A dual roller clutch assembly with cages and cam races that cooperate to assure both that the cages are properly installed to the cam races and that the cam races are properly assembled relative to each other. The same structure also retains the cam races and cages together as a secure subassembly. Stops molded to the cages prevent incorrect installation of the cages to the cam races by blocking axial insertion in the incorrect direction. Locating notches in selected cam race end faces prevent incorrect relative positioning of the cam race-roller cage subassemblies by engaging a two-sided rib on the cages only when the cam races are properly oriented. The same two-sided rib retains the cam races axially together.
