352-4681: Belt Tensioner

Description: The Belt Tensioner consists of a spring-loaded pulley or an idler pulley mounted on an adjustable arm or bracket. The pulley is designed to provide a constant force against the belt, compensating for any slack that may occur due to belt wear, temperature changes, or other factors. The primary function of a belt tensioner is to ensure that the belt remains tightly stretched around pulleys allowing efficient power transmission and preventing slippage. By maintaining the correct tension, the belt tensioner helps optimize the performance and lifespan of the belt and the overall system. Attributes: • Keeps the fan drive belt at the correct tension. • Keeps the belt engaged with the pulleys, preventing slippage or disengagement. • Helps dampen vibrations and shocks transmitted through the belt. Applications: The Belt Tensioner is used to maintain the proper tension of the belt that drives the cooling fan and is mainly used in Cat 627, 627H, 627K, 637, and 637K Wheel Tractor Scrapers, C32, and XQP1100 Generator Set, C9.3 Engine (Piston), C9.3 Engine-General Platform (C9), R2900 Wheel Loader, XQP1100 Special Application - No Pin.
