Claim 12:
13. An accessory drive system for an internal combustion engine, comprising:
an MGU pulley mounted to the shaft of a motor-generator (MGU) unit;
a compressor pulley mounted to a compressor shaft;
a pulley assembly mounted to a crankshaft of an engine, the pulley assembly including
a sheave rotatably mounted via a bearing to the crankshaft so as to be rotatable independent of the crankshaft, the sheave having a first set of spline teeth thereon,
a rotary drive member fixed to the crankshaft so as to rotate therewith, wherein the rotary drive member has a second set of spline teeth thereon,
a slider gear disposed for rotation about the crankshaft, wherein the slider gear has a set of slider gear spline teeth thereon and the slider gear is axially moveable between a torque cut-off position and a torque transfer position, wherein, in the torque cut-off position the slider gear spline teeth intermesh with the rotary drive member spline teeth but not the sheave spline teeth, thereby operatively disconnecting the sheave and the rotary drive member from each other, and wherein, in the torque transfer position the slider gear spline teeth simultaneously intermesh with the rotary drive member spline teeth and the sheave spline teeth, thereby operatively connecting the rotary drive member and the sheave to each other, and
an actuator connected to the slider gear to drive the slider gear axially between the torque transfer position and the torque cut-off position; and

a endless drive member interconnecting the sheave, the MGU pulley and the compressor pulley.
