of the differential case and fit the
carrier

With the

outer
cones mated with
the
correct
inner cone
assemply
instal
the differential in the

osing
a soft faced hammer to
tap

13 Instal the carrier
bearing caps
and
nuts
according
to
the
mating
marks on the
cap

the
retaining
nuts to the
specified torque
14
Check the
crownwheel backlash
as
previously
described
in TO DISMANTLE
If
necessary adjust
the
backlash
by transferring
the
appropriate
thickness of
carrier
bearing
shims
from one side to
the other
according
to
the
requirement
15
Check the
crownwheel run
out
if
the
run
out
exceeds
specifications
remove the differential
assembly
detach the
crownwheeJ from
the
case and check
the contact
faces
of
the case and crown wheel
for
dirt
or burrs
During
assembly
ensure
that
the crownwheel is
pulled
down
squarely
on
the
case
If the
run
out still exceeds
specifications
a new crown wheel
and
pinion
set will have to
be installed
16
Carry
out
the
tooth contact
pattern
check
as
described
previously
in TO DISMANTLE Provided
pinion

backlash and
pre
loads are correct
the desired tooth
