Dear Editor,
The M777A2 howitzer’s Chief of Section Display (CSD) panel, NSN 6625-
01-533-8823, is a very expensive piece of equipment. If you accidentally
drop something on it, the screen could crack. A new CSD panel will set your
unit back more than $43,000!
I’ve come up with a simple, inexpensive way to protect the CSD screen while
still allowing easy access to the buttons on the panel. Here’s how:
1.
Cut a thin piece of plexiglass to fit the CSD panel. I used a piece of scrap
plexiglass, but you can usually find it at your local home improvement store for
about $10.
2.
Lay the plexiglass on
the panel and use the black
rubber rim to secure it in
place.
3.
Outline the areas where
the panel’s buttons are
located with a thin-tipped
marker.
4.
Remove the plexiglass and
cut out the marked areas.

Mechanics, after
installing the final
drive U-joint bolts
on the M109A6 Paladin
or M992A2 ammo
carrier, there’s
one
more step!
You must
remember
to
safety-
wire
the
bolts!
Unless they’re safety-
wired, the bolts will
loosen and back out.
When that happens, the
U-joints come apart and
tear up the transfer or
transmission.
So
remember,
after you
tighten ‘em
down,
lace ‘em
up!
Something cracked
the CSD screen! That’s
gonna be a
hefty
bill!
Nuts!
