Braking
Dear Sergeant Blade,
As armorers, our Kiowa Warrior’s M296 .50-cal machine gun has had
some feeding and jamming problems since the installation of the new gun
jettison rack, NSN 1095-14-553-8310.
Because the gun sits lower with the new jettison rack, the ammo chute
is too short, causing feeding problems for the rounds. The chute is not as
flexible and a little too short with the new rack.
We’ve come up with a simple solution to stop gun jams. We added two
extra links, NSN 1010-01-368-0242, to the end of the chute to get the
rounds to feed properly into the gun.
Since we’ve added the links, the gun operates without any problems.

Shifting
Dear Specialist J.S.,
Good job! Looks
like you found the
missing links to
solve this problem.
OH-58D…
Got Gun Problems?
Add two
links to
ammo
chute to
prevent
jams
if you have
conventional
hydraulic
brakes,
pumping ‘em is
permitted.
but if your
vehicle has
anti-lock
brakes (abs),
do not
pump them.
apply
firm, even
pressure
instead.
and if you have
air brakes, apply
light, steady
pressure.
don’t
pump ‘em,
either.
if your vehicle
has a jacobs
brake (known as
a jake brake),
don’t use it
in slippery
conditions.
in icy conditions,
it takes more
distance—up
to 12 times as
far—to stop.
and
never
slam on the
brakes!
front wheels
lock with heavy
braking and you
lose steering.
so don’t
slip up on
your winter
driving!
the engine holding back your wheels
is applying force to them just as
the brakes would do. it can throw
you into a skid. so if you feel your
vehicle start to slide, speed up until
your wheels are no longer sliding.
use care when shifting during
winter driving, especially while
downshifting. downshifts can
break traction, so make each
shift as smooth as possible.
with a manual transmission,
you could get over the top
of the grade using one or
two gears higher than you’d
use under ideal conditions.
on a dry road, you
might want to shift
down to a lower gear
to use the engine as a
brake. on ice, that can
cause problems.
so make sure
you allow
plenty of
room to
stop.
This new jettison rack
is giving me no end of
grief! I’ve got chronic
feeding and jamming
problems!!
I have
the
solution
right
here!
adding
These two
links will
fix you up.
the results
could be
chilling!
