The armature shaft further comprises a solid cylindrical member provided with spiral spline grooves for engagement with the normal clutch and pinion drive assembly, the solid cylindrical member being received coaxially in the open end of the tubular member with portions of the open end being staked into the spline grooves to combine the members into one shaft, the portions of the open end not so staked providing an axial stop for the clutch and pinion drive assembly.
