TO REPLACE

SECTION Reverse removal operations ( Section 105 ) .
107 The clearance between the end of each axle shaft and the corresponding

.
side of the pinion spacer when assembled should not exceed 075”. If this
clearance is greater turn the spacer through 90° and check the clearance and if
necessary machine the faces of the spacer to give a working clearance between
the ends of the axle shafts, which is all that is necessary. If, however, the clearance
is excessive after turning the spacer it should be replaced.

DIFFERENTIAL GEAR — TO REMOVE
( See Figure 5 )

SECTION – Remove axle shafts ( Section 105 ).
108 – Cut the locking wire from the differential carrier bearing cap bolts ‘G’.

Remove the bolts and the bearing caps and the whole differential gear
complete with crown wheel can then be lifted out.

INSPECTION

SECTION Examine the differential carrier ball bearings. If any radial play is evident,
109 these should be replaced. The bearings are of the double purpose type, and

it is essential that they are fitted to the differential carrier, so that the side
marked ‘THRUST’ on the inner race is against the carrier.

TO FIT NEW CROWN WHEEL

SECTION – Remove differential gear ( Section 108 ) .
110 – Remove crown wheel from differential case.

– Fit new crown wheel and check with indicator.

As the crown wheel is ultimately riveted in position, it will be necessary
to bolt it in position temporarily for the purpose of testing for truth. It
.
is essential that the crown wheel should not run more than 003” out of
truth, either on its outside edge or on the tooth side. If on trying the
.
crown wheel it is found to be running more than 003” out of truth,
change its position relative to the rivet holes in the differential case and
check again. For the purpose of testing the crown wheel for truth, the
differential case with crown wheel and bearings fitted can be assembled
in its carrier or tried on ‘V’ blocks. An indicator attached to a scribing
block, brought to bear on the part of the crown wheel under examination,
may prove it necessary to true up the face of the differential carrier
before an accurate setting can be obtained. This may be carried out on a
lathe, or the high places scraped down by hand.

The crown wheel having been bolted in position and correctly trued
up, should finally be riveted on. Great care and judgment must be used
