Preliminary Information

When servicing the compressor, keep dirt or foreign material from getting on or into the compressor parts and system. Clean tools and a clean work area are important for proper service. The compressor connections and the outside of the compressor should be cleaned before any "On-Vehicle" repair, or before removal of the compressor. The parts must be kept clean at all times and any parts to be reassembled should be cleaned with Trichloroethane, naphtha, kerosene or equivalent solvent and dried with dry air. Use only lint free cloths to wipe parts.

The operations described are based on bench overhaul with compressor removed from the car, except as noted. They have been prepared in order of accessibility of the components. When compressor is removed from the car for servicing, the oil remaining in the compressor should be discarded and new refrigerant oil added to the compressor.

Minor repair procedures may be done on the car without discharging the system. Major repair procedures require that the system be discharged of refrigerant.
