LUBRICATION
Proper
Lubrication .
..
the Key to long
transmission life
Proper lubrication procedures are the key to a good all-
around maintenance program.
If
the oil is not doing its
job, or if the
oil level
is
ignored, all the maintenance
procedures
in
the world are not going to keep the
transmission running or assure
long transmission life.
Eaton Fuller Transmissions are designed so that the
internal parts operate
in
an oil circulating bath by the
motion of the gears and shafts.
Thus,
all parts are amply lubricated if these procedures
are
closely followed:
1.
Maintain oil level. Inspect regularly.
2. Change oil regularly.
3. Use the correct grade and type of oil.
4.
Buy from a reputable dealer.

The use of mild EP gear oil or multi-purpose gear oil
is not recommended, but
ifthesegearoilsare
used,
be sure to adhere to the
following limitations.
Do
not use mild EP gear oil or multi-purpose gear oil
when operating temperatures are above 230° F (110"
C).
Many of these gear oils, particularly 85W140,
break down above 230° F and coat seals, bearings, and
gears with deposits that can cause premature
failures.
If
these deposits are observed (especially a coating on
seal areas causing oil leakage), change
to
Eaton
Roadranger
CD50 transmission fluid, heavy duty en-
gine
oil, or mineral gear oil to assure maximum compo-
nent
life and to maintain your warranty with Eaton.
(Also see "Operating Temperatures".)
Additives and friction modifiers are not recommended
for use
in
Eaton Fuller Transmissions.
Proper Oil Level
Proper Oil Level
Make sure oil is level with the filler opening. Because you
can reach
oil with your finger does not mean oil is at
proper
level. (One inch of oil level is about one gallon
of
oil.)
Draining Oil
Drain transmission while oil is warm. To drain oil remove
the drain
plug at case bottom. Clean the drain plug
before re-installing.
Refilling
Clean case around filler plug and remove plug from case
side.
Fill the transmission to the level of the filler opening.
If
the transmission has two filler openings, fill to the level
of both openings.
The exact amount of
oil depends on the transmission
inclination and model. Do not over
fill-this
causes oil to
be forced out of the case through the front bearing cover.
When adding
oil, types and brands of oil should not
be mixed because of
possible incompatibility.
