See if this part fits a specific vehicle.

Check Vehicle Fit

Litens Automotive is the original equipment supplier to Chrysler/Dodge/Jeep for this decoupling alternator pulley. This replacement pulley is also designed and produced by Litens and 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). Decoupling pulleys are engine specific and should not be interchanged with other types of pulley technology. The Litens OAD type pulley is designed to free-wheel in one direction and, with an internal spring and damping device, softly engage in the opposite direction. The OAD is designed as a sacrificial part of the front-end accessory drive system, protecting other belt driven component as well as the alternator. The correct decoupler pulley ensures smooth, quiet performance as well as increasing vehicle gas mileage. Under normal driving conditions, the original pulley will require replacement in approx. 45,000 - 75,000 miles.

Product Features:
  • Patented Original Equipment Design
  • Protects the alternator and other front-end accessory drive components.
  • Installation instructions included.
  • New plastic cap included with the OAD.
  • Tools Required - Litens recommends using an impact gun with a 17mm hex driver bit such as Snap-On P/N CPT110A
  • Professional mechanics can install this replacement OAD in approximately 2 hours. During alternator replacement, belts, tensioners, and routing pulleys should be inspected.
  • 53mm O.D.; 17mm I.D.; 49mm width; 6-Grooved running surface ; High-grade steel construction. 17mm Hex bit driver Included for ease of installation.

      Happy to help you Robert. This decoupling pulley does not come with the socket. You would need to have your own.

      With reference to your inquiry on the Litens Overrunning Alternator Decoupling (OAD) Pulley - Original Equipment Quality -part# 920810A, the pulley on the alternator may be the problem. However, without the presence of the vehicle we could neither diagnose the problem nor provide you with a 100% answer. I would suggest you to get assistance from a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem. For any further assistance, you may also call us at: 1-877-238-2623 or visit the nearest Advance Auto Parts store and one of our Parts Pros will gladly assist you with any questions or concerns you may have.
