Mitsubishi FUSO®

The Upper Timing Chain Guide, also known as Part Number MK667257, is a crucial component in the engine of a truck that helps to ensure the proper timing and synchronization of the engine's internal parts. This guide is typically made of durable materials such as plastic or metal, and is designed to fit snugly onto the upper portion of the timing chain. As the chain rotates during engine operation, the guide helps to keep it properly aligned and prevents it from rubbing against other components. Overall, the Upper Timing Chain Guide plays an important role in maintaining the performance and longevity of a truck's engine.
