Patent ID: 8491257

Claim:
A method of assembling a crank arm and vane assembly for a variable nozzle, comprising the steps of: providing a vane assembly comprising a vane joined to a vane shaft that extends from the vane and terminates in a distal end; providing a recess in an outer surface of the vane shaft at a location between the vane and the distal end; providing a crank arm having an aperture therein; inserting the distal end of the vane shaft into the aperture until the recess in the vane shaft is inside the aperture; and causing a retaining member associated with the crank arm to engage the recess in such a manner as to fasten the crank arm to the vane shaft in a substantially immovable manner, wherein the retaining member comprises a resiliently deformable portion of the crank arm that extends into the aperture in a relaxed condition, and the inserting step causes the resiliently deformable portion to be urged radially outwardly until the recess in the vane shaft becomes aligned with the resiliently deformable portion, whereupon the resiliently deformable portion springs back and engages the recess.
