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 ® OAPs are application-specific replacement parts. If a vehicle requires an OAP, the same type of pulley must be installed. Proper tools must be used to remove and install OAPs.
