f you don’t keep on top of them, dirt and dust have a funny way of building up fast.
A quick look inside the air cleaner boxes in your howitzer or ammo carrier provides
all the proof you need.
That’s because dust and grit collect all over the boxes even under the best
conditions. If you’re deployed, that dirt, sand and dust collect a whole lot faster.
When that happens, the air induction system exhaust fans just can’t remove all the
dust and grit.
So, next time you pull the air Flters for cleaning, clean the air boxes, too.
C
rewmen, when it comes to the fuel cap on your M109A6 Paladin, it’s all about
the seal.
Taking the cap off and on, exposure to the elements, and just plain old age take
a toll on the rubber gasket on the underside of the fuel cap. When the gasket wears
out, it no longer creates a good seal between the fuel cap and the Fller neck rim.
That
can
let
water
and
dirt seep into the fuel cells.
And here’s a news ±ash: The
engine won’t burn water or
dirt very well.
So take a good look at the
fuel cap gasket whenever you
refuel. If the gasket is torn,
cracked or just plain worn out,
replace the fuel cap. A new
cap comes with NSN 2590-
00-798-4056.
2.
Open the two plugs at the base of each air box and blow out all the dirt and
sand with low-pressure air—no more than 30 psi. You’ll have to remove the blower
motor hose bracket to get to the plugs on the Paladin’s left air box.
3.
If the dirt and sand have hardened—which is what happens if water gets mixed
in—you’ll probably have to break up the mess with a screwdriver or chisel before
blowing it out. Be careful not to damage the bottom of the air box, though.
Never
clean the boxes by hosing them out with water. That leads to rust, which
causes even more clogging problems.

Clean out any dirt on the panel under the air Flter.
