ROCKER ARMS
DESCRIPTION
The rocker arms are made of stamped steel (Fig.
29).
OPERATION
The rocker arms are used as a link between the
camshaft and valves. As the camshaft rotates the
lobes of the camshafts apply downward pressure on
the rocker arms. This pressure is then transmitted to
the valves which causes the valves to open.
REMOVAL
(1) Disconnect negative battery cable.
