Blow It Out
A better way to clean the air filter is with
compressed air. So if you have a little more
time and an air hose is available, go this
route.
When using compressed air, it’s a must
to wear goggles and gloves for protection.
Once you’re ready, use the air hose to
blow from the inside out to remove sand.
Keep the air pressure at 30 psi or less to
avoid tearing the filter.
Wash It Out
For more stubborn problems like heavy dirt, carbon or oil deposits, wash the fil-
ter element and use it again. Here’s how:
1.
Gently rinse away dust and sand from the filter element with clean, low-pressure
(no more than 10 psi) water.
2.
Soak the filter element in lukewarm water using general purpose detergent, NSN
7930-00-282-9699. Follow the instructions that come with the detergent. Use a con-
tainer large enough to completely submerge the filter element.
3.
Very gently agitate the filter while it’s still in the water.
4.
Rinse the filter element with clean, low-pressure water from the inside out.
5.
Set the filter aside in a dust-free area to dry completely.
6.
After the filter element is dry, shine a flashlight from inside the element and look
for tears or holes. If you spot any, scrap the filter. Holes can let dirt and sand direct-
ly into the engine.
Before reinstalling the filter element, wipe the inside of the air filter housing with
a clean, water-dampened cloth.
Air filters can only be washed twice. When it gets dirty enough for a third wash-
ing, replace it.
M88A1 Recovery Vehicle…
K
eeping your M88A1 gulping clean, fresh air is a tough job in the desert. All that
sand and dust will plug the air filter faster than you might think.
That means you’ll need to pull and clean the filter as often as possible. If you
don’t, pretty soon it’ll be your recovery vehicle that needs recovering.
Shake It Out
Sometimes you only have a few minutes between missions. But even that’s long
enough to shake some of the sand out of the air filter.
Pull the filter from the canis-
ter and shake it gently. Then
tap the sides with your hands to
remove sand and dirt. Never hit
the element against a hard sur-
face. That’ll ruin it.
After reinstalling the filter,
take a look at the dust cover
before you lock it in place.
Sand has a tendency to get
underneath the baffle, NSN
don’t get it out, that sand falls
right back into the air filter.
Unscrew the wing bolt in the
center of the baffle and remove
it. Pour out any accumulated
sand and then wipe the inside
of the dust cover with a clean,
water-dampened cloth, NSN
Make sure there’s a washer, NSN 5310-01-378-8714, under the wing bolt when
you put the baffle back in place. That keeps the baffle from vibrating loose.
