f tight is good, then tighter must be better. Right, crewmen?
Not when it comes to the transmission oil dipstick. After checking the oil level
before and after operation, you have to turn the T-handle on the dipstick to lock it in
place. Turning the T-handle makes the gasket under the top of the dipstick expand to
completely seal the opening.
But if you turn the T-handle too far, the dipstick can pop loose like a cork, espe-
cially after a few road bumps during operation. With a loose dipstick, it’s easy for
water from cleaning or low-water fording to get splashed into the neck and contam-
inate the transmission.

M577-Series Command Post Carrier…
never forget the lever
y
ou want your M577’s 4.2-KW gener-
ator to be full of hot air during the win-
ter, not the summer, crewmen. That’s
why the engine air shutter has a SUM-
MER/WINTER lever.
During cold weather, setting the
lever to WINTER deflects cold incom-
ing air past the exhaust manifold. The
preheated air makes for easier restarts
and a smoother run.
Unfortunately, some crewmen forget
to move the switch back to SUMMER
when the temperatures go back up.
Already hot air becomes scorching.
The generator’s air filter is toast.
So do your 4.2-KW a favor. Flip the
engine air shutter lever to WINTER
when it’s cold and to SUMMER all the
rest of the time.
Flip lever to WINTER
during cold weather…
…and SUMMER
all other times
whew!
sure is a
hot one
today!
it would be a
lot
cooler
if
you’d flip my
air shutter
lever to
summer!
oops!!
my
transmission
oil dipstick
popped
loose!
keep
that
water
away!
Then, take a
gander at it
every now and
then to make
sure it’s still
firmly in place.
So go
easy when
locking
the dip-
stick in
place.
Secure dipstick by
turning T-handle—
but
not too much!
