Cummins 5256546 Belt Tensioner

• A belt tensioner is a mechanical component use to maintain the proper tension in a belt, such as a serpentine or V-ribbed belt, within an engine’s accessory drive system. The tensioner is design to automatically adjust and maintain the tension in the belt, ensuring that it stays properly engaged with the pulleys and operates efficiently. Belt tensioners are commonly used in automotive engines, industrial machinery, and other belt-driven systems. The primary function of a belt tensioner is to automatically adjust and maintain the tension in the belt. It compensates for changes in belt length due to wear, thermal expansion, and other factors, ensuring proper engagement with the pulleys.
