8. INSPECT FLYWHEEL DAMPER FOR GREASE LEAK-
AGE
If grease has sprayed onto the clutch housing, replace the fly-
wheel assembly.
9. INSPECT FLYWHEEL DAMPER ROTATIONAL FREE-
PLAY
(a) Install the 2 bolts to the secondary flywheel at diametrical-
ly opposite positions.
(b) Holding both the bolts, and turn the secondary flywheel
clockwise until it stops.
(c) Put matchmarks on the primary and secondary flywheels
at this position.
(d) Then rotate the primary flywheel counterclockwise by
hand until it stops.
(e) Put matchmarks on the primary flywheel at this position.
(f) Measure the circumferential length between the 2 match-
marks on the secondary flywheel.
Standard: 105 mm (4.134 in.)
(g) Repeat the previous steps (d) to (f) 4 times and if the mea-
surement is greater than the maximum length replace the
flywheel assembly (See page EM-88).

FOR ALL OF VEHICLES
PRECAUTION
1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG
(a) The TOYOTA SUPRA is equipped with an SRS (Supple-
mental Restraint System), such as the driver airbag, front
passenger airbag.
Failure to carry out service operations in the correct se-
quence could cause the supplemental restraint system to
unexpectedly deploy during servicing, possibly leading to
a serious accident.
Further, if a mistake is made in servicing the supplemental
restraint system, it is possible the SRS may fail to operate
when required. Before servicing (including removal or
installation of parts, inspection or replacement), be sure
to read the following items carefully, then follow the cor-
rect procedure described in this manual.
(b) GENERAL NOTICE
(1) Malfunction symptoms of the supplemental re-
straint system are difficult to confirm, so the diag-
nostic trouble codes become the most important
source of information when troubleshooting. When
troubleshooting the supplemental restraint system,
always inspect the diagnostic trouble codes before
disconnecting the battery (See page DI-555).
(2) Work must be started after 90 seconds from the
time the ignition switch is turned to the ºLOCKº posi-
tion and the negative (-) terminal cable is discon-
nected from the battery.
(The supplemental restraint system is equipped
with a back-up power source so that if work is
started within 90 seconds of disconnecting the neg-
ative (-) terminal cable from the battery, the SRS
may deploy.)
When the negative (-) terminal cable is discon-
nected from the battery, memory of the clock and
audio systems will be cancelled. So before starting
work, make a record of the contents memorized by
the audio memory system. Then when work is fin-
ished, reset the clock and audio systems as before.
To avoid erasing the memory of each memory sys-
tem, never use a back-up power supply from out-
side the vehicle.

2) Cornering
Supposing that the differential case is not moving, rotating the left side gear counterclockwise, causes planet gear
A (which meshes with the left side gear) to rotate clockwise.
Furthermore, planet gear B, which is paired with planet gear A, rotates counterclockwise, causing the right side gear
(which meshes with planet gear B) to rotate clockwise.
Therefore the left and right side gears rotate in the opposite direction each other, thus accomplishing a motion
differential.
3) Limited Slip Differential Operation
Limited slip is accomplished primarily b the friction that is generated between the planet gear's tooth tips and the
differential case's inner wall, and the friction that is generated between the side gear end face and the thrust washer.
The principle of limited slip enables the resultant reaction force F1 (which is created by the meshing reaction of the
planet gear and the side gear and the meshing reaction of the planet gears themselves) to push the planet gear in the
direction of the differential case in proportion to the input torque.
Due to the reaction force F1, the friction force u F2 (which is generated between the side gear end face and the thrust
washer) applies a force to cancel out the rotational difference between the side gears themselves as well as between
the side gear and the differential case.

5. INSPECT FUEL RECEIVER GAUGE OPERATION
(a) Disconnect the connector from the sender gauge assem-
bly.
(b) Turn the ignition switch ON, check that the receiver gauge
needle indicates EMPTY.
(c) Connect terminals 2 and 3 on the wire harness side con-
nector through a 3.4 W test bulb.
(d) Turn the ignition switch ON, and check that the bulb lights
up and that receiver gauge needle moves toward the full
side.
HINT:
Because of the silicon oil in the gauge, it will take a short time
for the needle to stabilize.
If operation is not as specified, inspect the receiver gauge resis-
tance.
