5-15. Vulcanizing Part No. 13216E9172.
a. Exterior Patch
Cleaning solvent, TT-M-261D (Methyl-
Ethyl-Ketone), used in surface coatings
and in protective coatings is extremely
flammable and is potentially dangerous
to personnel and property. Keep con-
tainer closed. Use in a well-ventillated
area as the fumes are dangerous if inhal-
ed. Avoid repeated and prolonged skin
contact. Flash point of solvent is 24° F
(4.4° c).
(1) Clean damaged area of all contaminants
and foreign matter. Wash with an approved
detergent solution.
(2) Buff area to be repaired; buff the drum wall
5 inches 13 cm) in each direction from tear.
Remove dust and rewash with MEK (Methyl-
Ethyl-Ketone) solution.
(3) Prepare patch assembly as follows:
(a) Cut a patch from 42171 stock. Cut patch
large enough to extend 3 inches (8 cm) from break
in all directions.
(b) Cut second patch from 42171 stock. Cut
patch 1/2 inch (1.3 cm) larger than second patch.
(c) Cut third patch from 42113 stock. Cut
patch 1/2 inch (1.3 cm) larger than second patch.
(4) Apply one coat of 3895 cement to the cord-
ed side of the third (large) patch and one coat to the
second patch. Allow cement to dry.
NOTE
Under normal atmospheric conditions
the cement will dry in 2 to 3 minutes. Ex-
cessive humidity will require longer dry-
ing time. Use the applicator brush in one
type of cement only.
(5) Position the two cemented surfaces
together, centering the smaller patch on the large
patch. Roll and stitch thoroughly.
(6) Apply one coat of 3985 cement to the re-
maining side of second patch and one coat of ce-
ment to the first (small) patch. Allow cement to dry
and position the two cemented surfaces together,
centering the smaller patch on the larger patch (fig.
5-12). Roll and stitch thoroughly.
(7) Apply two coats of 3985 cement to the area
around break (previously cleaned and buffed).
Allow cement to dry between coats (fig. 5-13).
(8) Apply one coat of 3895 cement to the patch
assembly. Apply to side with small patch. Allow to
dry and position the two cemented surfaces
together at break area. Roll and stitch thoroughly
(fig. 5-14).
