Mount the spindle (6). Lubricate the new seal (5) and fit it on
the piston (4) and insert this into the cylinder (3). Apply sealant
on the thread of the cylinder (3) and screw it down into the
differential casing, tightening it to the prescribed torque.
Screw down the screw (2) so as to provisionally prevent the
differential gear unlocking.
Remove the differential casing from the mounting and fit it
back on the axle housing as described under the relevant
heading.
!
If the spring pin or the split pin do not coincide with
their respective seats on the ring nuts, slightly turn
these so it is possible to insert the spring pin or the split
pin,

Block rotation of the flange (1) using tool 99370317 (2); with
wrench 99355088 (3) and multiplier (4) tighten the nut
fastening the flange (1) to the prescribed torque.
Fit on the cover (5) with a new gasket.
Remove the differential casing — transfer box from the
mounting 99322228 and fit it back on the axle housing as
described under the relevant heading.
Position on the differential casing the adjustment rings (2) of
the thickness determined under the heading “Adjusting drive
input shaft bearing end float” and fit on the mount (1)
comprehensive of the reduction gear transfer box.

Mount the differential locking - transfer box (Figure 52, page
135) and adjust it as described under the heading, “Adjusting
differential locking-transfer box pin limit switch.”
Stop rotation of flange (1) with retainer 99370317 (3). With
wrench 99355131 (2) and torque adaptor (4) loosen shaft
flange (1) retaining nut.
Removing retaining nuts (5) and separate shaft bearing cage (6)
from axle housing.
Tighten the drive output shaft (3) in a vice; remove the nut
securing flange (2) to drive output shaft (3) and dismantle
flange (2) from shaft (3) using an extractor.

Reverse the removal operation sequence to reassemble the
output shaft unit.
After fitting the O-ring (3) with tool 99374163, use a feeler
gauge to check distance X between sealing ring (3) and
mounting at four equi-distant points. Distance X must be
between 0.38
0.76 mm.
Tighten nut (2) fastening flange (1) to the drive output shaft
(4) to the specified torque. Then check that end play is
between 0.025
0.102 mm using a magnetic base dial gauge
(3) positioned on shaft (4).
If reading is other than specified, replace the snap ring (5,
Figure 114) with one of the correct thickness.
Extract the drive output shaft (5) complete with bearings (2
and 3) and bearing cup (1) from bearing cage (4).
Use a suitable extractor to remove bearings (2 and 3) from
the drive output shaft (5).
