Air Flow
The restricted airfow indicator on the driver’s panel will
light up when the air Flter is clogged. But i± you’re operating in
the desert, it’s a good idea to clean the Flter more o±ten—even
before
the indicator light comes on.
In the desert, plan
on
cleaning
the
air
Flter at least weekly—
and
sometimes
even
daily—depending
on
conditions.
Pay
attention
to
engine
per±ormance,
too.
I±
it begins to su±±er, a
clogged Flter could be
the reason.
Cleaning
Turn the precleaner upside down and shake it to remove dirt and sand. Then wipe
it o±± with a clean, damp cloth and set it aside.
Clean the Flter element by blowing out dirt and sand with low-pressure air—no
more than 30 psi.
Make sure you use air ±rom another vehicle, not your own. Running your Stryker
to build up air pressure will allow unFltered air into the engine.
On most Army vehicles you blow air ±rom
the inside o± the Flter elements out to get rid o±
dirt and sand.
However
, the Stryker air Flter
element is the exact opposite.
Direct a jet o± low-pressure air ±rom the
outside in
. That loosens sand and dirt and
allows it to ±all out through the center channel.
I± you don’t have compressed air available
in the Feld, shake and tap the element gently
with your hand to loosen as much dirt and
sand as possible. Don’t hit it against anything
harder—like the ground or the side o± your
vehicle—or you’ll damage the element.
Give the Flter a more thorough air cleaning
as soon as you can.
Removal
Be±ore you can clean a clogged Flter element, you’ll have to remove it. Here’s how:
Blow air from outside in
1.
Disconnect the scavenger hose from
the connector on the precleaner.
2.
Release the three latches that hold the
precleaner to the air cleaner housing.
3.
Remove the filter assembly from the
housing and turn it upside down.
5.
Inspect the gasket, NSN 5331-01-461-
1526, and filter element, NSN 2940-
01-460-4902. If they’re damaged,
replace them.
4.
Unscrew the
wingnut and
separate the
precleaner
from the
filter
element.

Stryker…
Don’t You
Forget the Air!
Drivers, your
Stryker needs clean
air and
lots of it
to
keep operating in
the desert.
So maintain
‘em by the
TM and take
careful note
of these tips!
The
only way
to
keep the clean
air flowing is by
practicing
good
air filter PM.
There are some
crucial
differences
between the
air filter used on the
Stryker and those used
on
other
vehicles.
glad
that
mission’s
over! I can’t
wait to get
cleaned up!
hey!
my
air
filter
could
use a gOod
cleaning, too!
