setting
use
a
suitable
puller
and draw
the carrier
bearings
from each side of the differential
case
Note the
adjusting shims between
the
bearings and
case
TO CLEAN
AND
INSPECT
I Wash all
components
in
a
cleaning
solvent and
blow
dry with
compressed
air
2 Check the crownwheel and
pinion
for
wear
pitting
or
damage
NOTE Crownwheel and
pinion
are
supplied
as
matched
sets
only therefore
damage
to one
item
requires
the
replacement of
both
3 Check the differential
carrier
bearings
for
wear
pitting
or
damage If
a
bearing
is
faulty
renew the
cOf lplete
bearing comprising
inner
cone
rollers and
outer cup
4
Check the
pinion
taper
bearings
and
renew as
described
in 3
5 Examine the differential
pinion
and side
gear
teeth
and
thrust faces for
wear
pitting
or
damage
Check
that
the
thmst washers
are
in
a
serviceable condition
6 Check the differential shaft for
wear
pitting
or
damage Replace
parts
listed
in 5
and 6 if
not
in
serviceable condition

TO ASSEMBLE AND ADJUST
DRIVE
PINION
Where the old
pinion
and
bearings
are
serviceable
and
the tooth
contact
turning torque and backlash checks
made
on
dismantling
are
satisfactory
then
assembly is
a
reversal of
the dismantling procedure
If
any
of the above factors proved
incorrect
on
the
check
it will be
necessary
to carry out
the
appropriate
adjustment
as
described
in
this section
This is
not
the
case
however when
a new
piniqn
and
crownwheel
is to
be installed and
or
the
bearings
renewed
Adjustment
of the
pinion position
and
bearing
pre load
then becomes essential
There
are
two methods
of
obtaining the
correct
pinion
position which
is
regulated by
the washer located between
the
xear
bearing
inner
cup and
pinion head
One
method
r
tlires
the
