Camshaft, Lifters and Push Rods: Description and Operation

A roller rocker type valve train is used. Motion is transmitted from the camshaft through the hydraulic roller lifter and the pushrod to the roller rocker arm. The rocker arm pivots on needle roller bearings and transmits the camshaft motion to the valve. The rocker arm pedestal locates in a slot in the cylinder head and the rocker arm is retained in the cylinder head by a bolt. The pushrod is located by the rocker arm.
