(6)
Tighten the wing nut to securely clamp the tank wall between the two plates. Tighten enough to stop
leak. If pliers are used, DO NOT exert extreme tightening that might strip the threads of clamp stud or
that might damage the tank fabric.

Emergency Repairs With Wooden Plugs
(1)
In emergencies, as an immediate temporary measure, the furnished wooden plugs may be used for
expedient sealing of small holes or punctures. (Fig. 3-2).
(2)
Select the size plug needed to fit (seal) the tank puncture, insert in the hole and twist clockwise until the
fit becomes quite snug and the tank leak is either stopped or slowed to the greatest possible degree.
Follow-up regular inspection should be made of the inserted plugs, as possible tightening of the plugs
may be necessary if the leaks resume. Later, if a leak is not totally stopped, the use of a small repair
clamp may become necessary.
(3)
The size of hole or tear will determine the size of wood plug to be used.
(a)
For holes (tears) up to approximately 1/2 inch in size, use the 3 inch long plug.
(b)
For holes (tears) up to approximately 1 1/2 inches in size, use the 5 inch long plug.

Tank Assembly
NOTE
This procedure consists of patching cuts and punctures in the tank fabric. If tank must be put back in
immediate service, or materials are not available, perform emergency repairs, paragraph 3-5.a or 3-
5.b.instead of this task.
There are three methods to repair tank fabric which holds water.
Preferred Method: Patches are used on both inside and outside of tank.
First Alternate: Single patch on inside of tank.
Second Alternate: Single patch on outside of tank.
Fabric which does not hold water needs only one exterior patch.
a.
Ensure that all components of the repair kit (ROCTAD) (Item 1, App. E) are present and tank is empty before
starting repair. See Table 3-3.
