w
ater in your tank’s NBC system is like you trying to breathe mud—stuff stops work-
ing real quick!
You’re on your own with the mud-breathing thing, but keeping water out of the NBC
system will be a lot easier if you follow these tips:
Crewmen
Keep the air induction system
covered with a tarp whenever
the tank is not in use.
Never spray water toward
the air induction system when
washing the tank.
Operate the NBC system
when it’s raining and while
washing the tank. That lets the
system extract any water
before it can hit the filters.
Mechanics
If you suspect there’s water in the NBC system, remove the front NBC sponson box
access cover and open up the drain plugs.
During semiannual maintenance,
make sure you do the sponson leak
test like it says in your -20-1-5 TMs.
Pay special attention to the sides of
the hoses, tubes and connections. Use
a mirror to view hard-to-see areas. If
regular maintenance requires going
into the NBC sponson box, check the
components then, too.
here’s mud in your eye!

So when you hear
metal scraping on
metal, it’s probably
because something
on your tank needed
some lube a
while back…
Either you’ve
got a mouse
infestation…
…or some of
your oil can
points need
lubing.
Well, let’s just
say I
don’t
need
any cheese!
“There are
quite a few
oil can points
on your tank that get lube as needed,
not according to a schedule. “
So if the front
fender hinges
are sticking a
bit or the
driver’s seat
is starting to
squeal,
don’t
wait
—don’t even
hesitate.
Get out the
general purpose
oil (PL-S) and
give ‘em a few
squirts.
“You’ll
find ‘em
all listed
in Appendix
H of your
-10-2 TM.”
The squeaky wheel
is
supposed
to
get the grease,
crewmen.
