  1. CONSUTRUCTION


    1. Simple sleeve-type chains are used for all chains. On a sleeve-type chain, the tooth flanks of the sprocket always touch the fixed sleeves at the same point. It is therefore particularly important for such chain drives to be correctly lubricated. While having the same pitch and breaking force, sleeve-type chains have a larger link surface than the equivalent roller-type chains. A larger link surface delivers a lower link surface contact pressure and thus less wear in the links.

    2. The timing chain is lubricated by the oil No. 2 oil nozzle sub-assembly.

    3. The chain tensioners use an oil pressure to maintain proper chain tension at all times. The chain tensioner suppresses noise generated by the chain. The oil in the chain tensioner achieves directional damping by means of a non-return valve.
