Tow with drive shafts connected.
If you disconnect the drive shafts to tow the
Fox, the shafts beat a hole in the transmission. So keep the shafts connected during
towing. Your Fox will thank you!
Tires have enough air?
Some Fox units are letting
the tire pressure get too low.
That causes uneven tire wear,
plus vibration during travel,
which hurts the tie rods. The
front tires normally should
have 51 psi and the rest of
the tires 48. Check the psi
on all the tires before you hit
the road.
Close engine grill doors before you turn on AC.
If you forget, no air can go
through the AC condenser and the AC shuts off. You have to reset the AC before you
can turn it back on.
Let probe cool off 15
minutes before putting
cover
back
on.
The
probe can reach 500°F
during
operations.
If
the cover is slid in place
while the probe’s that
hot, things start melting.
Drain air tanks, too.
Drain them after operations. Water collects in the tanks. If
they’re not drained, the air lines and ±ttings are ruined by corrosion.
If it rains, drain.
An amazing
amount of water collects inside
the Fox after a good rain. If that
water isn’t drained out, it can
contaminate the oil in the transfer
case and cause corrosion. Just
open all three drains and leave
them open until all the water
drains out.
Make sure the machine gun turret
ring locks and unlocks.
You don’t
want to ±nd out after you’re in the
±eld that you can’t lock or unlock the
turret. So do both during your monthly
PMCS. Unlock the turret ring and
make sure it rotates like it’s supposed
to. If it turns hard, give the ring some
lubrication. Then lock the ring and
try to rotate it. If it moves, tell your
repairman. He needs to check it out.
Check the boots.
The
shocks, struts, A-arm bars
for the axles, and the tie rods
all have boots. If these boots
are torn or suffering dry
rot, their grease leaks out
and soon you’ve got major
damage. At least monthly,
check all the boots for dry
rot, tears or lack of grease.
