ABSTRACT:
A drive assembly for rotating a shaft of a pulley-driven device is disclosed together with a method of making the drive assembly. The method includes the steps of forming a pulley of lightweight non-ferrous metal having a web portion, forming a radially inward portion of the web portion into an axially extending annular portion, mounting a connecting ring of ferrous metal having an annular groove in an interior end surface thereof over the axially extending portion of the web portion so that a free end of the axially extending portion extends adjacent the annular groove, cold-forming the free end to fill the annular groove, welding a hub of ferrous material to the connecting ring and machining a central axial bore through the web portion and the axially extending portion thereof and the hub.
