A hydraulic roller valve tappet (6500), providing automatic lash adjustment, rides on a camshaft lobe and transfers its up-and-down motion to the rocker arm (6564) through a push rod (6565). Rotation of the hydraulic roller valve tappets is prevented by the valve tappet guide plate (6K512) and valve tappet guide plate retainer (6C515). The rocker arms are pedestal-mounted and pivot on rocker arm seats (6A528) bolted to the cylinder head (6049). The valves are arranged alternately intake valve (6507)/exhaust valve (6505).
