Abstract

A roller finger follower includes an elongate body having a first side member and a second side member. A bracket having first and second sides is associated with the body. The first side of the bracket is disposed adjacent an inside surface of the first side member of the body. The second side of the bracket is disposed adjacent an inside surface of the second side member of the body. A roller is disposed between the first and second sides of the bracket. The roller defines a shaft orifice therethrough. An elongate hollow shaft extends through the shaft orifice and couples the roller to the bracket. A locking pin assembly is disposed at least partially within the hollow shaft. The locking pin assembly has a first position wherein the shaft is decoupled from the body and a second position wherein the shaft is coupled to the body. The locking pin assembly is switchable between the first and second positions.
