ABSTRACT:
A finger follower type rocker arm has an outer body that engages the stem of an engine valve. Within the body is pivotally mounted an inner arm engaged and moved by the cam lobe of an engine camshaft. A latching pin normally causes the inner arm and outer body to act as an integral unit to activate the engine valve in a conventional manner. Selective withdrawal of the latching pin permits the cam lobe to move the inner arm in a free-wheeling manner without effecting movement of the outer body or valve stem, thus disabling the engine valve.
