Sure, you can slow the damage by occasionally wiping away any condensation
in the ammo compartment. But to really put the brakes to corrosion, you’ve got to
stop moisture.
A few bags of desiccant will do
the trick. Just open each ammo
door and put a bag or two on the
floor between the ammo tubes and
the compartment wall. NSN 6850-
00-264-6571 gets a drum of 300
bags of desiccant.
When it’s time to pull PMCS on
the hull ammo compartment, check
the desiccant bags. If they’re moist
to the touch or if the compartment
walls are wet again, it’s time for
new desiccant.
If the palm lever assembly (also known as the Cadillac) of the grip and gimbal
assembly of the old handstation is installed in the new handstation, the turret or gun
could move unexpectedly. That’s a danger to your crew.
If your Bradley has a handstation
with PN 12976221-21, make sure
the palm lever (Cadillac) doesn’t
stick when it’s depressed. This test
can be done with the turret power
on or off. But be careful doing it
with the power on because the turret
or gun could suddenly move. If
the palm lever is sticking, get
your repairman to replace it with
the
new
lever
assembly,
PN
12976320-1. Don’t use the hand-
station in the meantime.
There is no safety problem with
using the new grip and gimbal
assembly, PN 12976231-1, with
the old handstation as long as
the
new
lever
assembly,
PN
12976320-1, is installed.
