New Pump Needs New Bracket
T
he M2/M3-series Bradley’s engine
access door pump, NSN 4320-01-271-
0297, has been replaced by a new pump,
NSN 4320-01-432-6208. Since the new
pump is built longer and wider, it needs its
own mounting bracket, NSN 5340-01-
458-7289. Make a note in your parts TM
until it’s updated.
Those of you with basic model Bradleys
don’t have to worry. Your vehicles don’t
have an engine access door pump.
F
ire extinguisher bottles aren’t much good if they
can’t hold a charge. But leaking bottles are exactly
what some Bradleys and MLRS carriers are carrying.
Between Sep 99 and Feb 00, some FM 200 engine
compartment fire bottles, NSN 4210-01-463-0807,
came equipped with a defective elbow on the valve.
The elbow allows a slow leak that eventually empties
the bottle.
If your vehicle had new fire bottles installed dur-
ing those 6 months or if you’re unsure when the bot-
tles were installed, check them now.
If you’ve got a bad elbow, contact Windell Bishop,
Red River Army Depot’s customer service represen-
tative, at DSN 829-4816, (903) 334-4816 or (800)
442-0816 to arrange for a replacement elbow.

M2/M3-Series Bradleys…
Using Cover a No-brainer
S
ure, it’s less work to leave the M242 25mm chain gun’s cover, NSN 1005-01-171-
8316, folded up and out of the way when firing. The zippers, hook-and-pile tabs,
and tight space make installing the cover before firing a royal pain.
‘Course, the pain could be a whole lot worse if you
don’t
use the cover.
When you fire the 25mm gun, it produces a colorless, odorless gas called carbon
monoxide. The Bradley’s rotor fan pulls the fumes from the gun cover and sends
them out the plenum.
If the gun cover is not used, those fumes end up right there in the turret with you.
Limited exposure can cause headaches, nausea, shortness of breath, dizziness and
confusion.
Extensive exposure can kill you.
So make sure the gun cover is used
every time
the 25mm gun is fired. And make
sure the cover is in good working condition.
Eyeball the cover for rips and tears. Check the zipper and hook-and-pile tabs to
make sure they work. If the cover is damaged or missing, your Bradley is NMC.
