Abstract
A roller finger follower includes an elongate body having a first side and a second side. A first end and a second end interconnect and space apart the first and second sides. The first and second sides define a first and second pin orifice, respectively. A roller is disposed between the first and second sides intermediate the first and second ends of the body. The roller defines a shaft orifice therethrough. An elongate shaft extends transversely through the shaft orifice and has a first shaft end and a second shaft end. The first shaft end is disposed proximate the first side and the second shaft end is disposed proximate the second side. The first shaft end defines a pin chamber therein, the second shaft end defines a shaft bore therein. The shaft bore is concentric with and intersects the pin chamber. A locking pin assembly is disposed within each of the shaft bore, the pin chamber, and at least one of the pin orifices. The locking pin assembly has a default position wherein the shaft is coupled to the body, and a decoupled position wherein the shaft is decoupled from the body. The locking pin assembly is switchable between the default position and the decoupled position.
