Diagram Ref 13

The tensioner blade maintains proper tension on the timing chain, keeping it securely in place as it runs between the camshaft and crankshaft sprockets. By guiding chain movement, it ensures smooth operation, accurate valve timing, and reduced friction and wear. It also minimizes chain noise, helping the engine run quietly and efficiently.

The tensioner blade is located inside the timing chain assembly. It is mounted against the chain path, where it works with the hydraulic chain tensioner to keep the chain properly aligned and tensioned throughout all engine speeds and loads.

Over time, chain tensioner blades can wear, crack, or deform due to constant stress, heat, and oil exposure. A failing blade may cause the timing chain to loosen, rattle, or fall out of alignment. This can result in inaccurate timing, loss of performance, or even major engine damage. Installing an replacement restores the correct fit and function. Ensures long-term reliability, smoother operation, and protection of engine health.
