Dear Half-Mast,
There are some places in the M2 machine gun's
TM 9-1005-213-10 and FM 23-65 that seem to contradict
each other. I was wondering if you could clear these areas up:
•
Para 2-3a in the FM says to use CLP to clean and
lubricate and Para 2-3f further says to use RBC only if
CLP isn't available. But Chapter 3 in the TM says to use
RBC and carbon removing compound for cleaning the M2.
So which is it?

Position and Azimuth Determining System…
W
hen components are breaking down on the position and azimuth determining sys-
tem (PADS), not enough units are sending them in for repair. As a result, the Army
can’t repair components and put them back in the field and units can’t get replace-
ment components to keep their PADS operating.
If you have
any
broken PADS components sitting in your unit, turn them in. The
following are in really short supply:
•
computer,
NSN 7020-01-120-4131, PN 880700-8 (Item 32 in Fig 1 of TM 5-6675-
308-24P)
•
power supply,
NSN 6130-01-117-7234, PN 880750-6 (Item 7 in Fig 30)
•
circuit card assembly,
NSN 5998-01-355-4518, PN 880598-1 (Item 9 in Fig 41)
•
computer subassembly,
NSN 7050-01-236-3232, PN 868199-1 (Item 8 in Fig 30)
•
circuit card assembly,
NSN 5998-01-182-5198, PN 880778-3 (Item 43 in Fig 30)
•
power supply,
NSN 6130-01-139-6339, PN 880600-3 (Item 33 in Fig 1)
•
circuit card assembly,
NSN 5998-01-315-1637, PN 880592-1 (Item 11 in Fig 44)
•
circuit card assembly,
NSN 5998-01-182-5202, PN 880690-4 (Item 21 in Fig 44)
•
control and display,
NSN 5999-01-117-1223, PN 880800-2 (Item 34 in Fig 1)
•
electronic component test set,
NSN 5999-01-117-7374, PN 877465-2 (Item 58 in

M2 Machine Guns…
For really
tough cleaning
jobs, RBC is
usually better
than CLP. Don't
mix CLP with
LSA or LAW.
They don't
work well
together.
it says here the army
doesn’t
have any
replacement parts
for you because no
one has been sending
parts in for repair.
drat!
now I’ll
never get back to
the field. I feel
so
useless.
good idea.
I’m
a little
confused,
too.
hmmm… this guy
is confused by
your Tm and Fm.
Send In Broken Components
CLP, RBC, and
carbon removing
compound are all
authorized for
cleaning the M2.
But RBC and
carbon cleaning
compounds are
cleaners only.
Above 10°, use CLP or
LSA. Between -10 and
10, you can use CLP,
LSA, or LAW. Below -10,
use
only
LAW.
let’s see if we
can straighten
everything out.
Thanks, sergeant, for
pointing out these
confusing areas in the
TM and FM. Hope this
clears everything up.
Once you're
finished cleaning
with them, you must
wipe the machine
gun dry and then
lube it with LSA or
LAW, depending on
the temperature.
CLP cleans and
lubes so no futher
lubing is required.
•
Item 4 in work package 0023 00-4 in the TM says
"Use LSA above 0° F and LAW below 0° F",
but 0023 00-6 says
"Between 10° F and -10°
F use CLP, LSA or LAW. Below
-10° F use only LAW."
What's correct?
