sion. Overfilling will force fluid out of the case
through the main shaft openings.
Do not mix types or brands of fluid, because of
possible incompatibility. Do not use fluid addi-
tives, friction modifiers, extreme-pressure gear
fluids, or multiviscosity lubricants.
IMPORTANT: Drain the transmission when the
fluid is warm. If not already warm, run the en-
gine until the transmission fluid reaches operat-
ing temperature. Shift the transmission to neu-
tral (N) and shut down the engine.
1.
Apply the parking brakes, and chock the rear
tires. Place a large drain pan under the transmis-
sion.
2.
Clean the area around the fill plug, and remove it
from the side of the gear case. Remove each
drain plug from the bottom of the case.
3.
Clean the fill and drain plugs. For magnetic
plugs, use a piece of key stock or any other con-
venient steel slug to short the two magnetic
poles and divert the magnetic field.
4.
Install each drain plug and tighten them 50 lbf·ft
(68 N·m).
NOTE: For an Eaton Fuller transmission, the
optional transmission fluid filter is a remote-
mount, spin-on type, and is located between the
transmission and the fluid cooler. The filter
bracket is attached to the frame rail or some
other nearby location. The filter is mounted in a
vertical position, and should be filled with fluid
before installation to assure the proper fluid
level. For optimum transmission performance,
change the filter each time that the fluid is
changed.
5.
For an Eaton Fuller transmission equipped with a
transmission fluid filter(s), replace the fluid fil-
ter(s) as follows:
5.1
Place a drain pan under the transmission
fluid filter.
CAUTION
To prevent skin burns from hot transmission fluid,
wear protective gloves when removing the filter.
5.2
Place a strap or chain wrench around the
filter canister, and rotate it in a counter-
clockwise motion to separate the filter
from the mounting. Carefully spin the filter
off the mount and remove it from the ve-
hicle.
5.3
Apply a light coat of transmission fluid to
the O-ring gasket on the new filter. Fill the
filter with specified transmission fluid, and
spin the filter onto the mount.
NOTE: The filter fills slowly, so be patient to
ensure the proper fluid level has been set.
5.4
Once the filter makes contact with the
mount, use a strap wrench to rotate the
canister an additional 180 to 270 degrees
to firmly tighten the filter. Wipe the filter
clean of any fluid after it is tightened.
6.
Add fluid until it is level with the lower edge of
the fill opening. See
Fig. 3
. If the transmission
has two fill openings, add fluid to the level of
both openings. See
Table 3
for approved trans-
mission lubricants, and
Table 4
for transmission
lubricant capacities.
