Cummins Belt Tensioner | 3691283

Description

The Cummins Belt Tensioner 3691283 is a crucial component used primarily for XPI fuel systems on EPA13 Automotive 15-liter ISX/QSX engines. This belt tensioner is responsible for maintaining the proper tension of the engine's accessory drive belt. By keeping the belt properly tensioned, it ensures efficient power transfer to various engine accessories such as the alternator, water pump and power steering pump among others. This helps prevent belt slippage and premature wear, ensuring the smooth operation and reliability of the engine's accessory drive system. The belt tensioner is equipped with a spring-loaded mechanism that automatically adjusts the tension to compensate for belt stretch, ensuring optimal performance and longevity of the drive belt and other engine components.
