TM 55-8115-200-23&P (d) Install a wood insert treated for water resis- tance. The metal face may then be reglued and secured around the perimeter by wood screws 1/2 inch long, spaced every 3 inches. Delamination of the metal surface is accept- able if the door forms a water/air tight seal when closed and secure.  Pop  riveting  is  an  acceptable  means  of  patching  the door, as long as it does not penetrate the inner surface of the door. (e) Weld  the  repair  metal  around  the  entire perimeter with E6017 electrode, (item 1, App. D). (f) Paint repaired area in accordance with Speci- fication  MIL-T-704.  After  cleaning  and  treating,  apply  two coats  of  olive  drab,  rust-inhibiting,  semi-gloss  enamel paint (item 2, App. D). Allow overnight drying between coats. b. Water Test After Repair. After any major repair to an empty container, a stream of water from an 0.5-inch nozzle at 15 psig shall be applied to all joints and seams. No water  entry  into  container  is  permissible  after  repair. c. Door Assembly Repair. (Containers numbered less  than  12000). (1) To remove door or any integral part of door where it is fastened with HUCK pins or standard carriage bolts, use a cold chisel. Split HUCK collar or nut along hor- izontal  centerline  and  remove  pin  or  bolt  as  required. (2) After damaged door is repaired, check all exist- ing  bolt  holes  for  being  out-of-round,  distorted,  etc.  Where it is required, drill damaged and/or distorted holes to a larger diameter and insert a wood dowel pin of a sufficient diameter and 1 1/16 inches long and sand smooth. (3) Replace door or any integral part of door by placing replacement part in position and using as a tem- plate to drill 11/32 inch diameter bolt holes through door. Insert  required  HUCK  pin,  apply  collar,  and  tighten  with HUCK wrench. NOTE In lieu of fasteners, use 3/8-16 by 2 inch long carriage  bolts  with  nuts. (4) To replace a hinge and/or hinge pin, proceed as follows: (a) Burn weld off end of hinge pin and remove pin. (b) Remove fasteners securing hinge to door using a cold chisel. Split HUCK collar or nut along horizon- tal centerline and remove pin. (c) Check hinge bolt holes for being out-of- round,  distorted,  etc.  Where  required,  drill  damaged  or  dis- torted hole to a larger diameter and insert a wood dowel pin of  a  sufficient  diameter  and  1  1/16  inches  long  and  sand smooth. (d) Replace hinge by placing in position on door and using as a template to drill 11/32 inch diameter hole through door. Insert required HUCK pin, apply collar and tighten. (e) Install  hinge  pin  and  check  operation  of  door for  alignment.  Adjust  hinge  if  necessary. (f) Tack weld end of hinge pin. (5) Minor repairs to door sealing gaskets can be accomplished  by  applying  adhesive-backed  PVC  gasket tape to damaged area, or by splicing with new gasket material. To splice gasket, remove damaged area and replace  with  new  gasket  material.  Tape  splice  with  adhe- sive  backed  PVC  gasket  tape. NOTE Where  possible,  cuts  should  be  made  behind hinges  or  guide  plate  assemblies. (6) Replace  a  damaged  door  gasket  as  follows:  (fig. 4-2). (a) Remove  staples  and  aluminum  retaining strips that secure gasket to door edge and remove gasket. In some instances, it may be advantageous to remove the top and bottom lock-bar ends to facilitate removal and installation  of  gaskets. (b) Thoroughly clean all edges of door by sand- ing,  peening,  etc. (c) Stretch new gasket (item 5, App. D) over door edge. Make sure the larger lip of gasket faces the out- side of the door. New gaskets should be installed at ambient temperature of 70 degrees F (21 degrees C) or above. (d) Install  new  aluminum  retaining  strips  on  the inside channel of gasket and staple to door edge, with a staple  gun,  at  approximately  three  inch  (7.6  cm)  centers. Check operation of door for mating of gasket with door opening surfaces. If a hang-up and/or fold-back occurs, iron  out  gasket  by  inserting  a  piece  of  plywood  3/4  inch thick and 3 inches wide in the channel section of gasket and carefully apply heat to the outside surface with an open flame torch. Allow gasket to cool thoroughly before closing door tightly. ^4-2Change 4
