Gates timing belt tensioner pulleys provide the rotating belt contact surface within the engine’s timing tensioner arrangement. Working with the tensioning mechanism, the pulley supports controlled belt movement through the camshaft drive system. This steel pulley uses a smooth backside contact surface, allowing it to run against the corresponding surface of the timing belt. Gates timing components are designed for OE-quality replacement, providing application-specific dimensions and mounting configurations. A correctly functioning tensioner pulley supports the belt’s intended path as the crankshaft drives the camshaft, making it a key component of the engine’s timing drive system.
