You think so, huh? Well, maybe it would be a good idea to go
back and make sure those latches are screwed in all the way.
Leave it alone and that loose nut puts more stress on the surrounding nuts. They
may loosen as well and pretty soon you might lose the roadwheel.
Problem is, those roadwheel nuts are supposed to be tightened only once.
That’s why it’s a good
idea to use something to
mark the loose nut before
tightening. Then, when you
return to the motor pool,
you can get your mechanic
to replace the marked nut
with
NSN
5310-00-982-
6809.
Use a dab of paint or a
permanent ink marker to ID
the loose nut.
You see, if the two
latches that secure the
cargo hatch aren’t tight,
the hatch will bounce
up and down during
operation.
Enough
of
that bouncing will strip
out the latch bolts. Then
you can’t secure the
hatch at all.
So, keep those latches
tight and they’ll keep on
latchin’!

crewmen, when you
finished loading or
unloading your ammo
carrier through the
cargo hatch, did you
remember
to latch
the hatch securely?
Screw latch in

I sure wish
they’d learn
to securely
latch my
cargo hatch!
when you’re in the field and
you find a loose roadwheel
nut on your paladin or ammo
carrier, what do you do?
you
tighten
it, of
course.
Roadwheel
nut loose?
Mark it and
tell your
mechanic
we have a couple of loose
roadwheel nuts that need
to be replaced.
how am I
supposed to
know which
ones?!
