REMOVAL

WARNING

Doors weigh approximately 100 pounds. To

prevent personal injury at least two

soldiers should handle door.

NOTE

Removal/replacement procedures for both left

and right hand doors are the same.

Remove (if installed) grounding straps (6, FIGURE 2-174) from hinge blades

(2) and from bulkhead.

Open door (1).

When loosening dogs in watertight doors,

those dogs nearest the hinges should be

loosened first. This prevents the door from

springing and makes it easier to operate the

remaining dogs.
