DESCRIPTION
The Idler Gear (part number: 3686776) is a truck component that is responsible for controlling the timing of the engine's camshaft. It is a small gear that is located between the crankshaft and camshaft, and it helps to maintain proper tension on the timing belt or chain. The idler gear rotates freely and does not transmit power, but it plays an important role in ensuring that all of the engine's moving parts are synchronized properly. If the idler gear fails or becomes damaged, it can cause serious damage to other components in the engine, including the valves and pistons. Regular maintenance of this part is essential to keep your truck running smoothly and prevent costly repairs down the line.
