TIME CHAIN TENSIONER

This timing chain tensioner is suitable for engines in the Renault R4 with different engine sizes. The tensioner keeps the timing chain at a constant tension. This helps prevent chain jumping and limits wear on chain and sprockets. The tensioner works together with the guides in the timing system and supports correct engine timing. The part is intended as a replacement for a worn or damaged tensioner. Installation takes place inside the timing housing by a mechanic familiar with this type of engine design and the tolerances that apply to this application in regular workshop practice.
