M915A4 Tractor Truck…
Dear Editor,
Our unit found out the spare fuse receptacles on the tractor truck’s fuse
panel aren’t slots for spare fuses! For instance, Spare 4 is a fuse for the
wiper/washer.
Just thought you could pass this onto other operators and mechanics.

Dear SPC Dickinson,
Thanks for the heads-up.
Matter of fact, here’s the other fuses
(shown as spares) and what they’re for:
Spare 1
Spare
Spare 2
Trailer ABS (along with fuse next
to it)
Spare 3
Diagnostics ignition power
Spare 4
Wipers/washer
Spare 5
12-volt dash power receptacle
Spare 6
Mirror heat (along with fuse next
to it)
Make a note of these fuses until
there’s a change or revision to
TM 9-2320-303-10.

HEMTT…
with my
new
guard,
I don’t have
to worry about a
cracked fuel-water
separator bowl!
that’s
not
a
spare,
either!
hmmm,
ok. what
about this
one?
HEMTT Static Reel
NSN
5340-01-269-4423 gets the static reel for the M978 HEMTT fuel tanker.
This NSN replaces the parts info shown as Item 1, Fig 282 of TM 9-2320-279-24P.
t
he fuel-water separator on your
HEMTT won’t do its job if its plastic
bowl is cracked or broken.
Protect the bowl by installing a fuel
bowl shield, NSN 2540-01-383-2252,
using three cap screws, NSN 5305-00-
269-3211, three nuts, NSN 5310-00-
655-9544, and three lock washers, NSN
5310-00-637-9541. The shield will
keep rocks, gear, big feet and other
items from cracking the bowl.
See Page 4-41 of TM 9-2320-279-20-1 for instructions on installing a replace-
ment shield. If your truck has never had a shield installed, you’ll need to drill some
mounting holes first.
Use the shield as a template to mark the hole locations. Place the front of the
shield 2
1
⁄
2
inches from the back of the tire carrier and 3 inches in from the edge of
the fender.
