HEMTT LHS Switch Knob
Your HEMTT’s load handling system rotary switch knob is shown as Item 13 in Fig 2001
of EM 0232, TM 9-2320-315-14&P. But the NSN listed is obsolete now because the knob is
no longer available by itself. Get a replacement switch assembly, which includes a new
knob, using NSN 5930-01-372-9489 and part number 3533104.
HMMWV V-Belt
Inversion Works
Having problems with the adjustable link
V-belt used on your HMMWV’s serpentine
belt system and found in your BDAR kit?
You know, it’s the V-belt that has a tendency
to walk off the pulleys.
You can Fx this by inverting the V-belt,
a solution approved through the SMART
suggestion program. Putting the flat side
against the serpentine pulleys is the trick.
Testing shows this allows the V-belt to
perform better and it’s less likely to wander
off the pulleys.
DEXRON VI OK
for HMMWV
All HMMWV transmissions and power
steering systems are compatible with
DEXRON VI fluids. And you don’t have
to flush your transmission or steering
system before adding DEXRON VI to
it. That’s because testing proved that
mixing DEXRON III and DEXRON VI won’t
degrade the transmission or steering
system performance.
Keep this info handy until HMMWV
technical manuals and lubrication orders
are updated.
Tank and Pump Unit Hoses
Use NSN 4720-01-022-6016 to get the hose that
connects the forward tank to the manifold on
the mil design tank and pump unit. This NSN
replaces the one shown as Item 1 in ±ig 14 of TM
10-4930-236-13&P. NSN 4720-01-360-4360 gets
the hose shown as Item 3 in the same Fgure.
Check FMTV Annual Service Kits for Faulty Axle Seal
A faulty axle seal, NSN 5330-01-360-5252, has been mistakenly included in some ±MTV annual
01-533-6745, NSN 2590-01-528-7508, and NSN 2590-01-528-7243.
The seal, made by YEI, has an inside diameter that’s too small. If you Fnd any of these seals
in these kits, don’t try to use them. Use all the other kit components and submit a PQDR for
the kit. Request credit for the seals; D±AS will allow it. Then order just the correct Meritor seals
from DLA using NSN 5330-01-360-5252.
Turn the wrong seals in to DRMO or destroy them using local SOP.
M915A3 Sending Unit
Use NSN 6685-01-081-9721 to get the sending

line that’s shown in Item 9, ±ig 93 of TM 9-
2320-302-24P.
V-Belt for M35A3

truck’s V-belt shown as Item 8 in Fig 49 of
TM 9-2320-386-24P. The NSN shown in the
TM for the V-belt is wrong.

Use NSN 6130-01-521-138
7
to get a new solar charger/AC charger (w/o case, with solar panel)
for your M777-series towed howitzer. NSN 6130-01-521-138
6
, which is listed as Item 76 on Page

549-5835 (p/n 11790).
Use Project Code 924
for MRAP Parts!
MRAP users, whenever you order parts to
support your MRAP vehicle, use project code 924,
not
9GJ, the code for OEF, OIF, and HOA. Code 924
also gives priority air transport for MRAP parts.
