I
t’s time to admit it: The torsion bars and shock absorbers on your ammo carrier
and A2-A5 howitzers just don’t cut it.
Some mechanics have wondered why they can’t substitute the sturdier torsion
bars and shock absorbers from the M109A6 Paladin instead. Well, you can stop
wondering.
After
thorough
testing, TACOM has
determined that the
Paladin torsion bars
and shocks are OK
to use in A2-A5
howitzers and the
M992A2. Use the
following info to
pencil in changes to
Figs 116 and 125 of
TM
9-2350-311-
24P-1 and Figs 167
and 177 of TM 9-
2350-293-24P.

Just replace
the old ones with
the new ones as
they fail.
W
atch where you put your feet
when you’re on top of your M109A6
Paladin, crewmen.
It takes only one misstep to come
down on the signal flare bracket,
NSN 1025-01-457-0527. If you’re
lucky, you’ll only bend the metal
clips that hold the signal flares. Then
you may be able to use some pliers
to bend the clips back up.
If you’re unlucky, the clips snap
off. Then you have no choice but to
replace the bracket with a new one.
That sets your unit back almost $70.
So save yourself some extra work
and your unit a repair bill. Keep your
feet clear of the signal flare bracket.

ow!
my
old
torsion
bars and shocks
are
shot!
not mine!
I’ve got
new
paladin shocks
and torsion
bars!
There’s no need
to switch out all
the torsion bars
and shocks at
once.
