Align the mating marks of differential cases
B and A, and
assemble the cases.
6. INSTALLATION OF THE DIFFERENTIAL PINION
MATE/5. PINION MATE WASHER
With the washer in the position shown in the figure, install
to the differential pinion shaft, and then install to differentialM.case
B.3. SELECTION OF THE THRUST WASHER (LEFT)
(1) If the differential side gear and pinion mate gear have
been replaced, select the thrust washer (left) by
following the steps below.
@ Wash the differential side gear and pinion mate gear
in unleaded gasoline to remove all oil, grease, etc.
@ Install the previously used thrust washers (being
careful the left and right ones are used at the
correct side), together with the gears, viscous unit,
pinion mate washer and pinion shaft, to differential
cases A and
B, and then, using screws, secure
them temporarily.
@ Secure the differential case assembly in a vise so
that the differential side gear (right) is facing
upward.Caution
When securing in the vise, be sure not to hold the
differential case assembly too tightly.
@I Insert a 0.03 mm LOO12 in.) feeler gauge at two
places (diagonally) between differential case
B and
the thrust washer (right).
CautionDo not insert a feeler gauge in the oil groove of
rsrdifferential case B.

If the clearance in the thrust direction of the side gear iswithin the standard value range, the backlash of the
differential side gear is normal.

SERVICE ADJUSTMENT PROCEDURES -
CHECKING COMPRESSION PRESSURENOSFFAI
(1) Before checking compression, ensure that engine oil, the
starter motor, and battery are all in good condition.
(2) Start the engine and wait until engine coolant temperature
has risen to
85-95°C (185-205°F).
(3) Stop the engine and pull the spark plug cables.
(4) Remove the spark plugs.
(5) Crank the engine to remove any foreign objects in the
cylinders.Caution
Cover the spark plug holes with shop towel, etc., in
order to keep expelled foreign objects from flying out,
and keep away from the holes. When measuring
compression with water, oil, or fuel having entered the
cylinder through a crack, etc., these will come flying
out of the spark plug hole hot and fast, so be sure to
take the proper precautions.
(6) Set the compression gauge to the spark plug hole.
(7) Holding the throttle valve full open, crank the engine and
measure compression.
Limit: Min. 920
kPa (130 psi) [250-400 rpm]
(8) Perform 6 and 7 above for all the cylinders, ensuring that
compression pressure differential for each of the cylinders
/Iis within the specified limit.
__Differential limit: Max. 100
kPa (14 psi)
(9) If a cylinder’s compression or pressure differential exceeds
the limit, add a small amount of oil through the spark plug
hole and repeat steps (6)-(8).
0If the addition of oil brings compression up, it is possiblethat there is poor contact between the piston ring and
cylinder wall.
@ If not compression does not come up, valve seizure,
poor valve seating, or a compression leak from the
gasket are all possible.

with the stabilizer bar and the propeller shaft.
Caution
1. Ensure that the propeller shaft does not bend
greatly.
2.Ensure that the liibro joint does not receive any
shock.
NOTEThe lowering of the rear suspension assembly from the
transmission jack requires three individuals due to the
amount of weight being handled (one on the differen-
tial, and one on either side of the lower arm).
