reather valves on the Buffalo A2’s front and rear differentials must be clean and open to
let off pressure that builds up in those assemblies.
If a breather valve is plugged, seals blow, gear
oil leaks out, and gears go, too.
Keeping the breather valves clean is simple: Twist
the valve’s cap to loosen any dirt stuck inside. Then
pull on the cap to make sure it’s moving freely. If
the cap won’t turn and pull up, get a new valve.
Make sure the new valve is good by blowing
into the threaded end. If you can’t easily blow
through the breather, it won’t do the job for your
equipment. The cap on a good breather opens a
little under ½ psi – almost no pressure at all.
Then give all breather valves the twist-and-pull
test after each operation in mud or heavy dust.
Your A2’s differentials will live longer if you do.
You
can’t
operate
the
SUGV
properly if you can’t see the micro-
display because of a scratched lens
on the glasses.
The lens gets scratched when the
micro-display gets shoved into the
protective fabric sleeve along with
the glasses.
To store the unit properly and not
scratch the lens, place the glasses
inside the protective fabric sleeve
with
the
micro-display
on
the
outside
of the sleeve.
If the lens gets scratched or the glasses
get
damaged,
replace
them,
not
the
complete heads-up display unit. It makes
the difference between 25 bucks for the
lens, 93 bucks for the glasses, or 4,000 big
ones for the heads-up display unit!
Here’s what’s available:
You’ll want to make a note of these NSNs, especially the lens, until they show up
in an update to TM 9-2350-397-13&P.
Operators, here’s a
quick
reminder
to keep in mind about
the XM1216 Small Unmanned
Ground Vehicle (SUGV).
