A tool aligns a snap-ring with a sink-flange tailpiece of a garbage disposal, and is used to slide the ring up along the tailpiece outer surface to a groove. The tool expands the snap-ring, prior to installation on the tailpiece, by an expansion mechanism, to a diameter that is slightly larger than the outer diameter of the tailpiece. The tool receives a stack of conventional disposal components on the tool top end, so the user with one hand can raise the tool and the stack to the tailpiece, and the fingers and thumb of the one hand can push the expanded snap-ring upward to reach and snap into the groove. The expansion mechanism may be a tapered tool bottom end, an expander tab, and/or an adaptation wherein the tool is reduced in diameter to fit inside a relaxed snap-ring and then increased in diameter to expand the snap-ring.
