Rocker arm & finger follower

Rocker arms and finger followers are components in engines that transmit 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 levers must operate precisely to ensure correct valve timing and efficient combustion. Regular inspection and lubrication of these levers is necessary to minimise wear and maintain engine performance. A faulty rocker arm or finger follower can lead to inaccurate valve timing and serious engine damage.
