2008 BMW 135i Alternator Decoupler Pulleys

This Litens supplied OAP is manufactured by the original equipment (O.E.) manufacturer. This replacement pulley is exact in all form, fit, and performance characteristics as the original equipment part (with the exception of not having the car manufacturer’s logo or part number applied to the part). Under rapid engine deceleration, the pulley disengages the alternator from the belt drive system, allowing the alternator to freewheel, re-engaging when the RPM increases. The OAP alternator pulley ensures smooth, quiet performance. The OAP is designed as a sacrificial part of the front-end accessory drive system, protecting other belt driven component. Under normal driving conditions, the original pulley will require replacement in approximately 70,000 – 90,000 miles. Litens is the world’s largest supplier of original equipment (O.E.) power transmission products.
