T
he engine cooling fan system in your dozer is designed to move air through the
radiator when the vehicle is moving slowly or stopped. The air Fow removes heat
from the engine coolant in the radiator.
Here are two PM pointers that keep the dozer’s fan system operating smoothly.
Grease Fitting Reminder
One
grease
±tting
that’s
often
overlooked during scheduled services is
the one that lubes the fan pulley bearings.
It’s hidden behind the fan blades.
Without lube, the bearings seize up.
Then the blade stops turning freely and
the engine and transmission overheat.
Keep the fan pulley bearings lubed.
During scheduled services, give all the
±ttings four or ±ve pumps of grease.
Open Air Flow
Any dirt or mud caked on the fan blade
screen stops the air Fow that carries heat
away from the radiator. Blocked air leads
to engine and transmission overheating.
So, clean off dirt or mud with low-
pressure water or air.

Do you have these batteries:
±
Is there an operator-level TM available for
each piece of equipment?
Are there adequate supplies of calcium
hypochlorite and cleaning materials to sanitize
and maintain masks?
Does each mask have all of its components
and is it properly stored?
