echanics, the screw that holds the protective guard on the Bradley’s hatch
interlock override switch, NSN 5930-01-115-7334, is often missing in action.
Vibration loosens the screw, making
it fall out or snap off. Then the guard
falls off.
The TM says to replace the entire
switch at a cost of more than $100.
The headshed says you can save your
unit some dough by replacing the screw
instead. NSN 5305-00-995-3440 gets
100 screws for less than $3.50.
Cycling to Good Repair
Dear Editor,
M242 automatic gun feeders are being returned from repair with one
important check not being done: the feeder manual cycle check. If a feeder
can’t cycle rounds, it won’t be feeding and the M242 won’t be shooting.
Support and unit repairmen should always finish any repair on the
feeder by doing the feeder manual cycle check that begins on Page 2-28
in TM 9-1005-200-20&P. Cycle a dummy round, NSN 1305-01-105-4095,
through the feeder in both the HE and AP modes. Only then is a feeder
ready for duty again.

i'm happy
with
steel
and
aluminum
wheels.
it's
aluminum
or
bust
for
me!
ith two types of roadwheels
available for your Bradley and
MLRS carriers, the question is
whether you can mix steel wheels
with aluminum ones.
The answer is ye
s...
and no.
The steel roadwheel, NSN 2530-
01-310-2237, and the aluminum
roadwheel, NSN 2530-00-801-
6702, are interchangeable on any
Bradley model as long as you fol-
low this rule:
The two roadwheels used on
each individual road arm
must
be
made of the same material. In other
words, never pair a steel wheel with
an aluminum wheel on the same
road arm. If you do, you’ll get un-
even wear and early failure.
Unlike the Bradley, MLRS carriers are
restricted to
aluminum roadwheels only
in order to meet air transportation weight
restrictions.
It’s easy to tell the two roadwheels apart.
The aluminum wheels have a steel wear
plate riveted to them. Steel wheels have no
wear plate and no rivets.
THAT loose
screw IS GOING TO
COST SOMEONE
$100.
see ya!
...while steel roadwheel has none
Aluminum roadwheel has rivets.
