Abstract
A cam follower having a clamp disposed on at least one end thereof. The follower includes two opposing sidewalls interconnected by a lower pallet. A roller is rotatably mounted to and disposed between the sidewalls via needled or journal bearings or other rotatable connection known in the art. A clamp is disposed about an end of the follower to induce compression force in the pallet and possibly act as the valve guide walls. The clamp increases the stiffness of the follower and induces compressive stress in the pallet area thereby increasing fatigue life. The clamp could also increase the length of the valve guide walls for better stability during engine assembly.
