Max Speeds for M939s
It’s official, drivers. Change 1 to TM 9-
2320-272-10 sets maximum safe operating
speeds for M939/A1/A2-series 5-ton
trucks:
Highway and secondary roads

Cross country roads
35 mph
Sand and snow
25 mph
Icy conditions

PLS Tail Lights
Need 12-volt light bulbs for the PLS’s
composite tail light? Don’t use the ones
shown as Items 7 and 8 in Fig 98 of
TM 9-2320-364-24P—they’re the wrong
bulbs. Instead, use NSN 6240-00-143-3159
for Item 7 and NSN 6240-00-617-0991 for
Item 8.
M870A1 Hub Cover
NSN 5340-01-042-0573 gets the axle hub
cover for the M870A1 40-ton semitrailer.
The cover’s vent plug also comes with
this NSN even though it’s not shown with
Item 2 of Fig 20 in TM 5-2330-378-14&P.
M35A3 Beadlock
Need only the beadlock for a wheel on
the M35A3 2
1
/
2
-ton truck? Make a note in
Fig 117 of TM 9-2320-386-24P that Item 2
is NSN 2530-01-398-2022. You don’t have
to order the entire wheel to get the
beadlock.
Elastic Cord for Covers
If your truck’s cargo and cab covers are
secured by black elastic (“bungee”) cord,
you can make your own replacements.
Get 280 feet of bulk cord with NSN 4020-
01-463-8181.
HMMWV Wheel Kit
NSN 2530-01-443-3405 is the new kit NSN
that gets Items 17-19 and 22-29 in Fig 139
of TM 9-2320-280-24P-1. The current NSN
is wrong. Items 20 (runflat device for either
a bias or radial tire) and 21 (lubricant for
either a bias or radial tire) are not included
in the kit. For a complete tire and wheel,
see Fig 140.
6K VRRT Forklift Clip
The internal retainer clip for the spotlight
assembly on the variable reach rough
terrain forklift is now available separately.
Order it with NSN 5340-00-693-4175 and
make a note until the NSN is added to Fig
61 of TM 10-3930-660-24P.
HMMWV Oil Pan Installation
Replacing a HMMWV oil pan is tough
enough with all the parts you need on-
hand. But Fig 4 of TM 9-2320-280-24P-1
makes no reference to nut, NSN 5310-01-
158-6257, and two washers, NSN 5310-00-
582-5965 (box of 100), needed to mount
the starter cable support bracket. The nut
and washers are found in Fig 66 as Items
34 and 35.
HMMWV Transmission Filter
NSN 4330-01-438-3813 gets a transmission
filter kit for M998A2-series, M1113
enhanced capacity vehicles (ECV) and
M1114 up-armor HMMWVs. The kit
includes a seal and filter. It doesn’t include
the reusable transmission oil pan gasket,
NSN 5330-01-360-5271. The kit includes
Items 35 and 36 in Fig 94 of TM 9-2320-
280-24P or Items 12 and 13 in Fig 88, TM
9-2320-387-24P.
HMMWV Brush Guard Kits
M998A2-series HMMWVs have their own
brush guard kits, NSN 2510-01-461-7075.
The kit shown in Fig 400 of TM 9-2320-
280-24P-2, NSN 2590-01-328-2904, is only
for basic and M998A1-series HMMWVs.
Make a note until the TM catches up with
this information.

M1022A1 Dolly Set Seal
NSN 5330-01-464-9956 gets a seal for the
wheel assembly on the M1022A1 dolly set.
The entry for Item 13 in Fig 17 of TM 9-
2330-390-14&P is wrong. The item is not a
spacer.
