Abstract
A roller lifter assembly has a lifter body with a leg extending outwardly therefrom, a bar having a elongated slot formed therein, a first rivet having a head and a shank, a button affixed to the shank of the rivet so as to sandwich the bar between the button and the leg of the lifter body. The head of the rivet has a surface adjacent to the shank that bears against a curved inner surface of the leg of the lifter body so as to prevent the rivet from rotating. The shank extends through the hole in the leg and through the elongated slot of the bar. The rivet is positioned so as to as to be non-rotatable during the movement of the lifter bodies.
