Without that exercise, the control
cable gradually loses its lubrication.
The
gear
lock
lever
slowly
gets
stiffer until it eventually seizes up
completely. That means risking a
runaway vehicle if you park on a
slope greater than 30 degrees, even
with the parking brake engaged.
Exercising the transfer case
gear lock is simple and takes
only a few seconds. Just pull
and rotate the gear lock lever
towards
the
driver.
While
the
gear
lock
is
engaged,
double-check
to
make
sure
the parking brake LED lights
up on the driver’s panel. To
disengage, push and rotate the
lever away from the driver.
You’re done!
y
ou can’t judge a book by its cover, crewmen. That’s especially true when it comes to the
pivot steer brake assembly hydraulic bleeder valves in the M113A2 family.
The valves may look a lot like
grease fittings, but they’re not.
Grease clogs the valves and
keeps you from bleeding the
system. Cleanup is no fun,
either. Your mechanic will have
to remove the bleeder valves
and clean them with solvents
and compressed air.
It’s easy to prevent this
problem, though. Just make
sure you keep the grease gun
away from those valves the
next time you lube.

small change,

big
dividends!

Hey!
You
didn’t
set my
transfer
case gear
lock!
I tried, but
the lever
wouldn’t pull
out. S’okay,
though. The

is set.

enough when the

more
than 30 degrees!

ya!
