Not Available
n most cases, your operator’s manual provides an NSN for tire chains
in the additional authorization list (AAL). But not every -10 TM has
the info.
Plus, the -10s don’t give you replacement cross chain and swivel
hook NSNs for the chains. So, here are some common tire sizes and
the right chain info:
Wheeled Vehicles . . .
If dual tire chains for your size tires are not listed here, use singles
on the outside tires. Parts are the same for same-size single and dual
chains.
If your vehicle has a tire size not listed here, have your supply clerk
check out FSC 2500 for other chains. Authority to order chains comes
from Appendix A, CTA 50-970.
Remove protective cover.

M939/A1/A2-Series Trucks . . .
Snub No Grease Fittings
O
perators, overlooking the three grease fittings on your 5-ton truck’s steering
gear shaft now can mean hard or erratic steering later.
But, some of you
are
overlooking those fittings, especially the one at the
U-joint under the steering pump’s protective box.
Make sure each fitting gets four or five shots of grease during scheduled
service.
