old weather will turn any moisture in your truck’s air brake lines into ice, block-
ing the lines. That leaves you brake-less.
So if your vehicle has an alcohol evaporator to keep moisture out of the air lines,
make sure it contains the alcohol it needs to do the job.
NSN 6810-00-275-6010 gets a 5-gal can of technical methanol. NSN 6810-00-
224-8353 gets a 55-gal drum.

Y
ou won’t find the 4-prong, spring-back starter switch for M35A2 and M35A3
trucks in paper versions of TM 9-2320-361-20P or TM 9-2320-386-24P. Get the
switch with NSN 5930-01-334-2862. The switch is shown as Item 31 of Fig 56 in
the May 01 version of TM 9-2320-386-24P on EM 0037.

Bigger Shackle Takes Bigger Hook
Y
ou drivers need to pay more attention to
the front shock absorber bushings on your
FMTVs. That’s because the shock mounts
pivot to allow movement of the front axle
from side to side and forward and backward.
So the bushings get a lot more wear than
normal. It means that when you pull the
weekly PMCS for shock absorber leaks and
missing hardware, you need to check out the
bushings, too.
Once the bushings are shot, suspension damage is next—and that ain’t cheap.
W
hen heavier towing shackles are added to your tactical vehicles—to meet air
transport requirements—old-style trailer safety chain hooks won't work with them.
You'll need larger hooks for the larger shackles.
Replace the old chain hooks with hook, NSN 4030-01-438-1803. It works on the
larger shackles and is easy to install.
Cut the trailer chain's last link, or remove its removable link. Discard the old
hook. Install the new one with the pin and cotter pin that come with it.

Tarp for M1077/ISO Flatrack
T
he NSN shown for the tarp used on the M1077 and the ISO-compatible pal-
letized flatracks in Figs 1 and 9 of TM 9-3990-206-14&P is wrong.
Make a note
until the TM is updated that NSN 2540-01-457-0049 brings the correct tarp.
