Camshaft, Lifters and Push Rods: Description and Operation

VALVE TRAIN
The LN2 valve train utilizes cast steel rocker arms with a roller bearing fulcrum. Motion is transmitted from the camshaft through the hydraulic roller valve lifters and the tubular pushrods to the valve rocker arms. The valve rocker arm pivots on a roller bearing in order to open the valve. The valve-train is of the net-lash type without provision for manual adjustment. All valve-train lash is taken up by hydraulic roller valve lifters.
