M2/M3-Series Bradleys…
C
rewmen, don’t underestimate the importance of the skirt bracket bolts, NSN
5305-00-724-7222, on your Bradley.
Those skirts are
very
heavy. So if even
one of the bolts vibrates loose, a lot of
pressure is put on the remaining ones.
They can snap and leave you with no
bolts and a missing skirt.
Eyeball the skirt bracket bolts before
and after every operation. If any are loose
or missing, tell your mechanic. He’ll
replace and torque ‘em to 151-166 lb-ft.
Mechanics, despite the crew’s best efforts, sometimes those bolts are going
to snap. That leaves you with the miserable job of drilling them out so they can
be replaced.
Tankers, unless
you’re on a fire
mission,
make
sure
you lock the
turret and main
gun first
before
moving out.
All the bouncing and vibration can damage the
traversing mechanism and the elevation mechanism if
they aren’t locked down for travel. That’ll be a
real load on your unit’s maintenance budget.
Engage main gun
travel lock…
…and turret lock before
moving tank
Loose skirt bolts can snap off
ouch!
that’s
gonna
hurt!
That job just got a whole lot easier
with the addition of a special tool kit
for removing broken bolts.
The kit, NSN 5180-01-518-6883, is
designed to remove 1/2- to 3/4-in
bolts without damaging the existing
threads. Detailed instructions come
with the kit.
