ometimes quick-release pins are a
little too “quick” for their own good.
That’s especially true of the steering
and brake linkage quick-release pins
in your tank.
Dirt and corrosion jam
each pin’s retaining mecha-
nism. When that happens, the
pin won’t lock in place. So,
after you install it, the pin
may not stay put. That means
you can lose your steering or
brakes, depending on which
pins fall out.
When you check the quick-
release pins as part of your before-
operation PMCS, make sure the
spring-loaded balls are holding each
pin firmly in place.
radley crewmen, the forward crew
compartment bottle and valve assem-
bly, NSN 4210-01-107-3329, on the
fire suppression system uses one of
three different valves. Two of them can
cause safety problems:
•
Valve, part number (PN) 12308781-
1, has problems with internal corro-
sion that could prevent it from
working.
•
Valve, PN 12308781-2, has a prob-
lem with the cable pull support bracket.
When this valve is located in the for-
ward crew compartment, the support
bracket interferes with the operation
of the cable for the manual release le-
ver. When you need to activate the fire
extinguisher, it may not work.
If the valve, PN 12308781-2, is used
in the forward crew compartment of
the
basic
M2/M3 Bradley, don’t worry.
There is no cable problem for these
two vehicles.
M1-Series Tanks . . .
M2/M3-Series Bradleys . . .
The parking brake pins, NSN 5315-
00-008-5826, and the service brake
pins, NSN 5315-00-904-6182, need to
be checked, too.
Check quick-release pins for looseness
Just give the pin a pull. If it comes
out too easily, clean it or replace it
with a new pin. The steering pin, NSN
5315-00-904-4788, slips out most of-
ten, so check it closely.
Valve, PN 12308781-3, is the
only
one that
can be safely used in the forward crew compart-
ment of
all
Bradleys.
If your vehicle has valve, PN 12308781-1 or
12308781-2, turn in the entire bottle and valve
assembly for Halon reclamation and order a new
bottle and valve assembly on a DD Form 1348-
6. In the REMARKS block, specify that the
assembly must include valve, PN 12308781-3.
Otherwise, you could receive one of the two
valves with safety problems.
Look for part
number on valve’s
data plate
he said
the
steering
went
out
on him!
i'd guess one
of the steering
linkage quick release
pins is
missing
!
i don't
get it!
i tried to
activate
the fire
suppression system,
but nothing
happened!
