To find the service requirement, look
in the lubrication order. That’s not a mis-
print, mechanics. It’s in the lube order,
Appendix H of TM 9-2320-365-20-5
and TM 9-2320-366-20-5. You’ll be
referred to Para 23-6 in the -365-20-5
TM or Para 23-11 in the -366-20-5
where the air dryer removal and installa-
tion instructions are found.
There you’ll see how to remove and
replace the desiccant cartridge and
check the heating element that removes
moisture from the air before it goes to
the primary and secondary air tanks.

Dear Editor,
During a routine training mission,
one of our 2 1/2-ton FMTVs caught
fire behind the instrument panel.
Investigation and troubleshooting
determined that the fire started at
the heater fan switch.
There are exposed coils on the rear
of the switch, and they get very hot
during use. Anything close enough to
the coils is likely to burn. And there
are many wires behind the panel that
can be too close.
Wire too
close to coil
Did you know the air dryer carries a
12-month or 12,000-mile service
requirement, whichever comes first?
So we tied up the wires to get them
as far away from the switch as possible.
A simple inspection of the area behind
the instrument panel near the switch
could save you a truck–and some lives.
