Rocker Arms and Shafts

DESCRIPTION
The rocker arms are made of light weight die-cast with roller type follower operating against the camshaft (Fig. 5). The valve actuating end of the rocker arms are machined to retain hydraulic lash adjusters, eliminating valve lash adjustment.
The shafts are retained by the camshaft bearing journal caps. Four rocker shafts are used, one for each intake and exhaust rocker arm assembly on each cylinder head. The hollow shafts provide a duct for lubricating oil flow from the cylinder head to the valve mechanisms.
