Compressor Isolation Method: Removal

  1. Carefully remove service valves from compressor by unscrewing the mounting bolts. Do not disturb line connections and do not turn valve stems with valve assemblies disconnected from compressor (to prevent system discharge). Cap service valves and plug compressor openings to prevent entry of dirt and moisture.
  2. If compressor clutch is to be removed (for installation on replacement compressor), energize compressor clutch with engine NOT running and remove clutch mounting bolt from end of compressor shaft, then install 5/8-11 bolt in driveshaft hold and tighten bolt to loosen clutch from shaft with clutch energized, disconnect clutch lead. Remove drive belt and clutch.
  3. Remove service valve caps and shipping plugs from compressor valve ports and immediately install service valves on compressor using new "0" rings.
  4. Remove compressor mounting bolts and lift compressor off engine. Remove clutch field assembly from compressor (on early compressors with rotating field, remove brush assembly).
