A NEW KNOB?
A NEW KNOB?

he tank commander’s knee
guard is there to protect him
from spent shell casings. But it
can’t do its job if the guard’s
lock assembly, NSN 5340-01-
428-7658, is broken.
The lock assembly has a
screw-in knob that’s used to slide
the locking pin back and forth.
When the knob vibrates loose or
snaps off, you can’t lock the
knee guard.
The knob isn’t listed in the
-24P-2 TMs, so most units order a
new $60 lock assembly. But you
can still get the knob with NSN
for
about
$3.50.
Keep the new knob on the job
by coating its threads with a dab of
sealing compound, NSN 8030-01-
158-6070, before screwing it back
in place. Then keep an eye on the
knob to make sure it stays put.

M1A2 Tank . . .
Pack LRUs
Right and Tight

M1-Series Tanks . . .
Knob missing? Lock won’t work
W
hen you mechanics take delivery of a
new line replaceable unit (LRU) for an
M1A2 tank, you don’t expect to receive it
in a flimsy cardboard box, do you?
If it came like that, you’d probably just
be shipping it back as damaged goods.
LRUs should
always
arrive in their ship-
ping containers to help prevent damage.
Guess what? That’s also true for dam-
aged LRUs that
you
ship back for repair.
If you don’t pack ‘em in their original or
new shipping containers, they may not
get where they’re going at all. Those that
do are damaged even further. What was
once a repairable LRU is then just an
expensive piece of junk.
When you get a new or repaired LRU,
always keep the container. You’ll need it
if the LRU ever has to go back for repairs.
If you’re missing a container, don’t just make do with whatever
you can find. Order a new container before trying to ship out an
LRU. Here are the M1A2 tank LRUs and their containers:
