D7G Tractor…
Keep Battery Cables Able
As a tractor operator,
you might give a dozer’s
batteries low PM priority.
After all, you can’t do
any more than eyeball the
batteries, cables, cables
and battery box.
Missing a Grommet?
A missing grommet can stop your dozer dead in its tracks. It may sound hard to
believe, but it’s true.
For instance, take the grommets that protect the D7G’s battery cables as they
pass from the battery box into the transmission control group housing.
Weather deteriorates grom-
mets and vehicle vibration
loosens them. Once the grom-
mets are gone, the metal edges
of the housing or battery box can
cut cables’ rubber insulation.
That can ground the battery
and shut down the vehicle. It
could also burn or shock anyone
touching the vehicle.
So eyeball the grommets to see if they’re loose, missing or dry-rotted. They
should fit snugly in the holes. If they need replacing, use NSN 5325-01-176-8163.
Charging?
After you start your tractor and before
you start operations, make sure the bat-
tery indicator or ammeter gauge is in the
CHARGE range.
All that bouncing around in the rough
stuff loosens your tractor’s battery
clamps. A loose connection keeps your
batteries from re-charging. It also keeps
your dozer from starting.
No charge?
Check the clamps.

But don’t forget that
your eyes see battery
problems first. If you
don’t report what you
see, you have no one
else to blame if those
batteries let you down.

things
