Reminder
I
f your unit has FMTV A1P2 trucks with serial numbers below 737,560, or
LVAD
model
M1081A1
and
M1093
trucks
within
serial
number
range
L-T120386EHFV to M-T120972EHBW,
your truck’s spare tire lifting eye studs
could fail.
And that can lead to the entire 363-lb wheel and tire assembly falling,
injuring personnel and damaging equipment.
Thankfully, this preventable problem doesn’t make your truck NMC. The trouble
was created during vehicle production when the spare tire lifting eye nuts on these
trucks were over-tightened. The resulting slightly stretched studs in turn weakened
the stud threads.
The
lifting
eye
assembly
secures the chain used to lift
the spare tire. Both eye nuts are
screwed onto a common stud.
When the spare wheel and tire
assembly is lifted from the truck,
the lifting eye assembly supports
the full weight of the spare tire
while aloft.
Prevent a possible failure by
replacing the eye nut studs, NSN
5307-01-416-9968. Install them
with the proper torque value of
44 ft-lbs.
Until
stock
runs
out,
replacement studs will be issued
at no cost to units. For ordering
instructions, contact TACOM’s
Crystal Simmons at DSN 786-
6642, (586) 282-6642, or email:

c
rewmen, make sure the circuit breakers
in your M1117 armored security vehicle
(ASV) are switched OFF after the day’s run.
If the breakers are left ON–especially
the one for the transmission–the vehicle
batteries will drain in no time.
So, switch off the breakers right before
you turn off the engine. That way you’re not
stuck with dead batteries the next morning
when it’s time to start up the vehicle!
