Dayco Australia offers the aftermarket the premium quality Nuline range of Overrunning Alternator Pulleys (OAPS). 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.

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. All Dayco OAP Pulleys are supplied with a new protective dust cap to maximise product life.

Note: Overrunning Alternator Pulleys require special tools for removal and fitment, Nuline have the necessary tools available.
