The batteries are held in place
with four J-hooks. But if the nuts that
lock down the J-hooks come loose,
your batteries will be bouncing all
over the place. That leads to spilled
electrolyte, shorts and maybe even a
cracked battery!
When
checking
the
batteries
during PMCS, take a close look
at the J-hooks, too. If the nuts are
loose, tighten them. If the J-hooks
are missing, you’ll probably Fnd
them in the bottom of the battery
box. If not, order new ones.
NSN 5306-01-190-2193 brings the larger J-hook. The smaller one comes with
NSN 5306-01-185-7071. NSN 5310-00-880-7744 brings 100 replacement nuts.

hen you’re driving along in your HMMWV, what you don’t see can hurt you.
That’s why it’s important to properly position the passenger and driver’s side mirrors
before you hit the road.
Most drivers pivot the mirror frames in and out and pivot the mirror itself within
the frame trying to get the best view possible. But what they forget is that the mirror
can also be moved a third way.
Depending
on
the
type
of
HMMWV
you’re
driving,
you
may also need to slide the mirrors
farther out on the frame. Mirrors
that sit too close to the doors can
be blocked by what’s on the back
of your vehicle.
Adjusting a mirror is easy. Just
loosen the top and bottom clamp,
slide the mirror in or out, and then
retighten the clamps. You’ll be a
lot safer when you can see what
you would have missed.

ooch! ow!
my
poor batteries are
getting bounced all
over the place!
I
still
can’t see
a
thing!
try pivoting
that mirror
out a little
bit more.
I
already
tried
that!
there’s got to
be a better way
to see what’s
behind us!
