HOUSING.
See paragraph 4-41 for inspection and service of the housing.
a" Repair.
(1) Repairs are limited to rework of broken or cracked welds,
straightening of bent or dented sheet metal and replacement of
handles, gaskets, insulation, and rivnuts and some small sheet
metal parts by drilling out rivets and installation of replacement
parts.
(2) Disassemble unit as necessary and make repair as
indicated.
(3) Gasket and insulation replacement.
(a) Use only gaskets, insulation, or name plates identified
in TM 5-4120-383-24P.
NOTE
An initial supply of adhesive is supplied as Item 2,
Section II, Expendable Supplies and Materials List.
(See Appendix E.)
(b) Remove as much old gasket or insulation material as
possible by pulling or scraping it away from the metal surface.
Acetone and methyl-ethyl ketone (MEK) are flammable
and their vapors can be explosive. Repeated or
prolonged skin contact or inhalation of vapors can be
toxic.
Use a well-ventilated area, wear gloves, and
keep away from sparks or flame.
(c) Soften and remove old adhesive and gasket residue,
using acetone or methyl-ethyl (MEK) and a stiff brush.
(d) Coat the mating surfaces of the metal and gasket with
adhesive.
Let both surfaces air dry until the adhesive is tacky
but will not stick to fingers.
(e) Starting with an end, carefully attach the gasket to
the metal.
Press into firm contact all over.
(f) Minor dents and bent edges can be straightened using
common sheet metal repair procedures.
(g) Should touch up or refinishing be necessary, see TM
43-0139.
