circulated by the motion of gears and
shafts. Grey iron parts have built-in
channels where needed to help lubricate
bearings and shafts. All parts will be amply
lubricated if these procedures are closely
followed:
1.
Maintain oil level; check it regularly.
2. Change oil regularly.
3. Use the correct grade and type of
oil.
4. Buy oil from a reputable dealer.
Lubrication Change and Inspection
Off-Highway Use
Refer to the Eaton Fuller transmission
manual for servicing information.
Highway Use
• Refer to the Eaton Fuller
transmission manual for servicing
information.
• Refer to the oil change vs.
temperature chart that follows for
special oil change information. The
"intermittent peak temperature" is
the maximum temperature
observed for a short time in a fully
loaded vehicle performing normally.
CAUTION
Exceeding the recommended oil
change intervals may be harmful to the
life
of the transmission and the trans-
mission oil cooler.

should be made any time after 3000 miles
(4800 km) but never longer than 5000
miles (8000 km) of over-the-road service.
In off-highway use, the change should be
made after 24 hours but before 100 hours
of service have elapsed.
Refilling
Remove all dirt around filler plug. Refill with
new oil of the grade recommended for the
existing season and prevailing service. Fill
to the bottom of the level testing plug
positioned on the side of the transmission.
Do not overfill the transmission. Overfilling
usually results in oil breakdown due to
excessive heat and aeration from the
churning action of the gears. Early
breakdown of the oil will result in heavy
varnish and sludge deposits that plug up oil
ports and build up on the splines and
bearings. Overflow of oil can also escape
onto clutch or parking brakes. When
adding oil, do not mix different types of oil.
Fuller Transmission Lubrication
Fuller transmissions are designed so that
the internal parts operate in a bath of oil
