LOCATION/ITEM
HOUSING ASSY
1. Inspect the housing assembly for dents, gouges, cuts or tears, broken welds, and major
deformation. Remove panels as necessary to determine whether internal components such as
coils, wiring, piping or other components or sub-assemblies have been damaged. If damage is
apparent, leak-test all parts of refrigerant system and make an operating check of controls and
functional components. If the unit is functionally ok, repair the housing.
2. Straighten dents by using a sheet-metal hammer and back-up dolly, using care to avoid
stretching the metal more than necessary. Fill gouges with body putty, fiberglass-epoxy filler
or weld. Weld cuts or tears. Sand paint to a feather edge around the repair, and paint as
directed in TM-43-0139.
3. Inspect for damaged plate nuts and rivnuts.
