Product Details

Timing Belt (B139) by Cloyes®. As timing drive system experts, we’ve expanded our timing belt offering to provide our customers with the highest quality timing belts. No matter whether you need a belt, chain or a complete timing kit, Cloyes has the OE quality parts that will fit right and deliver optimal performance.

The crankshaft drives the valvetrain and balance shafts, on engines so equipped, via timing belts or chains. Belt and chain timing must be precise to ensure the valves open and close at the right time, for optimum engine performance, and the balance shaft weights are in the correct position, to eliminate engine vibration. However, worn belts/chains and sprockets can cause timing to go astray. A stretched or worn engine timing belt/chain can jump one or more sprocket teeth, causing the engine to not start or run poorly. On an interference engine, improper valvetrain timing could result in contact between pistons and valves, and severe engine damage. A stretched or worn balance shaft belt/chain could cause incorrect balance shaft timing resulting in severe vibration. When it’s time to replace worn timing system components, depend on Cloyes for the OE quality belts, chains and related 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.
