tioning the external fifth wheels of the bearings in
the relevant seats.
2. Position shim washers 1 in the relevant seats,
in order to remove the bearing clearance and to fix
clearance between the pinion and the crown gear.
3. Make sure the bearing support marks, punched
in the removal seat, are aligned with the corre-
sponding ones located on the differential support.
4. Check clearance between the pinion and the
crown gear, replace the shim washers so as to ob-
tain a 1.0 mm clearance.
5. Remove the shim washer on the opposed side
of the crown gear and, fit a shim washer with an
oversized value (incremental step of 0.1 mm.) with
an appropriate tool.
