Rocker Arm Assembly: Description and Operation
ARMS-ROCKER
DESCRIPTION
The rocker arms (10) are made of stamped steel and serviced as an assembly along with the lifter. The rocker arm (10) also has a fracture point. This
fracture point is designed to prevent engine failure if the engine is not timed properly or the timing belt breaks suddenly.
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.
