ENGINE UNIT


  1. CONSTRUCTION


    1. The valve lash adjuster assembly is located at the fulcrum of each No. 1 valve rocker arm sub-assembly. The valve lash adjuster assembly consists primarily of a plunger, plunger spring, check ball and check ball spring.

    2. The valve lash adjuster assembly is actuated by the engine oil, plunger spring and check ball spring. The oil pressure and the spring force that act on the plunger push the No. 1 valve rocker arm sub-assembly against the cam, adjusting the valve clearance. This reduces the engine noise that is created during the opening and closing of the valve.
