Drive Chain: Description and Operation

PRIMARY DRIVE

The primary drive is a triplex chain transmission. A chain tensioner consisting of two spring-loaded, hydraulically damped tensioner pads is
located between the two sides of the chain. The oil trap of the chain tensioner housing is continually topped up with oil from the primary
chaincase. Non-return valves in the oil ways between the oil trap and the tensioner pad cylinders provide the hydraulic damping.
