A Key Preventive Measure
Dear Half-Mast,
We have to be “NASCAR quick” out there to change tires on our M1114s.
That’s why I’m searching for a good portable impact wrench, but I haven’t
found one yet. Can you help?
1LT L.A.
Dear Lieutenant L.A.,
Either NSN 5130-01-536-6492 or
NSN 5130-01-363-0964 will get you a
good portable, electric impact wrench.
But you’ll need to buy a
7
/
8
-in socket to
remove the lug nuts since the socket you
need isn’t provided. Use NSN 5130-01-
400-0177 to get the socket.
The additional authorization list (AAL)
in TM 9-2320-387-10 will be updated to
reflect these NSNs.
•
Inspect fasteners for breaks, stretching, looseness, cocked heads, or hole lengthening.
•
Inspect seams, flanges and joints for straightness or local deformation as an indication
that fasteners may have been stretched or holes lengthened.
•
Thoroughly inspect adjacent areas for damage, distortion or misalignment.
•
Inspect the up-armored HMMWV roof and support pillars for potential fatigue.

NSN 5130-01-363-0964 brings a good
portable, electric impact wrench
if your hmmwv has field mods that
have
been approved,
increase
pmcs.
when it comes to added roof weight
on up-armored hmmwvs with gpk or
o-gpk, at least do the following…
report all
deficiencies
to field
maintenance.
they’ll
get you
squared
away.
let’s
move it!
I think this
portable impact

come in handy!
