MAINTENANCE MANUAL - Meritor

CAUTION
USE A PRESS AND A SLEEVE OR FORk IN-
STALLATION TOOL TO INSTALL THE FORk.
DO NOT USE A HAMMER OR MALLET. USING
A HAMMER OR MALLET CAN DAMAGE THE
BEARINGS, FORk OR FLANGE.
If a fork is removed after it has been partially
or fully installed, the unitized pinion seal will
be damaged. Remove and discard the original
unitized pinion seal and replace it with a new
one.
If a fork has been installed into the unitized pinion
seal and then removed, the inner sleeve of the
seal will be damaged. Install a new seal.
3. Use a press and sleeve or an installation
tool to install the fork or flange in the output
shaft. Verify that the splines inside the fork
or flange are aligned with the splines on the
toutput shaft. If a press and sleeve are used,
verify that the output shaft is supported.
4. Install the nut that fastens the output fork or
flange to the output shaft. Place a holding tool
on the fork or flange and tighten the nut to the
specified torque. See the Section 8.
5. Rotate the fork at least one full turn after
the fork nut is tightened to the correct
torque specification. This ensures correct
seating of the seal.

1. Use a cleaning solvent and rags to clean the
inside of the axle housing and the differential
mounting surface. See the Section 4.
2. Inspect the axle housing for damage. Repair or
replace the axle housing. See the Section 4.
3. Check for loose studs, if equipped, in the
mounting surface of the housing where the
differential fastens. Remove and clean
the studs that are loose.
4. Install the studs in the axle housing. See the procedure
in this section. Tighten the studs to 150-
230 lb-ft (203-312 Nem). .
WARNING
When you apply some silicone gasket materials,
a small amount of acid vapor is present. To prevent
serious personal injury, ensure that the work
area is well-ventilated. Read the manufacturer’s
instructions before using a silicone gasket material,

CAUTION
APPLY SILICONE GASkET MATERIAL IN A
CONTINUOUS 0.25-INCH (6 MM) BEAD. IF YOU
USE MORE THAN THIS AMOUNT, GASkET
MATERIAL CAN BREAk OFF AND PLUG LU-
BRICATION PASSAGES. DAMAGE TO COM-
PONENTS CAN RESULT.
5. Apply a 0.25-inch (6 mm) continuous bead of
silicone gasket material to the mounting surface
of the housing where the differential fastens.
