A timing chain tensioner maintains appropriate tension in the timing chain system. Depending on the OE design, tensioners can use spring tension and/or hydraulic pressure to properly tension the system. The crankshaft drives the valvetrain via timing gears. Gear timing must be precise to ensure the valves open and close at the right time, for optimum engine performance. However, worn gears can cause timing to go astray and cause the engine to not start or run poorly. When it’s time to replace worn timing system components, depend on Cloyes for the OE quality timing drive components that will restore engine performance and reliability. Cloyes has been manufacturing timing components for over 80 years. It’s their only product line, which enables them to concentrate on maintaining the highest quality standards.
