Avenger Missile System…
Dear Editor,
Every Avenger unit has trouble with soldiers
stepping on the hand station when they climb in
or out of the turret. That breaks the rivets
that hold the station's bracket to the turret.
According to TM 9-1440-433-24P, the
bracket is not repairable locally, which means a
long trip to depot.
We've had success replacing broken rivets with
blind rivets, NSN 5320-01-015-6896. These
rivets are .124 to .128 inch in diameter so you
must redrill the rivet holes slightly larger to install
the new rivets. But we've found the rivets do a
good job of keeping the hand station in place.

Editor's note:
A riveting idea. Thanks.
Tighten all the screws holding the
circuit card racks.
If screws are loose,
the racks are loose. Bumps in the road
can unseat the circuit cards and then you
get faults when you power up the radar.
Check that all doors are latched tight.
You
don't want a door banging back and forth during
travel and letting in dust and rain. Just a little dust or
rain can cause big problems inside the radar. Always
keep the inside of the radar clean and dry. The easi-
est way to do that is to keep the doors shut as much
as possible whether you're traveling or sitting.
Carefully fold up the shroud.
If you
don't fold it properly, its buckles can
puncture the shell of the radar, which
can let water get at the expensive elec-
tronics inside. It's best to have three sol-
diers doing the job—two folding the
shroud manually and another on the
ground making sure they've got it folded
correctly. The TM says two is enough,
but the extra set of eyes will help get it
right. Once the shroud is completely
folded flat, make sure all its latches are
locked in so the shroud can't bunch up
during travel and damage the roof cover.

care of the
problem.
there
are a few
things
we need
to do
first
to
prepare
you for
travel.
if you don't care-
fully prepare it for
travel, you could
arrive at your des-
tination with a radar
that can't radiate.
Buckles can puncture shell

that was my
hand station you
just stepped
on! that’s a
depot fix!
Don't expect to
just be able to
hook up your

and hit the road.
