We've Got What It Takes. 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. This also includes compensating the elongation of the chain due to wear by re-tensioning. If the chain tensioner no longer works 100%, this has a negative effect on the other components of the chain drive. This can result in major engine damage. Quality by Conviction. Non-compliance with service intervals and the use of incorrect oils can greatly accelerate the wear of a timing chain and associated components such as the chain tensioner. 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. Supplied Complete. Repaired Non-stop. When replacing the timing chain, the surrounding components should also be checked for wear. This applies in particular to the guide rail, tension rail, and chain tensioner. In order for all these parts to work together perfectly, it is extremely important that they are manufactured precisely and with high-quality materials. febi offers complete timing chain kits for certain vehicle types which contain all the individual parts required for professional replacement.
