CUMMINS_Belt Tensioner_Seafaring Inc
The belt tensioner ensures that the belt delivers enough tension while driving, so that the belt can move the various pulleys that drive the engine components.
It is made up of four main parts – the base, tensioner arm, spring and pulley. The base holds the other parts, and the spring keeps the belt pulled tight. The pulley is what facilitates movement of the belt. The tensioner arm is found on the bottom of the tensioner, and if press on it, it will work against the spring, delivering enough slack so that can adjust or remove the belt.
