f you spent any time at all in Southwest Asia, you know that sand gets into every-
thing. It gets into your hair, your clothes, even your food.
If your M109A6 saw action there, chances are your hydraulics fared no better.
And that means you’re probably facing an elevation cylinder failure.
As a precaution, have your mechanic drain the hydraulic fluid and change the
filters. Instructions start on Page 18-3 of TM 9-2350-314-20-2-2.
Before he starts, though, make sure the cannon tube is elevated and depressed
several times, the cab is traversed 360 degrees, and the rammer activated. That gets
any settled sand flowing so that it can be drained along with the hydraulic fluid.

Get the Sand Out.

M109-Series SP Howitzer,
M992A2 Ammo Carrier…
C
rewmen, when closing the engine access grille on your howitzer or
ammo carrier, make sure you stow the grille support arm’s quick-release
pin first.
If the pin, NSN 5315-00-419-0758,
and chain hang free, they get broken
or crushed when the grille is closed.
The next time you open the grille, the
support arm won’t be able to safely
hold it up.
The M109A6 Paladin and M992A2
now have an updated kit, NSN 2590-
01-470-3665, that beefs up the sleeve
that supports the grille in the open
position. It includes a new pin that’s
increased in diameter from 0.25 to
0.375 inch. If your vehicle is equipped
with the new kit, order a replacement
pin with NSN 5315-00-878-5269.
Installation instructions for the new kit will be included in an upcoming
EIR Digest. Ask your TACOM LAR for a copy.
