  1. CONSTRUCTION


    1. The valve lash adjuster assemblies, which are located at the fulcrum of the No. 1 valve rocker arm sub-assemblies, consist primarily of a plunger, a plunger spring, a check ball, and a check ball spring.

    2. Engine oil supplied by the cylinder head sub-assembly and the built-in spring actuate the valve lash adjuster assembly. 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 created during the opening and closing of the valve. As a result, engine noise has been reduced.

      Tech Tips

      Valve clearance adjustment is not necessary because a valve lash adjuster assembly is used.
