Abstract
A roller finger follower (RFF) wherein the shaft of the roller bearing is restrained in the follower finger by the overhead cam. Ends of the shaft are positioned in place in the follower finger by notches formed in the side walls of the follower finger. The notches restrain the shaft from axial movement. The cam in position over the RFF keeps the shaft nested in the notches. Further restraining means are disclosed to keep the shaft loosely nested in the notches in the follower finger before the cam is installed in position.
