Dear Editor,
The brake system connections on
M870A1 trailers are in such an awkward
position that when we hook up our
M916A1 tractor’s air hoses, the hoses
are in a tight bend. Over time,
the bend-
ing fatigues the hoses, leading to leaks.
Since air hoses are not cheap, I
solved the bending problem.
I installed a 45° street elbow, NSN
4730-00-595-0143, between the
hose and connector on the tractor’s air
hoses. Then I put antiseize tape, NSN
8030-00-889-3535, on the threads
to seal the connection.
The air hoses can then be hooked up
to the trailer connector at an angle that
won’t create leaks.

D
oing maintenance in the desert is more than just a dirty job: Anything covered
with grease or oil attracts dust and sand like a magnet.
Sand and dust combine with grease and oil to make a gritty combo that works like
scouring powder on metal surfaces and rubber seals.
But you can’t avoid maintenance in the desert, just like you can’t shut out sand
and dust completely. Here’s what you can do:
You should also tag the bags to
make sure everything goes back on
exactly where it came off.
➔
Keep sand and dust off
repair and replacement parts
while you’re making repairs by
wrapping greased parts with
waxed paper or newspaper.
➔
Use plastic wrap to keep
dust and sand out of open
components. NSN 8135-00-

➔
Use plastic bags to hold bear-
ings and small parts like nuts and
bolts that might get lost or dirty
before you need them again.
Here are some
