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.
