M1114 HMMWV
Underbody Screw
The hex screw for your M1114’s front
passenger side underbody shown as Item 11 in
Fig 194 of TM 9-2320-387-24P has the correct
part number. The NSN is wrong, however.
Replace it with NSN 5305-01-436-6377.
Fiber Optic Cable NSNs
Order 300 meters of CX-13295/G ±ber optic
cable with NSN 6020-01-220-5435. Order
1,000 meters with NSN 6020-01-208-1147.
Upgrading M7 FRS
If your M7 forward repair system (FRS) has a
serial number from 0001 to 0743, you need to
upgrade its tool load and/or data plate. M7’s
with tool load P/N SC4940-95-E41 (formerly
P/N RIA149000), which is Granger, need to get
tool load SC4940-95-E42, which is Snap On,
and a new data plate, NSN 4940-01-533-1621.
If you already have SC4940-95-E42 (Snap
On), you just need the new data plate. To
receive the tool load and/or data plate, send
TACOM-RI the following info:
•
M7 serial number
•
unit name
•
ship to address
•
POC with phone number and email
Email it to Larry Rigsby at

Helmet Harness Tester
ALSE folks, here’s some good news! Your
integrated
helmet
and
display
system
(IHADSS) has a new tester for the helmet’s
new IR harness. NSN 4931-01-534-1228 brings
you the tester. You can use the tester on the
old harness as well.
Communication Earplug Kit
All new HGU-56/P helmets now come with the communication earplug (CEP) already installed.
If you have a helmet that doesn’t have a CEP installed, you can order the communication
earplug kit with NSN 5965-01-474-5654.
EMI Filter for IMG MRAP Fire Suppression System Prevents Accidental Discharge
TACOM MAM 08-012 told you that users of International Military and Government (IMG-
MaxxPro) Mine Resistant Ambush Protected vehicles (MRAP), NSN 2355-01-553-4634, were
having accidental discharges of the cabin ±re suppression system (FSS) bottles. Some of the
vehicles arrived in Theater with the cabin FSS bottles already discharged.
Now we know the cause of this problem is electromagnetic interference (EMI). And you can
solve this problem by using an EMI ±lter. The IMG FSS vendor, Lehavot, will provide free EMI
±lters for retro±t on vehicles in Theater beginning in mid-April 2008.
IMG ±eld service reps will get them to you, and your unit mechanic can install them.

Out with the Old BB-390B/U,
In with the New BB-2590/U
There are two rechargeable batteries that can be
used in your BA-5590 powered equipment like the
ASIP SINCGARS. One is the BB-390B/U, NSN 6140-01-
490-4317. The other is the BB-2590/U, NSN 6140-01-
490-4316. Order the BB-2590 and not the BB-390.
Why? They’re close in cost and the BB-2590/U is more
powerful and lighter. But more important for the next
few months, the BB-390 is out-of-stock while the BB-
2590/U is ready to ship today!
