ABSTRACT:
An apparatus for compressing a retainer ring to reduced assembly size and maintaining the compressed assembly size at an assembly location by internal containment of the retaining ring lugs is provided. The apparatus typically includes a compressing member for compressing the ring from the exterior and mandrel member disposed in the compressing member and around which the ring is compressed to assembly size. The mandrel member includes a lug-retaining groove into which retainer ring lugs having special flats are compressed and retained interiorly of the ring to hold the ring at reduced assembly size. The compressed retainer ring is carried to the assembly location outside the compressing member on the mandrel member and is stripped from the mandrel member for final assembly internally in a part.
