Timing Chain Pinion
Mitsubishi FUSO®

The timing chain pinion (part number QC000341) is a crucial component in the engine of a truck. It is responsible for synchronizing the rotation of the crankshaft and camshaft, ensuring that the engine's valves open and close at the correct time. The pinion itself is a small gear that attaches to the end of the camshaft and meshes with the timing chain. As the camshaft rotates, it turns the pinion which in turn rotates the timing chain, ultimately controlling valve timing. A worn or damaged timing chain pinion can cause serious engine problems, including poor performance and potentially catastrophic engine failure. It is important to regularly inspect and replace this component as necessary to ensure proper engine operation.
