Compressor Clutch: Description and Operation

NOTE:
- Internal A/C compressor components are not serviced separately. The FS-10 A/C compressor is serviced only as an assembly. The A/C clutch, A/C clutch pulley , A/C clutch field coil and the shaft seal are serviceable.
- Installation of a new suction accumulator is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.







The magnetic A/C clutch has the following characteristics:
- It drives the compressor shaft.
- When battery positive voltage (B+) is applied to the A/C clutch field coil, the A/C clutch is drawn toward the A/C clutch pulley.
- The magnetic force locks the A/C clutch 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 A/C clutch move the A/C clutch away from the A/C clutch pulley.
