or years, a homemade deflector was the best way to prevent the M240 machine
gun’s $250 feed tray cover from being crushed when the tank’s main gun was low-
ered. But since units had to make the deflector themselves, a lot of tanks never got
outfitted.
Now a deflector is available
through the supply system for less
than $50. Here’s what to order:
PS 593
M1-Series Tanks…
The new deflector fastens to an existing mounting point on the turret ceiling and
automatically closes an open M240 cover when the main gun is depressed.

NEW DESIGN FOR DRIVESHAFT BOLTS
T
ires on vehicles that sit parked on hard stand in the hot sun for weeks and months
can “wear out” from ozone damage, heat and age.
You see this wear as cracks in the tire sidewall. Once the cracks expose inner
cords or belts, the tire is no longer usable.
To get the most life from your tires, wash them with soap and water, keep them
inflated properly, and use approved rubber preservatives to reduce cracking.
NSN 8030-01-282-5626 gets a gallon of the preservative. Use it as described on
the label.
Commercial products that put a shine on tires are not authorized. They don’t
help the tires and don’t help camouflage your vehicle. So use only authorized
preservatives and get longer life from your tires.

eplacements for the driveshaft end cap bolts on FMTVs are a new, two-headed
design that makes the use of a torque wrench unnecessary.
Bolt, NSN 5305-01-479-7857, has a breakaway second head that snaps off
once
the torque applied to it reaches 30 lb-ft.
So no matter how you tighten the bolt, it
only gets the right torque.
When you have to service the transmission
filters, remove the driveshafts for towing, or any
time you have to loosen or remove the bolts,
replace them.
The bolts cannot be reused.
