M113-Series FOV…
No Grease Means No Go
C
rewmen, what you don’t see
can
hurt you, especially when it comes to the idler
wheel support arms on your M113-series carrier.
The support arms sit out of
sight behind the idler wheels and
are often covered with mud, so
the grease fittings are easy to
miss.
If you miss too often, the bear-
ings dry out and the idler arm
freezes. When the arm won’t
move, you can’t adjust track ten-
sion. Your vehicle is NMC.
Lube both idler arms with GAA every 150 hours, 1,500 miles or semiannually,
whichever comes first. As always, before you pump in any lube, clean the fittings
with dry cleaning solvent first to keep dirt from mixing with the grease.
Finally, put a dab of GAA on the grease fittings immediately after relubing when
you’ve washed or forded the vehicle. That’ll keep the fittings from rusting.

“Make sure the
stabilization reference
package is bolted down.
The bolt in back of its
box is often forgotten.
Then it bounces up and
down during travel and
messes up the gyros.”
“Check the bolts for the driver's seat.
if they've been left off, the seat can
pitch forward during travel and
throw the driver into the yoke.”
“Open the vent for the chemical
biological reservoir if you plan to
use it. if you run the CBR with the vent
closed, the CBR burns out.”

…but could

for me first?

a
rush
