1. A crank and linkage assembly for a turbocharger, comprising:
a first crank having a cylindrical first pin extending therefrom along a first pin axis and terminating at a distal end of the first pin, an outer surface of the first pin defining a circular first pin groove therein encircling the first pin axis, the first pin groove being spaced along the first pin axis from the first crank;
a linkage comprising an elongate member extending from a first end to a second end, the linkage defining a first through bore adjacent the first end, the first through bore extending along a first bore axis; and
a plurality of first fingers integrally formed and of one piece with the first end of the linkage, the first fingers extending parallel to, and circumferentially spaced about, the first bore axis, each of the first fingers joining with the linkage at a root end of the first fingers and having an opposite distal end, the distal ends of the first fingers defining hooks that project inwardly toward the first bore axis, the first fingers being elastically bendable such that the hooks move away from the first bore axis and such that a restoring force of each of the first fingers acts in a direction to bend the hooks back toward the first bore axis;
the first pin being received into the first through bore, the hooks of the first fingers being engaged in the first pin groove so as to resist withdrawal of the first pin from the first through bore, wherein the distal end of the first pin defines a taper for engagement with the hooks of the first fingers as the first pin is advanced into the first through bore, thereby forming a connection between the first crank and the linkage in which the first fingers extend from the root end to the distal ends in a direction away from the first crank and toward the distal end of the first pin.
