Avenger Missile System…
TW-25B, NSN 9150-01-439-0859, is the
only lube to use on the gun. CLP is not strong
enough to stand up to the heat the M3P pro-
duces during firing. (The elastic cradle,
though, is lubed with LSA, not TW-25B.)

A
cid spills from batteries causes corro-
sion on the bottom of battery boxes.
But that acid doesn’t have to get a free
shot. Use NSN 6160-01-389-1966 to
get a roll of battery box liner for tacti-
cal, CCE/MHE and combat equipment.
The liner works like a sponge that
absorbs and neutralizes battery acid.
Cut the 1/4-inch thick liner to fit the
bottom of your vehicle’s battery box.
M1070 HET O-Ring
NSN 5331-01-357-0846 gets an O-ring for the counterbalance
valve in the heavy equipment transporter’s auxiliary winch. The O-
ring is missing from the valve body that’s shown as Item 18, Fig
221 of TM 9-2320-360-24P.
HET Battery Disconnect Kit
Batteries are known to run down on the M1070 heavy equipment
transporter (HET). You mechanics can put an end to dead batteries
with a battery disconnect kit that comes with NSN 5930-01-494-
9353. Installation instructions come with the kit.
BII 12-Volt Cable Assembly
NSN 6150-01-478-6510 gets the 12-volt cable assembly for the
M915A2 and M916A1/A2 tractor trucks. This NSN replaces the
parts info shown as Item 6, Page B-4 of TM 9-2320-363-10.

The two most common
mistakes when it comes to
cleaning and lubing the
M3P are using the wrong
lubricant and putting on
the wrong amount.
If the M3P is just going
to sit in the arms room,
give all parts a heavy
lube. It's a different story
for firing, though. Parts
take different amounts of
lube then. See the chart
on the next page for what
parts get what lube.

is all I need.

tomorrow.

parts need a
light coat!

what
about
me!?
U
nfortunately, too many Avenger units do
forget
the M3P machine gun when it
comes time for PMCS. The M3Ps are stored down in the arms room, not at the motor
pool, and no one bothers to go get them. The Avenger gets a thorough PMCS, while
the M3P is ignored.
..until it's time to fire it. Then it's discovered the gun has corro-
sion or its lube has dried up and caked and gummed up moving parts.
Don't expect the armorer to be taking care of your unit's M3Ps. Usually, that's the
Avenger crews' jobs. At least monthly, get your M3Ps out of the arms room and give
them a good PMCS. Look for corrosion and signs the lube is drying up. Clean and
lube the gun if necessary.
