c. Repair or Replacement. Parts that are within the
acceptable repair and replacement standards may be
reworked to remove a minor imperfection if it does not
impair the strength of the parts. The following are a few of
the more common repair procedures that may be used.
(1) Cracks. Parts that are cracked may be
repaired by welding as long as it does not distort or impair
the strength of the part. Heat-treated parts cannot be welded
or heated unless otherwise specified.
(2) Rust. Rust on polished non-mating surfaces
may be removed with a fine oxide abrasive paper and the
surface polished with crocus cloth. After repair remove all
abrasive deposits and rust by cleaning parts as specified in
(3) Threaded holes. Damaged threaded holes
may be repaired by retapping or chasing the hole. If this is
undesirable or ineffective, the hole maybe drilled oversize,
a suitable insert or bushing installed, and then drilled and
tapped to the original thread size.
(4) Sheet metal parts. Sheet metal parts that are
damaged may be repaired as long as there are no damaging
effects (refer to FM 43-2).
(5) Painted surfaces.
(a) Paint will be applied only for protection of
base metal, not to enhance the appearance of a dingy look-
(b) All exposed metal surfaces normally painted
shall be grit blasted or alkaline/acid cleaned, pretreated
using a wash primer MIL-T-704, or zinc/iron phosphate
MIL-T-704. After pretreatment, the container shall have
one coat of primer conforming to Specification TT-E-485
or TTP-636 and one coat of forest green paint conforming
to Specification MIL-E-52798. Allow overnight drying
d. Reassembly and Instillation. Reassembly and
installation procedures for the container are provided in the
appropriate maintenance portion of the manual. On con-
tainers numbered less than 12000, particular attention
should be paid to lubrication of moving door components
using graphite grease, (item 3, App. D).
Section III. REMOVAL AND INSTALLATION OF MAJOR COMPONENTS
3-6. General. This section contains instructions for re-
moval and installation of doors, plywood liners, floor and
roof. Tasks labelled 12000 and higher refer only to those
MILVANS whose data plates show a serial number of
12000 or larger.
a. Removal (containers numbered less than 12000)
(1) Release door lever (5, fig. 3-1) from seal plate
(22) and move door to open position.
(2) Support the door assembly and remove bolt and
nut (11) attaching door to door hinge (10). Remove door,
b. Removal (12000 and higher)
(1) Support and secure door (fig. 3-1.1).
(2) Remove four hinge plates (item 4) by grinding
weld securing hinge plates to door.
c. Installation (containers numbered less than
(1) Carefully position door assembly so that door
holes are aligned with holes in door hinge (10).
(2) Install and tighten attaching bolt and nut (11).
(3) Lubricate door strap bearings, latching mecha-
nism and hinges with graphite grease (item 3, App. D).
(4) Check operation of door for correct mating of
door opening surface with door gasket.
d. Installation (12000 and higher)
(1) Replace door, shim it and lock into position
using operating arms (items 6 and 8). Shims should allow
enough space under door for smooth operation. Be careful
of door gasket when shimming door. Hinge must be com-
pletely in contact with door.
(2) Weld hinge plates (item 4) to door.
(3) Unlock door and remove shims. Check opera-
tion of door for correct mating and swing.
