M939A2-Series Trucks…
A
clogged sink in your bathroom is a real hassle. Sometimes you have to call in
a plumber to get rid of the clog.
A clogged fuel filter on your M939A2-series 5-ton truck is a real hassle, too.
That small in-line fuel filter can clog up fast . . . stopping you in your tracks.
Order a bigger and better in-
line fuel filter kit with NSN
You won’t need a plumber
to have this kit installed. But
you will need a buddy in direct
support to make the initial
changeover on the vehicle.
Instructions come with the kit.
HMMWV Seatbelt Assembly
Use NSN 2540-01-495-0817 to get an improved seatbelt assembly for the HMMWV. The
assembly has a longer strap (about 8 inches) made of a slick material which provides a
smoother retraction.

M929/A1/A2 Dump Bed…
S
tanding water in the dump truck’s bed is the tell-tale sign of clogged drain holes.
And water that sits long enough in the dump bed causes it to rust out—not good!
So eyeball the drain holes in the front corners of the bed for dirt and leaves. Watch
for holes that are painted over. Then, remove any debris or paint by running the tip
of a ballpoint pen or small screwdriver through the holes to open ‘em up.
Another way to keep water and snow out of the dump bed, especially when your
5-tonner sits for long periods of time, is to keep the bed elevated. Use the dump
body support braces (bedlocks) to hold the bed up and keep pressure off the dump
body’s main hydraulic cylinder.
Page 2-19 of TM 9-2320-272-10 tells how to use the dump body’s bedlocks.
