Dear Editor,
The only Army ground vehicle
authorized to use the portable
Halon 1301 fire extinguisher,
the M1-series tank. That’s
because the driver sits so low
that he wouldn’t survive a CO
2
discharge.
Unfortunately, you can find
the Halon 1301 extinguisher in
HMMWVs, Bradleys, and other
vehicles because most
soldiers don’t realize what’s in
the bottle.
While Halon 1301’s chemical
name—CF
3
BR—is listed on
the data plate, most soldiers
fail to make the Halon
connection. Therefore,
expensive and environmentally
unfriendly Halon 1301 gets
used in places where CO
2
will
work just as well.
We’ve solved this problem by
putting HALON 1301 decals on
all Halon extinguishers. With
the labels in place, the
extinguishers are easy to
identify and stay in M1-series
tanks like they’re supposed to.

T
ankers, keep your cotton pickin’ hands off the electromechanical fuel system
(EMFS) connector when pulling or installing the powerpack!
The connector is so delicate that using it for a handhold will break the pins.
That results in shorts in the
EMFS and problems with low en-
gine power and erratic RPM levels.
So resist the urge to grab what
looks to be a strong handhold. If
the pack won’t go in or come out
without extra pushing or pulling,
something’s not right.
Check your sling, lift points
and lift angle, then try again.
M1 Tank Hub and Axle Kit
T
he hub and axle parts kit, NSN 2530-01-270-7499, is no longer available for
the M1-series tank. Instead, order one each of the kit’s component parts: gasket,
NSN 5330-01-063-5798, and plain encased seal, NSN 5330-00-695-1178.
M1-Series Tanks . . .
Now that’s an idea that’ll stick!
Sergeant Jacobs was recommended for
a monetary award for his idea through
the SMART suggestion program.
M1A1 Spur Gear Set
Y
ou no longer have to order the M1A1 tank’s spur gear set, NSN 3020-01-216-
4507, in the commander’s weapon station asssembly as a matched set. You can
order the entire gear set, which includes the spline gear and helical gear sector,
or just the helical gear sector, NSN 3020-01-422-8566. Make a note until Fig 6
of TM 9-2350-264-24P-2 is updated.
