use
a suitable
puller
and

from

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

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
use
