c
rewman, water collects in the hull of your Buffalo A2 like a rain barrel at the side
of a barn.
Water drips off wet boots and uniforms, trickles in from the top of the vehicle,
comes in from the wash rack, or seeps in through loose drain plugs during fording.
Here’s the Problem
Solid:
If you’re in a cold-weather
region of Afghanistan, the water in
the hull and under the floor plates will
freeze. Since water expands as it freezes,
lines and fittings are ruptured, causing all
kinds of damage.
Liquid:
Water under the floor plates
will rust the vehicle’s air brake valves and
just about anything made of metal.
Gas:
As temperatures go up, the water
evaporates and condenses on radios and
electronic gear. Enough moisture can
short out electronic equipment.
By the way, make sure any water drained from the hull goes into a drip pan and
is disposed of according to your unit’s SOP. That’s because any Fuid leaks, like
coolant, oil or power steering Fuid, can end up in the vehicle’s hull. So,
never
dump
contaminated water down a drain or let it run on the ground.
Also, you don’t want water to get back in through the drain plug openings. Make
sure you reinstall ’em before operation–and do it right. Plugs that are too loose will
vibrate free. And plugs that are too tight are hard to open and more likely to be left
closed when draining is needed.
So, apply a little anti-seize compound, NSN 8030-01-087-8254, to the threads
before installing the plugs. That lets you tighten the plugs enough to keep them from
vibrating loose, but makes them easier to open next time.
Just make sure you put the compound on each plug’s threads and the threaded
portion of the hull. That way, all the threads are coated and the plugs won’t stick.
Here’s the Solution!
RCV
Buffalo
A2…
Water
takes on
three
forms –
solid,
liquid
and
gas.
All three
create
problems
in your
A2.
Open the
hull’s drain
plugs on
the bottom
of your A2.
there are
three drain
plugs
you need
to open on the
BuFfalo A2!
if you
don’t,
you’ll
leave
water
behind!
There are
three
of
them, so
make sure
you open ‘em
or you’ll
leave water
behind.
There’s
one under
here…
…another
one here…
…and don’t forget the drain plug
above and behind the tow pintle.
