Compressor Clutch Coil: Service and Repair

Compressor Clutch Coil and/or Pulley Rim Removal Procedure


TOOLS REQUIRED
^ J 39200 Digital Multi meter
^ J 41384 Clutch Plate Holder/Remover





IMPORTANT:
^ When servicing the compressor, keep dirt and other foreign material from getting on the compressor pants and into the system. Clean tools and a clean work area are essential for proper service. Keep the compressor and the pants clean at all times. Any parts which are to be reassembled should be cleaned with Trichloroethane, naphtha, kerosene, or an equivalent solvent. Air dry the parts and wipe clean with a lint-free cloth.
^ All repairs and procedures for the compressor must be performed after the A/C system refrigerant has been discharged and recovered, and after the compressor has been removed from the vehicle.
^ When the compressor is removed from the vehicle for servicing, drain and discard the oil remaining in the compressor. Add 90 cc (3.0 ft oz) of new refrigerant oil when the repairs are complete.
