1.
Clean off the old seal and adhesive
completely. To do it right you’ll need a
lot of elbow grease—combined with a
rag, dry cleaning solvent and a wire
brush.
2.
Spread adhesive, NSN 8040-00-664-
4318, in the seal groove. Use enough to
hold the seal, but not so much that it
squeezes out around the seal. The right
amount of adhesive keeps the seal from
sticking to the airbox frame and ripping
loose every time you remove the pre-
cleaner.
3.
Apply a very light coat of adhesive to
the bottom of the new seal and press it
into the groove with your finger. Take
extra care not to twist the seal as you
put the rounded side in the mounting
groove. A twisted seal is not airtight.
4.
Let the adhesive dry completely
before you put the precleaner back in
place. Put a dab of adhesive on a piece
of paper. When it’s dry, the seal should
be, too.

Precleaner
Trees and bushes make a good hiding place for your
tank, but they also result in clogged air precleaners.
Leaves that fall on or near the air inlets get sucked
onto the precleaner. Enough leaves will cut off airflow
and lower power output.
If the AIR CLEANER CLOGGED
FILTER light comes on, make the pre-
cleaner one of your first checks.
While you’re there, take a close look
at the baffle seals. Cracked, torn or
missing seals allow dirt and oil from the
engine to clog the air cleaner assembly
element strainers.
NSN 5330-01-225-6106 gets a new
short seal. The longer seal is NSN
Next, eyeball the bottom precleaner
seal. If the seal is missing, loose or torn,
replace it. There are two different seals
available: NSN 5330-01-166-5798 and
NSN 5330-01-329-6614. The seal you
use depends on the type of precleaner in
your tank. Check your -24P-1 TM to
match the correct seal with your pre-
cleaner.
A new seal
is useless
unless you
put it on
right.

To operate at
peak performance,
the engine in your
M1-series tank
needs a lot of
clean air.
M1-Series Tanks…
They
screen out
sand and
dirt so that
only clean
air can get
through.
They also

that can dent,

Keeping air
clean is the job
of the seals
and filters on
your tank’s
air induction
system.
