Rocker arm & finger follower

Rocker arms and finger followers are components in engines that transfer the movement of the camshaft to the valves. Rocker arms act as levers and tilt to open and close the valves, while finger followers run directly over the camshaft and actuate the valves.

Both types of lever must work precisely to ensure correct valve control and efficient combustion.

Regular inspection and lubrication of these levers is necessary to minimise wear and maintain engine performance. A defective rocker or cam follower can lead to inaccurate valve control and serious engine damage.
