An apparatus for positively engaging and releasing a roller clutch actuator in a two-way overrunning roller clutch system 10 includes an actuator ring 54 having a plurality of detents 58 for receiving a radially extending, reciprocably moveable plunger 60. In a preferred form, the roller clutch drive system includes an axle case 38 containing a complimentary pair of drive and driven rotary members. The drive member 46 includes an axially extending bore, and the driven member 48 has one end thereof disposed within the bore. The drive and driven members together define an axially extending annulus 51 which contains a plurality of axially oriented rollers 42 circumferentially contained therein by a cage 50. The cage maintains the rollers in uniformly spaced relationship, and includes a friction ring 52 preferably integral therewith. The actuator ring surrounds the friction ring in constant, resilient, frictional engagement therewith. A transversely extending cam member 70 moves transversely with respect to the plunger, the cam member including a cam surface 66 engageable with the plunger for selectively and reciprocably moving the plunger into and out of engagement with the detents.
