TM 55-8115-200-23&P D). (d) Paint repaired area in accordance with Specification MIL-T-704. After cleaning and treat- ing,  apply  two  coats  of  olive  drab,  rust-inhibiting, semi-gloss paint, (item 2, App. D). Allow overnight drying between coats. (e) If  necessary,  install  plywood  panel  (para 4-3). (2)  To  repair  the  sheet  metal  panels  of  an empty container when damage is major, i.e., large hole: (a) Remove paint from damaged area. (b)  If   necessary,   remove   plywood   panel (para 4-3). (c) Cut the damaged area such that a piece of metal can be placed over the damaged area (fig. 4-1) . (d) Apply repair sheet metal over all of the damaged area providing at’ least two inch overlap all the way around. (e) Weld  the  repair  metal  around  the  entire perimeter with E6017 electrode, (item 1, App. D). (f) Paint repaired area per subparagraph g (1), (d). (g)  If  necessary,  install  plywood  panel (para  4-3). 4-5. Corner Posts, Side and End Rails. a. Burn  out  damaged  section  (fig.  4-4)  being careful not to burn adjacent panels unless they too are to be replaced. b. Clean  burned  area  with  grinder  and  wire brush. c. Tack weld replacement section into place and check  for  deformation.  The  splice  plate  as  illus- trated in figure 4-4 shall extend for a minimum of 12 inches on each side of damaged area. d. Weld section and recheck for deformation. Section  III.  CONTAINER  FLOOR 4-6.  Floorboard  Replacement.  If  floorboard  is damaged, cracked or warped 10 feet (3 m) or more, replace the whole board (fig. 4-5); less than 10 feet (3 m) floorboard is to be spliced (refer to para 4-7). a. Remove self-tapping phillips head screws and remove  damaged  board. b. Caulk  area  where  exposed  floor  and  sills  meet. Place new board in position. c. Drill 0.221 inch diameter holes through wood and steel cross members. Make sure new holes are drilled in cross member. d. Using  self-tapping  screws,  seat  screws  in  posi- tion  and  drive  screws  below  floor  level.  Break  off  ex- posed  portion  of  screws  underneath  container  by using a piece pipe or equivalent as a lever. 4-7. Floorboard Repair. Repair a damaged floor- board section as follows: a. Saw out damaged portion of floor along face of moss member (fig. 4-6). Splice must span at least four  cross  members  and  angle  iron  attached  to  cross member  must  extend  beyond  and  be  attached  to  the adjacent floorboard on each side of splice. No more than three splices are allowed per container floor. b. Weld to cross member, a steel angle 1/8 inch thick by 1 inch by 1 inch. The angle iron must be at- tached to cross members by welding each end to pre- vent rotation and along the bottom by spotting two inch  welds  six  inches  on  center.  Cross  members must be sound (fig. 4-7). c. Caulking  is  an  acceptable  method  of  making the floor weather tight. d. Drill 0.221 inch diameter holes through wood, angle support and cross members. e. Using self-tapping screws, seat screws in posi- tion and drive below floor level. Break off exposed portion of screws underneath container by using a piece of pipe or equivalent as a lever. f. A  forklift  test  as  outlined  below  will  be  ap- plied if in the judgement of the inspector, any other forms  of  damage  or  signs  of  deterioration  exist which  might  indicate  that  the  container  floor  is structurally unsound. (1) Support the empty MILVAN Container on its  four  corner  posts  so  that  the  floor  cross  members are clear of the ground (approximately 6 inches). (2) Load a 4000 lb (1814 kg) lowmast forklift with 4000 lb (1814 kg) weight safely located at the end of the forklift tines. (3) Run  the  forklift  down  the  center  line  of the container to the forward end wall and back out. Continue this procedure for both the left side and right side of the container. 4-5
