SECM Compressor
NSN Change
If you have SECM (shop equipment contact
maintenance), NSN 4940-01-333-8471, the
NSN for its three-phase air compressor
has
changed
from
(PN
11B297018)
to
(PN 11B297018). If you have SECM, NSN
4940-01-333-8470, with the single-phase
air compressor, continue to order the
compressor with NSN 4310-01-432-9655 (PN
11B257019). Questions? Contact TACOM’s

Address Change for
Mortar Help Desk
The TMs for the M95/M96 mortar Fre control
system (M±CS), and M32 lightweight handheld
mortar ballistic computer (LHMBC) give an
assistance email address in their “Reporting
Software and Hardware” sections. That address
has changed to:
pica.mfchelp@conus.army.mil
Only hardware and software questions about
these three systems should be sent there. Send all
other mortar questions to:
ROCK-TACOM-MORTAR-SYSTEMS@
conus.army.mil
or call DSN 793-1279/(309) 782-1279. Copy these
changes into your TMs.
Up-Armored HMMWV
A/C Compressor
Need the NSN for your M1151, M1152, and
M1165 up-armored HMMWV’s air conditioner
compressor shown as Item 3 in Fig 276G of TM
9-2320-387-24P? Place your order using NSN
4130-01-539-6297. And make a note until the
TM is updated.
M1-Series Tank Gun Tube
Got an M256 gun tube on your M1-series tank that’s deemed unserviceable because of
pitting, erosion or round count? Here’s what to do.
Regular Army units should ±ll out a DA
Form 2765-1 and submit it to your Supply Support Activity (SSA). Army National Guard Units
should turn the form in to their United States Property Fiscal Of±ce (USFPO). Then, don’t
forget to update the electronic DA Form 2408-4 with re-tube information:
While you’re there, make sure you annotate that the old tube was sent to DRMO for demil.
M1A1 RTNB
Subassembly
Mechanics, if you’re trying to order the
subassembly (Item 16A in ±ig 140 of
TM 9-2350-264-24P-2) for the M1A1’s
redesigned turret networks box (RTNB),
stop! Although it appears you can order
it with NSN 6625-01-547-4335, the
subassembly was never stocked. The
correct SMR code for the subassembly is
XAO±±, which means you should order
the next higher assembly. That’s the
complete RTNB in shipping and storage
container, NSN 5975-01-537-3765, shown
as Item 15 in ±ig 140. Make a note until
the TM can be updated.
Tail Wheel Lock
Actuator Pin
We told you on page 35
of PS 665 (Apr 07) that
if the quick release pin
is not in place before
towing your AH-64, the
tail wheel lock actuator
will shear. That’s not
quite correct. It is the
tail wheel lock pin that
will shear. Make sure
the quick-release pin is
in place.
Explosion-Proof Flashlights
Working in an area where there’s risk of
explosion from flammable vapors, POL,
ammunition,
explosives
or
combustible
dusts? Need a light that’s safe to use in these
areas?
GSA has explosion-proof flashlights that
are up to the task. NSN 6230-00–299-3035
brings an 8
1
/
4
-in hard plastic flashlight. NSN
6230-01-413-8296 brings a head lamp with an
adjustable hard hat headband.
To order or for more information, go to
the GSA Advantage website:
Maintenance on the MCU
On Pages 35-37 in PS 651 (±eb 07), we gave you the
Dos
and
Don’ts
of the microclimate cooling
system (MCU). ±or those authorized to do maintenance on the MCU, you can now order
propylene glycol in one gallon containers with NSN 6810-01-181-7121.
Vacuum Sealer and Bags
ALSE techs, there are some items that
need to be protected in a heat-sealed
vacuum-packed bag. If you need a
vacuum sealer, order it with NSN 3450-
01-386-2478.
NSN
brings an 8 x 240-in roll of bag material
and NSN 8105-01-381-6374 brings an 11 x
240-in roll of bag material.
clean up with hand sanitizer
Purell hand sanitizer can be locally purchased using NSN
6508-01-535-5409. This NSN brings twenty-four 3 fl oz bottles
in foliage green. The containers are built to withstand heat
and can be opened with one hand. The sanitizer kills 99.99
percent of most common germs.
Stryker Tow Bar Revisited
On Page 2 of PS 664 (Mar 08), we told you to use NSN 2540-01-
517-9227 to get a two-piece tow bar wide enough to use with slat
armor-equipped Strykers. Turns out that tow bar is a non-stocked
TACOM item and all requisitions are being rejected. Single Stock
±und requests also cannot be supported, but those requisitions must
be cancelled by the customer.
Each brigade receives a number of tow bars at Initial ±ielding.
You can get extras only by submitting a Military Interdepartmental
Purchase Request (MIPR) through PM Stryker BCT. The POC is Tim
Evers, DSN 786-2103, (586) 753-2103, or email:
timothy.evers
@us.army.mil
The Stryker tow bar will eventually be transferred to DLA for
management, at which time it will be available through the supply
system. Stay tuned to PS for word on when the transfer is ofFcial.
