M9 ACE…
Don’t Throw a Track!
S
ome have found out
the hard way, the impor-
tance of the words on
Page 2-69 of TM 5-
2350-262-10.
Never
steer the ACE
during dozing opera-
tions! Turning the wheel
while dozing puts so
much stress on the track
that it can be thrown.
Thrown track can crack
road wheels, bend road
arms and rip actuators
from the hull.
And during opera-
tions, forget sharp turns.
You can throw a track
that way, too.

Packaging Info
The excavator’s engine and
transmission suffer unnecessary
damage when they’re not pack-
aged right.
With the engine removed, do
not leave the transmission
exposed to the elements. That’s
because water collects in the
housing. During low tempera-
tures the housing can crack when
the water freezes. Also, water
rusts the input shaft’s collar.
The engine can also suffer
damage if left exposed to the ele-
ments. All that’s needed during
packaging is a little TLC. Pack
the engine and secure it in a
wooden crate if possible. If the
engine is secured (strapped
down) to a wooden pallet, do not
leave it exposed to the elements.
Make sure it’s covered with plas-
tic wrap. It’s the smart way to
save your unit unnecessary
repair bills down the road.
Ban the Birdbath
Do not run the excavator through
the birdbath for cleaning. When
water sits in the clutch group, it
rusts the collar on the input shaft.
Eventually, the throwout bearing
seizes and the clutch won’t work.
Then you’re stuck with a vehicle
that won’t shift gears.
Next time your excavator needs a
bath, spray it with a high-pressure
hose instead.
no
sharp
turns,
either.
yep.
geez! we
shouldn’t
have
steered!
yep!
that

not needed.
