ABSTRACT:
An apparatus and a method is disclosed for configuring a spring arm retaining ring which is contained by a groove that is put into a bore, such that the concentricity of the ring to a male part which is installed into the bore is limited to an extent that allows the ring to enter a tapered bore leading to the ring bore, and compresses the outside diameter of the ring. The male part that is installed into the bore includes a configuration which cooperates with the retaining ring, and may or may not be a portion of the part, or assembled to the part. The combination of the ring disclosed and the cooperating portion allows a retaining ring to be installed by pushing the male part, that is to be retained in the bore, into the bore.
