T
he 1W300 cable, NSN 6150-01-426-2197, for the driver’s night viewer, may have
a few droops and dangles. That puts it in harm’s way when you close the driver’s
hatch. A crushed cable can cause a Fre if it shorts out.
The cable has been redesigned to add an in-line fuse to help with the Fre threat, but
it’s up to you mechanics to keep the cable safe from the hatch. That means rerouting
the cable on the hatch to stop the dangling. Here’s how:
2.
route the cable along
the driver’s hatch, keeping
the first two loop clamps
parallel with the bottom of
the hatch.
W
hen climbing on top of your Bradley, you’re
looking for a step up wherever you can Fnd it.
At Frst glance, the driver’s vision enhancer (DVE)
looks like just what you need. It’s handy for getting on
top of the turret and it’s armored. No problem, right?
Wrong!
The DVE is
not
a step. Sure, it’s armored, but
enough jolts and blows from those size 12 boots can
still mess up the camera. So Fnd another way up top
and keep your feet off the DVE.
3.
continue routing
the cable along
the periscopes
using loop clamps
and the periscopes’
mounting screws.
4.
at the coiled end, disconnect
the cable clamp from the hatch.
re-position the clamp about 1 inch
up from the coiled section of the
cable and reattach it using the
old hardware in this sequence:
•
Loop clamp, NSN 5340-00-954-6014,
holding the 1W300 cable
•
Sleeve spacer, NSN 5365-01-172-7899
•
Flat washer, NSN 5310-00-080-6004
•
Eye bracket, NSN 3040-01-106-7812
•
Flat washer, NSN 5310-00-080-6004
•
Self-locking bolt, NSN 5306-01-110-7884
1.
make sure the cable is
routed out of the bradley
between the two sections of
the hatch opening cushion-
ing pads located over the
driver’s left shoulder.
