BRACKET (WELDED), BROKEN
Equipment mounting brackets welded to the hull sometimes break due to vibration or collision with obstacles.
Brackets
are needed to mount components and devices in locations or positions where they can be used to perform their required
function.
Mount bracket into place and secure by welding.
Limitations:
None
Personnel/Time Required:
•
2 soldiers
•
1.0 hour
Materials/Tools:
•
Rod, welding (item 51, Appendix C)
•
Welding equipment
Procedural Steps:
1.
Set broken portions of bracket in original position.
2.
Weld bracket in place.
3.
Elongate holes or slots in bracket to compensate for misalignment.
4.
Record BDAR action taken.
When mission is complete, as soon as practical, repair the equipment/system using
standard maintenance procedures.
SECTION III.
WIRING HARNESSES
3-7.
GENERAL
Wiring harnesses are normally replaced when extensive damage occurs.
Because of improvements of different
configurations, replacement harnesses from other vehicles of the same vehicle family may use some different style
connectors.
Try to obtain harnesses from an identical model if necessary, connectors can be exchanged with the
damaged harness.
The same procedure is followed to change a complete connector or splice a complete harness.
If a
wire is damaged, but the fault cannot be located, it should be replaced with a jumper wire.
3-8.
WIRING HARNESS, DAMAGED
Wiring harness repairs are generally accomplished using a series of single wire splices.
Establishing circuit continuity in a
bundle of wires is difficult because individual wires are not color-coded.
Wires must be identified before they are
connected.
Most essential electrical functions can be rapidly restored by using jumper wires.
