Camshaft, Lifters and Push Rods: Description and Operation

The valve train is a ball pivot type. Motion is transmitted from the camshaft through the hydraulic roller valve lifters and the tubular valve pushrods to the valve rocker arms. The valve rocker arm pivots on a ball in order to open the valve. The hydraulic valve lifters keep all the parts of the valve train in constant contact. The valve rocker arm stud retains the valve rocker arm ball with a locking nut. The valve rocker arm stud is threaded into the cylinder head.
