ABSTRACT:
An assembly tool for closed, self-locking retaining rings includes an extensible and retractable, tubular, centering sleeve for centering the ring on a ram recessed relative to the sleeve. The sleeve is carried by a housing in telescoping relationship with the ram. One end of the sleeve is fashioned with a plurality of circumferentially spaced guide slots bounded by circumferentially spaced rigid guide and centering fingers that are operable to center the ring by engagement with the ring body and to pilot the tool by engagement with the member to which the ring is to be assembled. Adjustable stops may control the position of the ring in an assembly in axial relationship to the parts of the assembly.
