our D7G dozer is the Army’s workhorse for moving tons of dirt. But even a
Clydesdale needs a little TLC to stay mission-ready.

Stay Level
Park on a level surface. Never
park your dozer on the side of a
hill overnight. Besides being
unsafe, this puts a strain on the
roller seals and causes them to
leak. Rollers only hold a pint of
oil. Without oil, the roller grinds
itself up in a few hours.
Put Slide Back in Linkage
Shifty Business
Slow
and
easy
is the best way
to shift the dozer from neutral to
reverse. Slamming the shifter
sideways from neutral,
then
down into reverse, will break the
backup alarm’s magnetic switch.
A busted switch means the back-
up alarm won’t sound off in
reverse. Then the dozer is NMC.
Keep Slave Receptacle Dry
Keep the dozer’s NATO slave receptacle from becoming a water container by
keeping the dust cap in place.
The receptacle faces straight up—just the right angle to hold water if the cap’s
missing. Once in the receptacle, water corrodes and rusts the receptacle’s metal con-
tacts. In winter, it can freeze in the receptacle, and then you can’t slave start a dead
vehicle. Worse, that frozen water—ice—
could crack the receptacle as it expands.
So do yourself a favor and make sure
the dust cap is in place and snug. If the
cap and cable assembly is missing,
replace it with NSN 5340-01-059-0114.
Until a new cap comes in, cover the
receptacle with electrical or duct tape.
Moisture corrodes the linkage for the governor control lever (throttle) and causes
it to push or pull sluggishly, erratically or not at all. A stuck lever isn’t much good
when you need to increase or decrease engine speed during operation.
So wipe off the throttle linkage with a brush or
clean rag at every scheduled service. Then spray with
a shot of lubricating spray, NSN 9150-00-458-0075.
Work the throttle lever back and forth a few times.
Lube puts the slide and glide back into the linkage for
smooth operation of the throttle.
