f you haven’t kept up with the changes to TM 9-2330-381-24P for your M1000,
you may hear a loud CRUNCH! when you lower your semitrailer.
The original Anchorlok brake chamber, NSN 2530-01-329-2187, used in the
M1000 is too big. It can hit the underside of the platform if the semitrailer is fully
lowered. The brake chamber can even be dislodged, resulting in air loss great
enough to lock up
all
the brakes on the semitrailer.
That leads to significant tire damage and, depending on road conditions, could
result in your losing control of the vehicle.
To prevent this, a new Meritor brake
chamber, NSN 2530-01-387-8426,
was listed in Change 2 to the -24P TM.
Unfortunately, some units without this
change are continuing to order the old
Anchorlok brake chamber.
So, right now, go check the brake
chambers on your M1000. If you find
any with Anchorlok printed on the top
of the chamber, notify TACOM. You
may even be eligible for a free-issue
replacement of the brake chambers.
Check out TACOM Ground Precautionary Message 03-006 for more details.

M1000 HET Semitrailer…
Round off the edges and paint the board to prevent splinters. Stencil NO STEP on
each side of the board.
To use the shield, remove the
eyehook seals and slip the shield
over the two lifting rings, laying
it flat on the oil cooler frame.
The rings will hold the shield in
place.
Never use the shield while the
engine is running because it
stops air flow and causes engine
overheating.
Be sure to replace the eye-
hook seals after using the shield.

Get the heater blower motor for the
HMMWV with NSN 6105-01-463-
5260. This NSN replaces the one
shown as Item 13, Fig 333, of TM 9-
2320-280-24P-2.
NSN 4720-00-065-8682 gets the bulk
rubber hose for the HMMWV wind-
shield’s washer bottle. The parts info
shown in Fig 327 in TM 9-2320-280-
24P-1 is wrong.
The dimen-
sions are
approximate,
so you may
need to
adjust them
to
your
HMMWV.
