Rocker Arm Shaft

GENERAL INFORMATION
The shafts are retained by retaining caps and bolts. Four 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.

SHAFT SPRINGS
Rocker shaft springs are used on the intake shafts ONLY to obtain the proper clearance between the intake rocker arms and the spark plug tubes.
