Abstract
A crank and linkage assembly for a component of a turbocharger includes a linkage having an end defining a through bore, an inner surface of the through bore defining a linkage groove therein. The crank has a pin whose outer surface defines a pin groove. A generally polygonal retaining ring of elastically deformable wire is installed partially in the linkage groove and partially in the pin groove to retain the linkage on the pin while allowing the linkage to rotate about the pin axis. Vertices of the retaining ring are in the linkage groove, while sides of the retaining ring are in the pin groove. Once the retaining ring is pre-installed in the linkage groove, the assembly can be assembled by a push-to-connect process.
