Abstract

A stem with a specially constructed groove and a snap ring is disclosed along with a method of forming the groove and assembling the snap ring whereby a snap ring is first assembled about a reduced diameter portion of a stem on which a support surface of larger diameter has been formed and a retention groove is then formed by peening over the top end of the stem to form a collar which becomes the upper wall of the groove and retains the snap ring about the stem.
