Lube the Fox after fording or
rolling through deep mud.
Water
or mud can cause the axle drive pro-
peller shafts, steering axle shafts,
power steering hydraulic cylinder
and marine drive propeller shafts to
lose lube. Without lube, the Fox will
soon stop running down the trail.
Lube the shafts and hydraulic
cylinder with GAA like it says in
the ON CONDITION intervals in
LO 9-6665-376-12.
What you
don’t
want to lube are the brake
bleeder valves on each wheel. They
look like lube fittings, but they’re
not. If you get grease in the valves,
you can’t bleed the brakes.
For Repairmen Only
Torque the collar for the
main prop shaft to 90-100
lbs/ft.
If you don’t, the shaft’s
splines work loose and are
damaged. Then the prop shaft
and flanges must be replaced.

Fox NBC Vehicle.…
A
ll of the Fox’s expensive, sophisticated sensing equipment won’t make much
sense if the Fox doesn’t have the legs to get to the danger zones. That’s why it’s
important not to forget the Fox vehicle. Here are some ways to keep it moving:
Do not disconnect the main drive
shaft if you must tow the Fox.
Some
Fox units think if you don’t discon-
nect the drive shaft before you tow, the
transmission will be damaged. It’s just
the opposite. If you disconnect the
shaft, it turns during towing and tears
up the transmission and main flange
of the drive shaft. See Procedure
APG-Fox-10-O-230 in TM 3-6665-
339-10 for towing instructions.
Bleed the air tanks after every
operation.
The task is part of the after
operations PMCS in the -10. The air
tanks have alcohol reservoirs that keep
moisture in the air tanks from freez-
ing. But if too much moisture gets in
the system, the alcohol becomes too
diluted and moisture can freeze in the
brake lines. The results would not be
pleasant. To get at the three bleed
points, you must remove the access
cover to the air tanks. See Step 74 in
Procedure APG-Fox-10-M-001 in the
-10 for instructions.
Remove access cover to bleed valves
Torque collar bolts to 90-100 lbs/ft
Keep grease
away from brake
bleeder valves
