Use puller 99348001 (3) to remove the rear taper roller
bearing (2) from the bevel pinion (1).
Differential components check
Carefully clean each differential component.
Lubricate the bearings and rotate the roller cage freely. The
rotation must be even and without sign of stiffness. Check the
ring bevel gear contact surfaces and the half-box striker plate
to ensure that the crown wheel adheres perfectly. Deforma-
tions on these surfaces cause the crown wheel fastening
screws to vibrate, thus jeopardizing the correct operation of
the unit.
NOTE
Carefully clean all threads in order to obtain exact
adjustments and accurate tightening torque.
Check that the splined section for flange-pinion connection is
not badly worn, otherwise replace the pinion.
NOTE
When replacing the crown wheel or pinion it is
necessary to replace both parts since they are
supplied in pairs.
Check the planetary gears and the relevant shoulder
washers, the spider and the crown wheels with the relevant
shoulder washers.
Replace all sealing elements, the bevel pinion retaining nut
and gearing case bearing adjustment nut with new parts.
Rear axle casing check
Check whether rear axle casing is not deformed.
