TB 9-2300-378-14 (3) Install outrigger support plate as follows: WARNING Welding in the vicinity of fuel, oil and hydraulic fluid is dangerous. Place flameproof material between welding area and fuel tanks and surround components with wet rags or canvas to protect against weld spatter. Station a helper in the immediate area with an approved fire extinguisher before beginning welding operations. Failure to adequately protect against fire can cause injury, death or damage to equipment. NOTE All welds must be performed to MIL-W-46086 (MR), Method 1. Use austentic electrodes only (308 MOT 16 stainless or equivalent). Refer also to TM 9-237 Welding Theory and Application. For left side of tank, proceed as follows: (a) Obtain reinforcement plate 12252268 from kit and weld plate to number 3 outrigger inner support bracket (on left side of tank) and hull as shown in Figure 4-19. (b) Clean, prime, and paint plate and weld area. NOTE For right side of tank, proceed as follows: (c) Using cutting torch, carefully cut the support 8762618 from the hull and grind surface smooth (Figure 4-20). (d) Obtain plate 12252276 from kit and trim or shim to obtain a good fit in position shown in figure 4-21. After good fit is obtained, tack weld plate in place. Weld plate flush to hull in areas shown in figure 4-21. Do not weld curved area of plate since of passageway must remain for fuel overflow drainage. (e) Clean, prime, and paint plate and weld area. 4-31
