Claim Text:
1. A vehicle piston rail ring installer, comprising: an axially movable pusher arranged for axially moving a cartridge of piston rail rings and positioning an end rail ring of the cartridge of piston rail rings in a preinstall position; a radially movable pusher device arranged for radially engaging the end rail ring in the preinstall position and separating the end rail ring from the cartridge of piston rail rings by radially expanding the end rail ring into an expanded state, wherein the radially movable pusher device includes at least one pusher that engages the end rail ring on a radially inward side of the end rail ring and the at least one pusher radially moves outwardly to elastically expand the end rail ring radially to the expanded state to initially separate the end rail ring from the cartridge of piston rail rings; and a translating device arranged for radially receiving the end rail ring in the expanded state from the radially movable pusher device and then axially moving said end rail ring while in the expanded state to an install position wherein the end rail ring is in axial alignment with a piston groove on an associated piston and radially contracts into the piston groove, wherein the translating device includes at least two fingers that each define a groove for accommodating the end rail ring in the expanded state.
