The magnetic A/C clutch disc and hub assembly has the following characteristics:

• The A/C clutch drives the compressor shaft.
• When battery positive voltage (B+) is applied to the A/C clutch field coil, the clutch disc and hub assembly is drawn toward the A/C clutch pulley.
• The magnetic force locks the clutch disc and hub assembly and the A/C clutch pulley together as one unit, causing the compressor shaft to rotate.
• When B+ is removed from the A/C clutch field coil, springs in the clutch disc and hub assembly move the clutch plate away from the A/C clutch pulley.
