A snap ring substantially uniform corss section is placed within a groove in a rotor disk of a bladed rotor. Unbalance of the bladed rotor with the ring installed is determined. The snap ring is removed for grinding to correct the unbalance and reinstalled at the same location grinding on or near the rotor is thereby avoided.

A bladed rotor balance arrangement comprising: a bladed rotor having a circumferential axially extending cylindrical extension; an inwardly facing groove in said cylindrical extension having a rounded ring receiving surface at the root thereof around the inner periphery of said extension; a locking protrusion located on said extension adjacent to said groove at one location only; a resilient split balancing ring of initial substantially uniform cross section, formed to mate with said rounded ring receiving surface, and having an interlocking protrusion at one location only, said locking protrusion and said interlocking protrusion formed to interlock with each other; and said resilient split balancing ring removably located in said groove with said locking protrusion and said interlocking protrusion engaged, whereby said ring may be removed for balance grinding and replaced in the identical position.
