Never put the M242 in the solvent
washer or use CLP.
Solvent ruins the
M242's seals, O-rings, and bearings.
That means major repairs. For the same
reason, don't use CLP for cleaning and
lubing the M242. CLP breaks down
graphite grease in gears, sprockets, and
the track and bolt assembly, which
quickly wears out bushings, gears, and
bearings. It takes four hours for support
to tear down an M242 and regrease it.
Lube the M242 with GMD and general
purpose lubricating oil like TM 9-
2350-252-10-2 says.
Troubleshooting Help
If you have a misfire or jam, don't drop the vertical drive shaft. That throws off the
timing between the receiver and feeder. Don't turn off the relay assembly. That clears
out the logic from the turret distribution box and prevents firing. Your best bet is to
ask the master gunner for help.
If the reticle jumps around dur-
ing firing, you probably have a
loose resolver. Tell your repairman.
A loose resolver ruins accuracy. It's
a good idea to have the resolver
tightened before you go to the field.
If the M242 jerks from side to
side, the traverse drive assembly
probably needs to be adjusted. Tell
your repairman.
Advice for Repairmen
When you fill the recoil
mechanism with damper fluid,
put the mechanism in a vise like
TM 9-1005-200-23&P shows.
Some repairmen try to just lay
the mechanism on a table to do
the job and end up bending the
push rod. Then the whole recoil
mechanism must be replaced.
Remember to hook up the ammo chutes
whether you're going to fire or not.
If the
chutes are left dangling when you install the
M242, the chutes catch on cables when the gun
is raised or lowered. That damages the chute
locking levers and can rip out cables and wiring
and lock up the turret.
Damaged ammo chutes can be repaired with
fitting repair kit, NSN 2320-01-268-7915.
And you
know
how effective the
M242 is when it's
shooting right.
Hook up ammo chutes even
if you’re not going to fire
Never put M242 in solvent tank
Don’t drop drive shaft
if you have a misfire
Put recoil in vise to fill
with damper fluid
oh, no!
please don’t
put me in
solvent!!
