If it is necessary to renew the large taper roller
bearings, they should be pressed off the differential
housing and end
cap.
6. Wash all parts thoroughly and dry with com-
pressed air.
7. Thoroughly inspect all components for wear or
damage marks and renew any defective items. The
adjuat&g washers, excluding the dished thrust washers
behind the bevel gears, should all be flat and parallel.
Ensure that all bearing surfaces and bores are
free
from damage, pitting or burrs and that all gears are
free from damage or excessive wear.
Crown wheel and differential assembly-
To assemble
Repare the washed and inspected parts, complete
with any new or replacement parts, for assembly
which is a careful reversal of the dismantling pro-
cedure as follows
:
1. If new taper roller bearings are to be fitted, they
must be pressed squarely on to the diameters on the
end of the differential housing and end cap noting
that, the larger of the two bearings is fitted to the
housing and that both bearings are fitted correctly
against their abutment faces
(see Fig. J9).
2. If the adjusting washer positions are not known
or
if new pieces are being fitted the following precedure
is recommended for assembling the differential hous-
ing as described in Operations
3 to 6 inclusive.
3. Fit the sphed bevel pinion into the end of the
08
differential housing without an adjusting washer

behind the head.

4. Fit the trunnion pins, dished washers and bevel
gears; the long bolt and nut which connects the split
trunnion pin should
be torque tightened to between
8 lb. ft. and 10 Ib. ft. (410 kg.m. and 1,38 kg-m.).
5. Push the splined pinion gear into mesh with the
bevel gears
as far as possible and measure the distance
from the end of the differential housing to the end
face of the bevel gears.
