Cam Follower - a roller-type tappet operating in the engine valve train, between the camshaft and the pushrod. It rides on the camshaft lobe and transfers the lobe's profile into l inear motion, driving the pushrod that actuates the rocker arm to open the valve. The roller contact face reduces friction and wear at the cam-to-follower interface compared with a flat-faced tappet. Supplied as a single follower; renew as a matched set with the camshaft where lobe or roller wear is present. Show more
