Assembly, Disassembly
Pull
the
lower
straight
drive shaft down only when
you’re installing or taking off
the feeder. And then put the
drive shaft back up ASAP.
If you leave the shaft down,
count on it being bent.
When
you
install
the
feeder,
make
sure
it’s
correctly
installed
on the receiver before
you push up the lower
straight drive shaft. If
the shaft doesn’t want
to go up, the feeder isn’t
positioned
right.
Re-
position it and try again.
Once the drive shaft handle is locked in place, the feeder handle should lock in
the down position easily. If it doesn’t, your repairman needs to check it out. If you
try to force the feeder handle down, you could damage the 14-pin connector.
If
you
set
the
gun
at
30
degrees, that makes it easier to
maneuver the feeder on and off.
When you remove the feeder,
make sure its handle is in the
down
position
before
you
lay the feeder on the ground.
That protects the feeder’s 14-
pin connector, which is easily
damaged.
Cleaning and Lubing
Solvent can make cleaning
off carbon easier, especially
on the bolt. But what you
don’t want to do is dunk
the bolt in a solvent tank.
The solvent ruins the bolt’s
track assembly gears, which
means a trip to support. If
you clean with solvent, use a
rag and brush.
But once you’re through
cleaning,
you must lube the
M242.
GMD is not pleasant
to work with, but your M242
will suffer corrosion if you
don’t
use
the
GMD.
The
barrel is especially prone to
rust and needs a light coat of
GMD inside the locking lugs
and barrel support bearings.
Use CLP on the rest of the
barrel.
Don’t get carried away lubing, though.
More
is
not
better.
Too
much
lube
attracts sand, which leads to jamming
and a very dirty weapon. A light coat of
GMD is all that’s needed on the outside
of the breech and locking lugs.
