8. Clean the fill plug, then install it in the transmis-
sion. Tighten the plug as follows:
•
25 to 35 lbf·ft (34 to 48 N·m) for Eaton
Fuller transmissions with 3/4-inch pipe
threads.
•
60 to 75 lbf·ft (81 to 102 N·m) for Eaton
Fuller transmissions with 1-1/4-inch pipe
threads.
•
44 lbf·ft (60 N·m) for all ZF Meritor
FreedomLine automated transmissions.
•
35 to 50 lbf·ft (48 to 67 N·m) for all other
Meritor transmissions.
9. Operate the vehicle to check for correct opera-
tion.
26–02 Transmission Fluid
Level Inspection
NOTICE
Operating a transmission with the fluid level
higher or lower than recommended can result in
transmission damage. Do not overfill the transmis-
sion. Overfilling will force fluid out of the case
through the main shaft openings.
Do not mix types and brands of fluid, because of
possible incompatibility. Do not use fluid addi-
tives, friction modifiers, extreme-pressure gear
fluids, or multiviscosity lubricants.
With the transmission at operating temperature, and
the vehicle on a level surface, check the fluid level in
the transmission.
1. Clean the area around the fill plug, and remove it
from the side of the gear case.
2. Using your finger or a bent pipe cleaner, see if
the fluid is level with the fill opening. See
Fig. 1 .
3. If the fluid level is low, check the transmission for
leaks, and correct as needed.
4. If needed, add the recommended fluid, until it is
level with the lower edge of the fill opening. See
Table 1 for approved transmission lubricants.

Eaton approved lubricants, refer to the Eaton

mation and a complete listing of Meritor ap-
proved lubricants, refer to the ZF Meritor web-
site,

5. Clean the fill plug, then install it. Tighten the plug
as follows:
•
25 to 35 lbf·ft (34 to 48 N·m) for transmis-
sions with 3/4-inch pipe threads.
•
60 to 75 lbf·ft (81 to 102 N·m) for transmis-
sions with 1-1/4-inch pipe threads.
•
44 lbf·ft (60 N·m) for all ZF Meritor
FreedomLine automated transmissions.
•
35 to 50 lbf·ft (48 to 67 N·m) for all other
Meritor transmissions.
26–03 Manual Transmission Air
Filter/Regulator Check,
Cleaning, or
Replacement
Eaton Fuller
1. Apply the parking brakes, and chock the rear
tires. Drain the air reservoirs.
WARNING
Drain the air supply; if the air supply is not
drained before the air filter/regulator is serviced,
serious injury and component damage could re-
sult.
2. Clean the outside of the air filter/regulator with
cleaning solvent. See
Fig. 2 .
3. Remove the end cap, large O-ring, and filter ele-
ment from the filter housing. See
Fig. 3 . Remove
the small O-ring from the end cap.
NOTE: Do not remove, disassemble, or adjust
the air regulator. If the air regulator is not keep-
ing air pressure between 58 and 63 psi (400 to
435 kPa), replace the air filter/regulator. It can-
not be repaired.
WARNING
Wear safety goggles when using compressed air
to clean parts, as permanent harm to eyes could
result from flying debris.
