Valve train & chain drive systems
Mechanical and hydraulic chain tensioners with tensioner blades and chain guides dampen the vibrations from the timing chain. This reduces noise development and increases operating life. The camshaft runs at low friction in maintenance-free needle roller bearings or ball bearings.
In the valve train, rocker arms, finger followers, and end pivot rocker arms or bucket type tappets with mechanical or hydraulic valve lash adjustment elements ensure optimal valve performance.
