REPAIR

1. Remove as much old gasket material as possible by pulling or scraping it away from the metal surface.

WARNING

Adhesive remover is flammable and the vapors can be explosive. Repeated or prolonged

skin contact or inhalation of vapors can be toxic. Use in a well-ventilated area, wear

protective gloves, and keep away from sparks or flame.

2. Use adhesive remover and a stiff brush to soften and remove old adhesive and gasket residue.

3. Fabricate all gaskets in accordance with the Parts Manual.

4. Coat all mating surfaces of both metal and gasket with adhesive. Allow both surfaces to air dry until the adhesive is

tacky, but will not stick to fingers.

5. Starting on one end, carefully, but firmly, attach the gasket to the metal.

6. Straighten minor dents and bent edges using common sheet metal repair procedures.

7. Straighten any slightly bent louver blades by hand.

8. See TM 43-0139 for touch-up or refinishing procedures.
