T
ire chains for your wheeled vehicle are usually listed in the additional authoriza-
tion list (AAL) in the -10 TM. But not all -l0s have the info.
Plus, the TMs don’t give you replacement cross chain and swivel hook NSNs for
the chains. So here is the right chain info for some common tire sizes:

2 1/2-Ton, 5-Ton Trucks…
Wiper Motor Needs Exercise
O
perators, "use it or lose it" applies to your M44A2-series 2 1/2-ton or M809-
series 5-ton truck's air-actuated wiper motor, too.
Left unused, rust can build up on the shaft of the windshield wiper motor and
keep the motor from working when you need it most.
So give rust the boot. When you hop into your truck, reach up and give the wipers
some exercise by moving the manual paddle lever back and forth. That'll spread any
lube left on the shaft. If the lever catches or won't move freely, get your mechanic
to work it over like so:
Remove the wiper motor like it says in the TM.
✔
Lift the rectangular inspection cover from the motor.
✔
Line up the screw in the center of the inspection hole and remove it.
✔
Squirt 10W oil between the shaft and the bushing to loosen the rust.
✔
Install a nut on the threaded end of the shaft. Gently tap the shaft until it's loose.
Remove the nut and pull the shaft out of the bushing and motor.
✔
Remove rust from the
shaft and interior of the
bushing with steel wool, fine
sandpaper or emery cloth.
✔
Coat the shaft with GAA.
Install the shaft,
center
screw and inspection cover.
✔
Install the wiper motor. If
the motor still won't work
right, replace it with NSN

If dual tire chains for your tire size are not listed here, use singles on the outside
tires. Parts are the same for single and dual chains of the same size.
If your vehicle has a tire size not listed here, have your supply clerk check out
FSC 2500 in FED LOG for other chains. Authority to order chains comes from
Appendix A, CTA 50-970.
