HMMWV Hot Starts
If you have a HMMWV that will not restart
after the engine gets hot, eyeball the serial
number of the fuel injection pump. Some
pre-1994 GM 6.2L and 6.5L fuel injection
pumps have had hot engine restart
problems. Pumps with serial numbers
under the break number shown below
should be replaced by your support unit.
Report all such pumps to support so they
can replace them with a new fuel injection
pump that has an improved hydraulic head
and rotor assembly.
HMMWV Seatbelt MWO
The only way you can get 3-point seatbelts
installed correctly in your HMMWV is by
having your support apply MWO 9-2320-
280-35-2.
You
cannot order all the parts
needed from the supply system. Only your
installation MWO coordinator can do that.
If you have installed your own 3-point
seatbelts, your vehicle is unsafe. Remove
the belts and contact your MWO
coordinator to have the seatbelts installed
correctly. See TACOM Maintenance
Advisory Message (MAM) 99-004 for the
details. Note that the correct kit NSN for
the front seats of non-armored HMMWVs
is 2540-01-387-
4018
, not NSN 2540-01-387-
5682.
SEE Hydraulic Filter
NSN 4330-01-273-2833 gets the small
emplacement excavator’s hydraulic filter
that’s shown as Item 20 in Fig 317 of TM 5-
2420-224-24P. The NSN shown in the TM
gets the wrong filter.
MLRS Charging
Page 39 in PS 570 (May 00) steered you
wrong on charging the MLRS launcher/
loader module (LLM) batteries. To charge
the batteries, run the engine at 1,200 to
1,400 rpm with the interconnect switch—
not the fire control panel—on.
DoD Web Site for MSDS
Army users can now view and print Materiel
Safety Data Sheets (MSDS) on the Internet.
The same info available on the quarterly
Hazardous Materials Information System
CD-ROMs is now available by clicking on:
POL User’s Guide

of Army petroleum, oils and lubricants

the hazardous or toxic components of POL
and hotline numbers for info on state and

Right Chains for M35A3 Tires
The tire chains in TM 9-2320-386-10’s
additional authorization list (AAL), NSN
2540-00-933-9022, will not fit the M35A3
2
1
/2-ton truck. The right chains are PN
S05SV, CAGE 4N506, available only from
the vendor, PEWAG Austria Gmbh. In
Europe, call 43 316 6070, Ext 246, fax 43
316 6070 100, or e-mail:
Koe@pewag.com
In CONUS, call (800) 526-3924 or (630) 323-
4342, fax (630) 323-2292 or e-mail:
peterb@pewagchain.com
Also, you need one pair only, for the
intermediate axle. The AAL is wrong in
requiring three pairs. The TM is scheduled
to be changed.
M1052A2 Chain Assembly
NSN 4010-01-447-0753 gets a chain
assembly with hook for the 1
1
/2-ton trailer.
This assembly replaces Items 5, 6 and 7 in
Fig 24 of TM 9-2330-213-14&P.
drat!
