Mini Timing Chain Tensioner - Iwis 11317607551

Product Information

An Engine Timing Chain Tensioner preloads the timing chain to prevent slack in the timing chain system. Too much chain slack will result in derailment of the timing chain which could cause engine failure. Engine timing chain tensioners are typically oil fed so it is vital to verify you have adequate oil volume and pressure when troubleshooting the timing chain tensioner. Common failure systems include chain rattle or slap on startup, or camshaft/crankshaft correlation fault codes.

• Rattling or Clanking Noise: One of the most common symptoms of a failing timing chain tensioner is a noticeable rattling, clanking, or ticking noise, especially on startup. This is because the tensioner may no longer be maintaining proper tension on the chain, causing it to become loose and hit surrounding components.
• Check Engine Light: A failing tensioner can cause timing issues that may trigger the vehicle’s check engine light. Common faults codes will correlate to a camshaft/ crankshaft fault as these sensors will detect that the timing is off.
• Valvetrain or piston damage: As the timing being off significantly enough in an interference engine can cause the valvetrain to come into contact with the piston surface

About Iwis

Iwis was founded in 1916 by Bavarian businessman Johann Baptist to manufacture chains for two-wheeled vehicles, but by 1939 Iwis was making the precision chain solutions for engine and drive systems for companies like BMW and Skoda. Today Iwis is headquareted out of Munich, Germany with a workforce over 1150. The Iwis goal is "100% repeatability across 30 million parts manufactured each day" meaning their manufacturing process goal is perfection across every link they manufacture, be it the first or 30,000,000th link. With attention to detail like that it is no wonder Iwis is a worldwide leader in high-quality chain solutions.
