Chain Tensioner for timing chain suitable for Mercedes-Benz. The timing chain is an integral part of the combustion engine. As a connecting element between crankshaft and camshaft, it ensures precise synchronisation and often drives other components as well. The function of the chain tensioner is to keep the chain drive under tension at all times, including compensating for chain elongation due to wear by re-tensioning. Chain tensioners from febi are manufactured according to the specifications and standards of the original equipment manufacturer to guarantee a perfect fit and long service life.
