Abstract

A tappet having a contiguous body, an outer wall and transverse web. The outer wall defines a cylindrically-shaped outer surface and a recess. The recess is disposed within cylindrical surface of the body. An alignment member is press-fit between two staked ends of the recess, which engage opposite sides of the alignment member. The alignment member extends outwardly from the cylindrically-shaped surface. A roller is mounted to the contiguous body at the cam contacting end of the tappet.
