Meticulously manufactured primary chain tensioner which replaces the original component, however, it is additionally equipped with an hydraulic damper. This technology comes from agricultural machinery where it is used to tension drive chains. The shock absorbing effect minimizes chain lashing and thus improves the chain’s service life and lowers its running noise. Preload adjustment of the hydraulic damper is easy and can be performed with common grease pumps. The DynaMite primary chain tensioner works in both wet and dry primary housings.
Shipped with pre-filled grease chambers. Final adjustment with grease pump still has to be made. Pressure release via removal of grease fitting.
