Lifter / Lash Adjuster: Description and Operation
Valve Train
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. Each lifter acts as an automatic adjuster and maintains zero lash in the valve train. This eliminates the need for periodic valve
adjustment.
