Abstract
A target wheel/rotor pre-assembly for a camshaft phaser. A phaser rotor includes a central bore. A target wheel axial extension having a plurality of barbs is entered into the bore to fix the target wheel to the rotor, both axially and rotationally, prior to assembly of the rotor into a phaser stator during manufacture of the phaser. Simple gauge blocks or a fixture can be used to index the target wheel to the rotor such that all such rotor/wheel subassemblies are substantially identical, to a high degree of precision. Alternatively, the axial extension may be formed without barbs, the extension inserted into the rotor bore, and then the extension immobilized as by stamping of the barbs, tack welding, or the like. For another example, the axial extension may be formed as a separate intermediate barbed retainer that engages both the rotor bore and the target wheel.
