rivers, Para 2-5.5d of TM 9-2350-314-10 reminds you to check all attaching
hardware for looseness during your PMCS. That includes the fire extinguisher
mounting bracket on the inside of your Paladin’s rear door.
When vibration loosens the bracket, the extinguisher moves around freely.
The next time you open the door from the outside, the door handle can catch
on the fire extinguisher. If you force the door handle, the fire extinguisher valve
trigger breaks off. That discharges the ex-
tinguisher and leaves
you a real mess.
So, check the extin-
guisher bracket as
part of your AFTER
PMCS. Tighten loose
hardware. If the hard-
ware is stripped or
missing, call in your
mechanic.
echanics, the hydraulic check valve, NSN 4820-00-732-3944, for the FAASV’s
auxiliary power unit (APU) is being replaced.
When the check valve goes bad, order check valve, NSN 4820-01-107-6115,
and pipe elbow, NSN 4730-00-852-5654, to replace it.
Here’s how to install the new valve:
1.
With the vehicle shut down, remove the APU pump’s inlet hose and adapter
from the old check valve.
2.
Remove the old valve from the tee. Toss the valve.
3.
Install the new pipe elbow and check valve into the tee. Make sure the valve’s
arrow markings point in the direction of the tee.
4.
Install the adapter
into the check valve,
then reattach the
inlet hose
assembly into
the adapter.
