M1-Series Tanks…
C
hange 3 to TM 9-1000-202-14,
Evaluation of Cannon Tubes,
is now available. So
what does that mean to you?
Good question. Appendix B contains
new criteria for proper inspection and con-
demnation of the M256 cannon tube’s
chamber area. To allow crews to do a good
inspection, a new chamber brush kit, NSN
1015-01-511-7872, was added to the BII of
TM 9-2350-264-10-2 (Mar 03 w/Ch 1).
Instructions for using the kit are found on
Page 3-251 of the -10-2 TM.
The chamber brush and instructions
have not yet been added to the M1A2 and
M1A2 SEP TMs, but the new inspection
requirement still covers those tanks. Make
sure you order and use the new chamber
brush kit, too.

if you want to take the easiest
route, order from this list…
if you’re
ordering a new
TNB from the
parts manual,
determine the tank
configuration…
if you’re replacing the TNB in a tank,
take a look at the nomenclature tag of
the old TNB and Order with that NSN.
There are
several
different
configurations
of M1A1 tanks
out there.
…then follow the
usable on codes (UOC),
part number, and NSN
from the parts manual
to select the
right TNB.

that mean
to
me?

better order me
the new chamber
brush kit.

So how do
you mechanics
know the
right
TNB to use with
a particular
tank?
There are
three
ways.
Pick
the one that
works
best
for you
the parts manual
lists
four
different
nsns!
And each one
of them uses
a
different
turret
networks box
(TNB).
hey, it says here
that Change 3 to
TM 9-1000-202-14,
Evaluation of
Cannon Tubes,
is
now available.
