COMPRESSOR DIRECT SUPPORT MAINTENANCE REPLACEMENT - Continued
0076-00
DECONTAMINATION
1.
After removal of a bad compressor from the refrigeration system, tip the compressor toward the discharge port to
drain sample of oil into a clear glass container.
WARNING
Avoid inhaling fumes and burns from any acid formed by burnout of oil and
refrigerant.
2.
If the oil is clean and clear, and does not have a burnt acid smell, the compressor did not fail because of motor burn
out. If a burn out is not indicated, refer to direct support troubleshooting WP 0047-00 for other malfunction causes.
3.
If the oil is black, contains sludge, and has a burnt acid odor, the compressor failed because of motor burn out.
Proceed to replace the compressor.
REPAIR
Wiring
1.
Remove the insulation to expose inch (1.27 cm) of bare wire on each side of break or damaged insulation.
2.
Insert the ends into a splice-connector; splice and crimp the connector to make firm electrical contact.
3.
Alternatively, heat-shrink tubing may be slipped over one end of the wire before splicing, then heated after the
splice is made and soldered so as to cover the spliced area.
4.
Be sure that no bare wire is exposed after the splice is complete.
5.
Replace broken terminal lugs with exact duplicates.
6.
Check continuity terminal-to-terminal.
