TM  10-8110-201-14&P b. Cleaning and Inspection (Exterior). (1) Use a mild soap and water solution and a stiff  bristle  brush  to  remove  any  foreign  matter  from the exposed part of the bearing plates (fig. 3-6) and the drum  assembly. (2) Inspect  the  interior  front  plate  for  cracks and evidence of leaks around the valve assembly adapter  threads. (3) Inspect  the  interior  rear  plate  for  cracks. (4) Inspect  the  drum  causing  for  cuts,  deterio- ration,  and  evidence  of  leaks. Do not attempt to tow, lift or transport partially filed drums, to which emergency repairs have been  applied. (5) If  drum  casing  requires  more  extensive repair,  notify  direct  and  general  support  maintenance. 3-8. Drum Casing Emergency Repairs (Using Type II Repair Kit). a. Repair  exterior  holes  in  the  drum  casing  great- ing than 3/8 inch (0.9525 cm) in length as follows: NOTE Use the 2 inch (5.08 cm) mechanical patch (10, fig. 3-7) for tears up to 1-1/2 inches (3.81 cm). (1) Roll  drum  over  to  position  the  torn  area  at the highest point of the drum. (2) Put  on  the  face  protective  hood  (2,  fig.  3-7) (fuel  drum  only). (3) Turn back the nut on the threaded shank of the 2 inch (5.08 cm) mechanical patch. (4) Grasp the flange with the fingers and insert the rubber portion into the torn area. Pull forward until the rubber portion is completely inside the drum. (5) Use the pliers (9, fig. 3-7) to tighten the nut on the threaded shank until the flange seals against the drum  wall. b. Use the 3, 5, or 7 inch (7.62, 12.70, or 17.78 cm) sealing clamps (4, 5 and 6, fig 3-7) for tears up to 6 inches (15.24 cm). (1) Position the tear at the highest point of the drum. (2) Put on the face protective hod (2, fig. 3-7) (fuel  drum  only). (3)  Slip  the  corn  loop,  at  the  end  of  the threaded shank, over the left wrist to prevent its loss on the inside of the drum. (4) Release  the  wingnut  on  the  threaded  shank to permit entry of the bottom half of the sealing clamp through the tear. NOTE Use knife (3, fig. 3-7) if necessary to lengthen tear to accommodate clamp. (5) Push  the  bottom  half  of  clamp  completely through  the  tear  and  pull  forward  to  tighten  it  against the inner wall of the drum. (6) Insert upper half of clamp in threaded shank and turn entire clamp until length of clamp coincides  with  length  of  tear. (7) Place  wingnut  on  threaded  shank  and tighten down to seal. Do not attempt to tow, lift or transport partially filled drums to which emergency repairs have been applied. (8) If  drum  casing  requires  more  extensive repair,  notify  direct  and  general  support  maintenance. 3-9. Swivel Plates and Shackles or D-Rings, Bearing Plates and Closure Rings. a. Use a mild soap and water solution and stiff bristle  brush  to  remove  any  foreign  matter  from  the exterior of the shackles or D-Rings, swivel plates, and bearing  plates. b. Inspect the shackles (fig. 3-6) for cracks and damaged  or  missing  screws. c. Inspect  D-rings  for  distortion  or  damage. d. Inspect swivel plate for cracks and mechanical binding. e. Inspect  closure  ring  and  bearing  plate  for  cracks and  loose  or  missing  capscrews. f. If  replacement  or  repair  of  parts  is  necessary, notify  direct  and  general  support  maintenance. 3 - 9
