Never underestimate the ingenuity of a determined good ole boy. With duct tape, baling wire and vice grips we can fix anything.
Years ago in Korea we went to the port to pick up some 900 series 5-ton cargos.
One of them had a leaking pancake seal in the air brake chamber. When the brakes were released the air would come out faster that the compressor could keep up.
Our wrecker was already hooked up to a truck that would'nt start.
Our 2nd LT maintainence officer wanted to leave the truck and come back the next day (Sat) which would have crimped our weekend.
This was a 5 hour drive through Korean traffic and I didn't want to do that again.
With the LT watching in awe I caged the brake, unscrewed the airline, filed a dime down with my Leatherman tool, dropped it in the brake line and tighened the line back down.
No air leak!!
I drove the truck back to the motor pool and we fixed it Monday.
That Louie never questioned anything I did after that as far as "field expedient repair went".
For reasons best left unstated I was known as Sgt. Bilko while I was in that unit.
