Operators in a hurry will pull
the chocks from under the wheels
and toss ‘em anywhere on the
truck that seems handy. These
are the same operators who are
constantly ordering or fabricating
new chock blocks because theirs
got lost somewhere on the road.
When you pull those chock
blocks, follow the guidance in
your HEMTT operator’s manual
on where to stow ‘em. Non-
wrecker HEMTTs come with a
wheel chock stowage box for two
of the chock blocks.
M1070 HET Tachometer
Use NSN 2541-01-494-6557 to get a new tachometer replacement kit for the heavy
equipment transporter (HET) tractor. The new tachometer kit comes with a dash panel
assembly, generator signal, screw assembly, generator drive tang signal, protective
cap, tacograph wire set and installation instructions. The new kit replaces the old-style
tachometer shown as Item 1 in Fig 58 of TM 9-2320-360-24P (C2) (Feb 98). The new kit can
be found as Item 1 in Fig 246a of TM 9-2320-360-24P (31 May 09). If you already have the
new kit installed and need just the tachometer, use NSN 6680-01-503-6480.

you’re likely to
find your hemtt’s

you don’t store
them
right.

many fmtv
starters
biTe the
dust! but
why?
because
water
and
corrosion
seize up the engine’s starter as
a result of operating in water
deeper than 30 inches.
to stop starter damage, follow the caution
on page 0015-9 of tm 9-2320-366-10-2 and put
the flywheel housing’s vent plug in place when
fording the fmtv.
for regular driving
conditions, remove
the vent plug and
screw it back into
its storage port.
that way any
condensation that
builds up in the
flywheel housing
can drain out.
