fall between
15-18

load is inadequate shims must be with-
drawn, whereas if an excessive figure
is obtained additional shims must be
fined.
When the correct pinion pre-load is
obtained remove driving flange and

The differential assembly bearings are
now fitted without, as yet, installing
any packing shims.
A
suitable driver
such as that which is shown in Fig.

should be used for driving the bearings
on to the crown wheel carrier.

The axle bearing seats are carefully
cleaned and any excresences removed.
The differential casing is positioned
and the bearing caps, fitted with
regard to the identification markings,
are tightened down and then slack-
ened off a

turn. This will prevent
the bearings tilting but allow sideways
movement.
A
dial indicator gauge is
mounted on the axle centre cazng\ith
