of ST33051001 and ST33061000)
ST
PD350
Note
a Securely attach puller to bearing
inner race, utilizing two grooves
in
ddferential case
b Be careful not to confuse the left
and nght hand parts
PD-5
2 Remove ring gear by loosening
ring gear bolts
Note
Loosen bolts dlagonally
3 Punch off pinion mate shaft lock
pin from ring gear side using Sold
Punch KV3
1 100300
Note Lock pin is caulked at pin hole
mouth
on differential case Do not
punch it off forcibly without
checking
how it is caulked
4 Draw out pimon mate shaft and
remove thrust block, pimon mate
gears, side gears and thrust washers
Note Put marks on gear and thrust
washer
so that they can be re-
installed in theu oripnal positions
from which they were removed
INSPECTION
Thoroughly clean all disassembled
parts, and examine them to see that
they are worn, damaged
or otherwise
fdulty and how they are affected
Repdir or replace all faulty parts,
whichever is necessary
1 Check gear teeth for scoring,
cracking or chipping, and make sure
that tooth contact pattern indicates
correct
meslung depth If any damaged
part is endent, replace parts
as re-
quired
Note. Drive pinion and drive gear are
supphed for replacement as a set,
therefore, should either part be
damaged, replace
as a set
2 Check pmion mate shaft, thrust
block, and pmion gears for scores and
signs of wear, and replace as required
Follow the same procedure for side
gears and their seats
on differential
case
3 Inspect all bearing races and
rollers for scoring, clupping or
evldence of excessive wear They
should be in tiptop condition such as
not worn and with rmrror-lke sur-
faces Replace if there
is a shadow of
doubt
on their efficiency, as an incor-
rect beanng operation may result
in
noise and gear seuure

DIFFERENTIAL CARRIER (Type R200)
4 Inspect thrust washer faces Small
damage can be corrected with sand-
paper If pinion mate to side gear
backlash
(or the clearance between
side gear and thrust washer) exceeds
the specified value, replace thrust
washers
Pinion mate-to-side gear backlash:
Less than
0 15 mm (0 0059 in)
5 Inspect carrier and differential
case for cracks or distortion If either
conmtion
1s evident, replace faulty
parts
6 As
a general rule, oil seal should
be replaced at each disassembly
ASSEMBLY AND
ADJUSTMENT
Assembly can be done in the re-
verse order of disassembly Adherence
to the following directions for ad-
justment and usage of special tools
enable to obtain a perfect differential
operation
PRECAUTIONS IN
REASSEMBLY
1 Arrange slums, washers and the
llke to install them correctly
2 Thoroughly clean the surfaces
on
which shuns, washers, bearings and
bearing retainers are installed
3 Thoroughly clean od from rmg
gear bolt and its hole and contacting
surfaces of rmg gear and differential
case with “Locktite Lacquic Prnner”
or equivalent
4 Apply gear oil when mstalling
beanngs
5 Pack recommended multi-purpose
grease mto cavity between hps when
fitting
OII seal
ASSEMBLY OF
DIFFERENTIAL GEAR CASE
1 Assemble pnnon mates, side gears,
thrust washers and thrust block in
dlfferential case
2
Fit puuon shaft to differential
case
so that it meets lock pin holes
3 Adjust side gear-to-pinion mate
backlash or adjust the clearance be-
tween the rear face of side gear and
thrust washer
If above procedure is not effective
with existing washer, try with other
washers

4 Lock pinion shaft lock pin using a
punch after it
IS secured in place
5 Apply oil to gear tooth surfaces
and thrust surfaces and check that
they turn properly
6 Apply locktng agent [Locktite
(stud lock) or equivalent] to contact-
ing surfaces of rmg gear and differen-
tial case, then place differential case
on rmg gear
7. Apply a small amount of locktng
agent (described above) to rmg gear
bolts, and mstall them
CAUTION:
a.
Use only genuine drive gear bolts.
b. Tighten bolts in criss-cross fashion
lightly tapping around bolt heads
with a hammer.

ADJUSTMENT OF SIDE
BEARING WASHERS
1 If the hypoid gear set, carrier,
differential case
or side bearing has
been replaced with new
part, adjust
the side bearing preload with adjusting
washer The required thicknesses of
the left and nght washers can be
obtained from the following formulas
T, =(A-C+D-H)xOOl +E+205
T2 =(B- D t H') x 0 01 t F+ G+ I 95
Where,
Ti Required thickness
of left side
washer (mm)
T2 Required thicknes of right side
washer
(mm)
A& B Figure marked on the gear
carrier
C & D Figure marked on the differ-
ential case
E & F These are differences in width
of left or right side bearing against
the standard width
(21 00 mm)
If bearing width is 20 82 mm, this
21 00 -2082 =O 18 (mm)
This is the difference in thickness
of side spacer against the standard
width (8
10 mm) If spacer width is
8 02 mm, this figure wdl be as
follows
H Figure marked on rmg gear
8
10 - 8 02 = 0 08 (mm)
Figures for A, B, C and D are
dimensional variations m a unit of
l/loO mm against each standard meas-
urement
To measure width of side bearing,
see differential case assembly pro-
cedure
Before calculation, deterrmne "G"
value by measurmg spacer thxkness If
spacer is deformed or scratched, re-
place
