Vibration can pop open
the two latches on the fan
box. The door falls open and
gets crunched big time when
the turret is traversed. Even
worse, the door can take a
lot of electrical cables and
connectors along with it, too.
You can put a stop to that
damage by safety-wiring the
latches after closing the door.
The safety wire keeps the
latches fastened and the
door closed.
W
hen you’re approaching a sharp turn overlooking a long drop, it’s a little late to
wonder if you’ve lubed your M113A3’s steering control bearings.
Without regular lube, the steering gets stiff and harder to turn. And since the
carrier’s a little too heavy to fly, that’s not a good thing.
There are three lube points for the steering control bearings. Most crewmen
remember the two on the steering shaft. But the third one, which is located in the
engine compartment, is often missed.
Lube all three Fttings
with GAA semiannually
or every 1,500 miles,
whichever comes Frst.
That’ll keep the steering
linkage moving and you
on the road.
It’s also a good idea
to check the Fttings after
washing or fording the
vehicle. If they’re wet,
give the steering control
bearings another lubing.

that’s the sound of the
fan box in your bradley’s
turret wall coming open
during operation, crewmen.
the sound’s not pleasant,
and it can lead to even
more unpleasant—and
expensive—repairs.

oh, no!
there goes
my fan box

Without lube, steering linkage can stiffen
I’d sure feel
a lot better
about this if
they had lubed
my steering
