Procedure for removal of damaged valves. With a sharp, narrow bladed knife, make a shallow cut
through the round rubber cover or patch which covers the valve assembly. The cut should be
made at a relatively flat angle to prevent cutting through the boot. Completely cut around the valve
assembly just inside the printed instructions, and remove the valve assembly, being careful not
damage the rubber of the boot. (Fig. 9-13.)
Replacement of valve assembly. An air release valve with rubber protective buffer, equal to
Schraeder valve No. 9917, should be used as the replacement valve.

Buff the rubber area on the boot where the old valve was removed with sandpaper or wire
brush.
Spread an even coat of Schraeder No. 338 self-vulcanizing fluid on the buffed area. Allow to
dry thoroughly (about 5 minutes).
Remove the polyethylene protective covering from the base of the new valve. Do not touch the
tacky surfaces.
Center the new valve assembly over the buffed area and press firmly in place. Roll the edges
of the valve assembly with a hand roller or stitcher.
Repair of peeled, loose, or separated eyelet hinge stay.
1. Apply two coats of adhesive to the exposed surface of the hinge stay that has peeled,
separated, or been broken.
2. Allow each coat of adhesive to dry until it becomes tacky (about 15 minutes).
3. Press together and clamp all surfaces; allow to dry for 1 hour.
9.Preparation for Reissue.
(1) After boots have been restored to a serviceable condition, replace worn laces. Single-lace the lace
through the bottom eyelet, double-lace through the second eyelet, and single-lace through the
remaining eyelets.
Attach an instruction tag to the lace of the right boot. Replacement laces are:
Laces, footwear, nylon, flat, both ends tipped, black (NSN 8335-00-945-3969).
Laces, footwear, nylon, flat, both ends tipped, white (NSN 8335-00-131-6538).
NOTE
Boots that have been prepared for reissue but are subject to temporary
storage should have masking tape affixed over the valve to prevent entry of
dirt, dust, and moisture, and to prevent the valve from rubbing against and
abrading other boots.
