ou have to store your tank’s basic issue
items (BII) somewhere, tankers, but
don’t stick ‘em just anywhere!
Some crewmen fill up the empty
space on top of the air induction sys-
tem’s precleaner. They figure there’s no
sense letting that extra room go to waste.
Problem is, that’s where your tank
gets the fresh air it needs to stay cool. If

M1-Series Tanks…
Step 1:
Check to see if your tank is
equipped with the pulse jet system
(PJS).
V-packs on PJS-equipped tanks
are self-cleaning. Trying to clean them
yourself will ruin the system.
Step 2:
Before removing non-PJS
V-packs, use a black marker or grease
pencil to label the filters 1, 2 and 3.
That’s so you can put the V-packs
back into the same slots after you
clean them.
Storing stuff on precleaner
cuts off air supply
Hand-brush dirt and dust from the ele-
ments. Never hit the V-packs against
anything harder than your hand. That
can dent the V-packs and then they
won’t seal out dirt.
Notify your maintenance folks as
soon as possible that you had to clean
the packs.
They’ll give ‘em a proper
cleaning.
Step 4:
Wipe any loose dirt or sand
out of the bottom of the air plenum box.
If you let enough stuff collect there, the
V-packs won’t seat properly.
Step 5:
Reinstall
the
V-packs.
Remember to put them back in the same
sequence that you removed them.
If the V-packs are put back in a differ-
ent sequence, they won’t line up with the
original compression points on the air
plenum box seal. That leaves gaps in the
seal and allows dirt to get to the engine.
Step 3:
After removing the V-packs,
get your mechanic to clean the filters
with the V-pack cleaning wand.
If a mechanic isn’t available, clean the
V-packs yourself by shaking them gently.
t’s a fact of life, tankers. If you operate your tank, the air filters—or V-packs—
are going to get dirty. And if you don’t clean ‘em right, the engine won’t get the
clean air it needs to operate. Here’s how to do the job right:
Use a grease pencil or
marker to number V-packs
Shake
V-pack
gently
the airflow is restricted, the engine over-
heats and burns up.
So find somewhere else to store those
items. When you do, one thing’s for cer-
tain: Your tank will breathe a big sigh of
relief.
