How A Camshaft Lifter Tappet Follower Works?
Camshaft Lifter Tappet Follower Working of camshaft lifter Helpful Information A cylindrical rod is situated in the cylinder block or cylinder head which has oblong lobes or cams which push the intake and exhaust valves. This force is applied on the valve directly or through an intermediate mechanism such as a rocker arm, lifter (cam follower) and push rods are used to press against the valve for movement.
