Slide Fasteners. Replace malfunctioning or damaged slide fasteners on the field pack, as neces-
sary. Remove damaged fasteners by carefully cutting off the fastener tape as close as possible to
the outer row of stitching holding the slide fastener. Trim any raveled yarns from the remaining
fastener tape. Attach a new fastener of appropriate length and type as specified in Table 21-2 and
Section Ill using type 301 stitching, size F thread and six to eight stitches per inch (2.54 cm).
Snap Fasteners. Replace missing, loose, or damaged snap fasteners. Repair damaged area
surrounding snap fastener sockets and studs prior to attaching new fasteners. A hole will be pre-
punched through the material before inserting the sockets or studs. The pre-punched hole will be
smaller than the outside diameter of the fastener barrel, so that the barrel must be forced through the
hole. The fasteners will be securely clinched without cutting the adjacent material and no more than
three splits shall occur in the button or eyelet barrels.
Drawcords and cord locks. Replace damaged, missing, or defective drawcords in lengths matching
the original construction. Drawcord ends will be heat seared and knotted. Replace cord locks of the
type specified in Section Ill, as necessary. The specific lengths are listed in Table 21-4.
Eyelets and washers. Replace loose or missing eyelets and washers as required. Remove damaged
eyelets and washers by carefully cutting them with diagonal wire cutters and not cut or damage the
webbing. Install new eyelets and washers of the type specified in Section Ill. Holes shall be
prepunched or drilled to receive the eyelets and shall be smaller than the outside diameter of the
eyelet barrel. Eyelets will be clinched without splitting and shall not damage the adjacent material.
Repair of binding tape. Overlap the binding tape using material specified in Section Ill; extending the
new tape at least 1/2 inch (1.27 cm) beyond the damaged area. Turn the binding edges under 1/2 inch
(1.27 cm) and stitch 1/8 inch (0.33 cm) in from the edge of the tape. Material lengths and widths for
specific applications are listed in Table 21-3.
Hardware. Replace damaged missing, or malfunctioning D-rings, double bar, and quick release
fasteners as necessary. Remove stitching holding damaged hardware or trim any raveled yarns
from torn stitching, Cut appropriate webbing specified in Section Ill, to the length indicated. Thread
hardware to be replaced through webbing. Sew webbing as in original construction and bartack as
appropriate.
Replacement of staves and lower back pad. When these items become unserviceable on the field
pack, they must be replaced with new or serviceable items conforming to the specifications listed in
Section Ill. These items are removed by sliding the staves out of their tunnel and the webbing slots of
the pad. Install serviceable items by reinstalling the staves.
