very time you disconnect an FMTV’s driveshaft—like when you service its
transmission oil filters—you must replace the yoke end cap bolts.
They cannot be re-used because they will not hold tight. The yoke cap will
come off and the U-joint could
come apart.
To get the bolts, use NSN 5305-
01-472-3766. The NSN is not found
in either FMTV TM. If you have
any 2

-ton models, make a note
for Items 4 and 7 in Fig 128 of TM
9-2320-365-24P. If you have any
5-ton models, make a note for Item
4 in Fig 153 and Items 4 and 11 in
Fig 154 of TM 9-2320-366-24P-1.
Also make a note in your maintenance TMs that the bolts must be replaced
with new ones every time the yoke is disconnected.
for you HMMWV owners who need repair informa-
tion for the side channels that attach to the
radiator core.
The info is available on Pages 9-18 through
9-24 in TB 43-0001-62-3 (Oct 99). Without
the info, you’ll replace a lot of radiators that
could be repaired at unit level and put back
to work.
Materials and procedures are listed in
the TB, also known as the
EIR Digest for
Tank-automotive, Armament and Chemical
Equipment
.
Don’t have a copy of the TB? See your
local TACOM logistics assistance representa-
tive. No luck there? Let Half-Mast know and
he’ll send you a copy of the facts.

tronics Product Support web site at:

End Control Arm Confusion
O
wners of M998A2-series HMMWVs and those with M1113 and M1114
models, take note:
Your parts manuals provide wrong information about which lower control arm
is used where on the trucks. Here’s the straight info, which you should note until
the TMs are updated:

, for M998A2-series models, Fig
121, Item 20—Part number (PN) RCSK-17250 is the left-hand
(LH) front lower control arm. PN RCSK-17249 is the right-hand
(RH) front lower control arm.
Fig 127, Item 20—PN RCSK-17249 is the LH rear lower control
arm. PN RCSK-17250 is the RH rear lower control arm.
TM 9-2320-387-24P (Sep 98)
, for M1113 and M1114 models,
Fig 120, Item 19—PN RCSK-17249 is the LH rear lower control
arm. PN RCSK-17250 is the RH rear lower control arm.
