Lubrication for the Overhead
Lubrication for the wive train is supplied through separate drillings in the cylinder block. The oil flows through the
drillings and across the oil transfer slot in the cylinder head gasket. From the transfer slot, the oil flows around the
outside diameter at the cylinder head capscrew, across a slot in the bottom of the rocker lever support, and up a
vertical drilling in the support. From these drillings, oil flows through drillings in the rocker lever shaft to lubricate the
rocker levers. Oil flows through a drilling in the rocker levers to fill a trough cast into the top of the levers. The oil
from the trough lubricates the valve stems, push rods and tappets.
