Fuller Transmission Oil Filter
Element Changing

After draining the transmission case, remove the
attaching bolts and filter cover from either one or
both power take-off openings in the case.

Remove and discard the filter element(s).

Install the new filter element in the power take-off
opening in the case.

Attach the cover to the case with the attaching
bolts. See Group 00 in this manual for torque
values.

Fill the transmission with recommended clean oil,
as instructed under "Manual Transmission Oil
Changing."

26–07 Transmission Air Filter/

Regulator Checking, and
Cleaning or Replacing

Fuller Transmission

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.

Apply the parking brakes and chock the tires.
Drain the air from the air reservoirs.

Clean the outside of the air filter/regulator with
cleaning solvent, then let it air dry. See

Fig. 9

Remove the end cap, large O-ring, and filter ele-
ment from the filter housing. See

Fig. 10

. Re-

move 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 the air pressure between 58 and 63 psi (400
and 434 kPa), replace the air filter/regulator,
which is not serviceable.

WARNING

Wear eye protection when using compressed air
to clean parts, as permanent harm to eyes could
result from flying debris.

Clean the filter element by dipping it in alcohol or
other cleaning solvent. Blow compressed air
through the filter element (inside to outside) to
loosen surface dirt and to dry the element. If it is
not damaged, the sintered metallic filter element
will last the life of the vehicle.

Wipe out the filter housing with a clean, dry, lint-
free rag. Clean and inspect the O-rings and the
end cap. Replace any parts that are damaged.

Install the large O-ring, then the filter element
(small end first) into the filter housing.

Install the small O-ring in the end cap, then in-
stall the end cap and tighten it 8 to 12 lbf·ft (11
to 16 N·m).

Start the engine, and build pressure in the air
system. Check for air leaks at the filter housing
and air line connections; repair any leaks.

CAUTION

A leaking air filter or air lines can cause slow or
hard shifting of the transmission, and eventual
transmission damage.

Spicer Transmission

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.

Apply the parking brakes, and chock the tires.
Drain the air from the air reservoirs.

Clean the outside of the air filter/regulator
(

Fig. 11

) with cleaning solvent, then let it air dry.

Loosen or remove the air filter/regulator bracket
clamp, then unscrew the bowl; hold the regulator
to prevent it from turning. Remove the O-ring.

Unscrew the stud from the regulator. Remove the
louver, upper gasket, element, and lower gasket
from the stud.

WARNING

Wear eye protection when using compressed air
to clean parts, as permanent harm to eyes could
result from flying debris.

Clean and inspect all parts. Use only a
petroleum-based solvent to clean the parts. Blow
air through the filter element (inside to outside) to
loosen surface dirt.

IMPORTANT: After three cleanings, replace the
filter element with a new one.

Do not disassemble the regulator, as it is not
repairable. If the air regulator does not work
properly, replace the unit.

Install the lower gasket, the cleaned or new ele-
ment, the upper gasket, and the louver, on the
stud. Install the element so the large end of the
internal taper (thinnest wall section) is toward the
hex on the stud.

Install and tighten the stud 5 to 10 lbf·in (60 to
100 N·cm).

Apply a light coat of Dow Corning DC7 silicone
grease, or an equivalent, to the O-ring seating
surfaces on the regulator and the bowl.

Apply a light, even coat of Molykote "G," or an
equivalent, to the bowl threads. Install and
tighten the bowl 5 to 10 lbf·in (60 to 100 N·cm).

10. Install and/or tighten the air filter/regulator

bracket clamp.

11. Install and torque the drain valve, if removed, 10

to 15 lbf·in (120 to 160 N·cm).

12. Build air pressure in the system, check for leaks,

and make any necessary repairs.

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.

Apply the parking brakes and chock the tires.
Drain the air from the air reservoirs.

Clean the outside of the air filter/regulator with
cleaning solvent, then let it air dry.

Remove the end cap from the air filter/regulator
assembly, then inspect the O-rings in the end
cap. Replace worn or damaged O-rings.

Remove the element from the filter/regulator as-
sembly.

Inspect the element for oil. If oil is in the ele-
ment, replace the element. Inspect the air supply
system for the source of oil, and service it as
needed.

Install the element in the filter/regulator assem-
bly.

Apply a light coat of Dow Corning DC7 silicone
grease, or an equivalent, to the O-rings in the
end cap.

Install and tighten the end cap 10 to 15 lbf·ft (14
to 20 N·m).

Build air pressure in the system, check for leaks,
and make any needed repairs.

26–08 Transmission Oil Level

Checking and Breather
Checking

NOTE: For vehicles with auxiliary transmissions,
use this procedure to check the auxiliary trans-
mission oil level and breather whenever check-
ing the main transmission oil level and breather.

Breather Checking

Transmission housing breathers must remain clear. A
plugged breather could result in pressure build-up,
which could cause oil leakage.

If the breather is plugged, clean or replace it. See

Fig. 7

. Check more often if the vehicle operates

under very dusty conditions.

Allison Transmission

CAUTION

Operating a transmission with the fluid level
higher or lower than recommended can result in
transmission damage. Do not overfill the transmis-
sion.

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.

Cold Check

Clean all dirt from around the end of the fluid fill tube
before removing the dipstick. Do not allow foreign
matter to enter the transmission. Dirt or foreign mat-
ter in the hydraulic system may cause undue wear of
transmission parts, make valves stick, and clog pas-
sages.

It is important to check the fluid level while cold to
determine if the transmission has a sufficient amount
of fluid to be safely operated until a hot check can be
performed.

Park the vehicle on a flat, level surface.

Apply the parking brake and chock the tires.

Run the engine for at least one minute.

Shift from DRIVE to NEUTRAL, and then shift to
REVERSE to fill the hydraulic system.

Shift to NEUTRAL and allow the engine to idle at
500 to 800 rpm.

With the engine running at idle, remove the dip-
stick from the tube and wipe it clean.

Insert the dipstick into the tube and remove the
dipstick.

Check the fluid level reading and repeat the
check procedure to verify the reading.

If the fluid level is within the COLD RUN band,
the transmission may be operated until the fluid
is hot enough to perform a hot check.

If the fluid level is not within the COLD RUN
band, add or drain fluid as needed to adjust the

Transmission
