Abstract
Joint retention apparatus is disclosed for preventing axial end-play movement of the outboard end collars of track links on the opposite ends of the track pins of track for track-type vehicles. The retention apparatus is located inboard of the pin ends so as not to be exposed to wear from contact with the track guides of the vehicle and includes a pin groove formed about the pin, a link groove located at the inner end of the pin bore through outboard end collar of the link and a retention ring. The retention ring is transformed into a formed-in-place retainer when it is extruded into the retainer cavity formed by the pin and link grooves as the link is pressed onto the end of the pin during the track assembly process with the use of a track press.
