Engine control using a timing chain is an alternative to the timing belt. Asian vehicle manufacturers also use this variant in some engine types.

Timing chains are maintenance-free and can last for up to 300,000 km. Nevertheless, it is essential to check the chain drive to prevent engine damage, since both the clamping and guide rails and the chain tensioner are subject to wear on account of mechanical stress.

Rattling noises or out of round engine running are signs of a worn timing chain that then has to be replaced by a new one.

Herth+Buss JAKOPARTS supplies complete timing chain kits for this situation. The kits, which are specially adapted to each engine, contain all the relevant replacement parts such as chain, tensioner, guides, gears and gaskets.
