M989A1 Heavy Expanded Mobility
Ammunition Trailer’s air brake parts have
changed. Note these new numbers in Fig
13 of TM 9-2330-383-14&P:
M149A2 Water Trailer Tanks
All M149A2 water trailers should now have stainless steel tanks. If your trailer still has
a fiberglass tank, turn in your old trailer, and request a trailer with the steel tank, NSN
2330-01-108-7367. The new trailer is free to Army units. Non-Army units should add a fund
cite for transportation costs in the Remarks block of the requisition.

NSN 2530-01-179-7640 gets a brake shoe kit for the 34-ton flatbed trailer. The kit includes
two shoes with linings and everything needed to do a brake job on one wheel. This kit
takes the place of Items 2 through 10 in Fig 14 of TM 9-2330-359-14&P.
M915A1 Brake Shoe Kit
NSN 2350-01-437-3324 gets a front axle
brake shoe kit (including linings) for the
M915A1 tractor truck. The kit shown as
Item 8 of Fig 83 in TM 9-2320-283-24P is
no longer available. DS can get just the
brake lining kit by asking for PN 807167
CAGE 52304 from RIC S9C on a DD Form
1348-6. The kit has eight linings and
enough rivets to do one front axle.

0112 (quart), and rubber buffing solution,
NSN 2640-00-403-5539 (gallon), are no

(16-oz can), instead.

The hydraulic breather for the M1000 HET
semitrailer’s gooseneck is back in the
