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
Pinion mate gear-to-side gear
backlash
Less than 0 15 mm (0 0059 in)

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
DRIVE PINION PRELOAD
Adjust dnve pinion preload with
spacer and washer between front and
rear bearing inner races, regardless of
thickness of pinion height adjusting

This adjustment must be carried
out without

6 Measure ring gear-to-drive pinion
backlash with a dial indicator
If it IS below the specified value,
replace left washer with a thinner one
and right washer with
a thicker one If
it
is over it, replace left washer with a
ttucker one and right washer with a
thinner one
Note To maintain correct preload at
all tunes, do not change total thick-
ness
of washers

Incidentally a decrease or increase
in thickness
of washers causes change
in ring gear-to-pinion ba( klash
Thus, check for proprr backldsh

7 Check and adjust the tooth con.
tact pattern
of ring gear and drive
pinion
(I) Thoroughly clean ring and drive
pinion gear teeth
(2) Paint ring gear teeth lightly and
evenly with a mixture of powdered
ferric oxide and oil of a suitable con-
sistency to produce a contact pattern
(3) Rotate pinion through several
revolutions in the forward and reverse
direLtion until a definite contact pat-
tern is developed
on ring gear
(4) If contact pattern is incorrect,
readjust thickness
of adjusting washer
Be sure to completely wipe off red
lead upon completion
of adjustment
(5) Incorrect teeth contact pattern
'an be adjusted in the following
manner
Contact pattern
a Heel contact
To correct, increase thickness of
pinion height adjusting washer in order
to bring drive pinion close to ring gear
PO193
b Toecontact
To correct, reduce thickness of
pinion height adjusting washer in order
to make drive pinion move away from
ring gear
