DESCRIPTION
The Idler Gear with part number 3686909 is a component of a truck's engine that serves as an intermediate gear between the crankshaft and camshaft. Its primary function is to maintain proper timing and tension of the timing chain or belt. The idler gear rotates on its own shaft, which is supported by bearings, and helps to reduce friction by distributing the load across multiple teeth. It also helps to prevent excessive wear on other engine components by absorbing shock and vibration. Proper maintenance of the idler gear is crucial to ensure optimal performance and longevity of the engine.
