An electromagnetic clutch assembly (10) has a housing (12, 14) and a shaft (16) rotatably supported by the housing. At least one end of the shaft extends out of the housing. A clutch plate (22) is mounted on the shaft (16) for rotation therewith. An armature plate (20) is mounted in the housing (12, 14). A gear (24) is rotatable and slidably mounted on the shaft (26). A spring assembly (88, 89) extends between the clutch plate (22) and the gear (24) to bias the gear (24) out of engagement with the clutch plate (22). A coil assembly (18) is mounted on the shaft (16) for sliding movement therealong. The coil assembly (18) engages the gear (24). Energizing the coil assembly moves the coil assembly (18) into engagement with the armature plate (20) and responsively effects movement of the gear (24) into engagement with the clutch plate (22), coupling the gear (24) and the clutch plate (22). De-energizing the coil assembly (18) responsively enables the spring assembly (88, 89) to effect movement of the gear (24) out of engagement with the clutch plate (22), de-coupling the gear (24) and the clutch plate (22).
