TOYOTA SUPRA 1995 Service Repair Manual

JOINT ANGLE INSPECTION AND
ADJUSTMENT
NOTICE: When doing operations which involve the re-
moval and installation of the propeller shaft, always
check the joint. Make adjustments if necessary.
1. STABILIZE PROPELLER SHAFT AND DIFFERENTIAL
(a) Turn the propeller shaft several times by hand to stabilize the
center support bearing and flexible couplings.
(b) Using a jack, raise and lower the differential to stabilize the
differential mounting cushion.
2. CHECK JOINT ANGLE OF NO.2 JOINT AND NO.3 JOINT
(a) Using SST, measure the installation angle of the intermediate
shaft and propeller shaft.
SST 09370±50010
HINT: The SST should be directly underneath the tube.
(b) Using SST, measure the installation angle of the differential.
SST 09370±50010
HINT: Measure the installation angle by placing the SST in
the position, as shown in the illustration.
± PROPELLER SHAFTPROPELLER SHAFTPR±17

(c) Calculate the No.2 joint angle.
No.2 joint angle:
A ± B = ±1° 09' + 36'
A: Intermediate shaft installation angle
B: Propeller shaft installation angle
(d) Calculate the No.3 joint angle.
No.3 joint angle:
B ± C = 44' + 36'
B: Propeller shaft installation angle
C: Differential installation angle
If the measured angle is not within the specification, adjust
it with the center support bearing adjusting washer, differen-
tial mount upper stopper and adjusting shim. PR±18

ADJUSTMENT CHART
HOW TO READ THIS CHART
Take measurements, then calculate the No.2 and No 3 joint
angle.
Mark the calculated values on the chart and read the coordi-
nates.
Replace the adjusting washer, shim and mount upper stop-
per in accordance with the coordinates read and adjust the
joint angles.
Example
Measurements (Installation angle):
Intermediate shaft 1° 50'
Propeller shaft 2° 14'
Differential 2° 15'
Joint angle:
NO.2 1° 50' ± 2° 14' = ±24'
NO.3 2° 14' ± 2° 15' = ±1'
Adjustment:
Center support bearing
Standard parts 4 mm ± 2 mm = 2 mm
Use adjusting washers which are 2 mm (0.079 in.)
thicker.
Differential
Use adjusting shims which are 1.6 mm (0.063 in.)
thicker.
± PROPELLER SHAFTPROPELLER SHAFTPR±19

HINT:
wMaintain the same thickness for the adjusting washers
and adjusting shims on both the left and right sides.
wIf a washer, stopper and shim of the exact thickness are
not available, use the parts which are nearest in
thickness.
NOTICE: Check the joint angle once again after making
the adjustment. PR±20

PRECAUTION
1. Before working on the fuel system, disconnect the
negative (±) terminal cable from the battery.
HINT: Any diagnostic trouble code retained by the computer
will be erased when the negative (±) terminal cable is discon-
nected.
Therefore, if necessary, read the diagnosis before discon-
necting the negative (±) terminal cable from the battery.
2. Do not smoke or work near an open flame when working
on the fuel system.
3. Keep gasoline away from rubber or leather parts.
MAINTENANCE PRECAUTIONS
1. PRECAUTION WHEN CONNECTING GAUGE
(a) Use ba tte ry as th e po we r so u rce fo r th e timin g lig h t,
tachometer, etc.
(b) Connect the tester probe of a tachometer to the terminal IG

of the DLC1.
2. IN EVENT OF ENGINE MISFIRE, FOLLOWING
PRECAUTIONS SHOULD BE TAKEN
(a) Check proper connection of battery terminals, etc.
(b) Handle high±tension cords carefully.
(c) After repair work, check that the ignition coil terminals and all
other ignition system lines are reconnected securely.
(d) When cleaning the engine compartment, be especially
careful to protect the electrical system from water.
3. PRECAUTIONS WHEN HANDLING OXYGEN SENSOR
(a) Do not allow oxygen sensor to drop or hit against an object.
(b) Do not allow the sensor to come into contact with water.
± ENGINESFI SYSTEM (2JZ±GE)EG±189

IF VEHICLE IS EQUIPPED WITH MOBIL
RADIO SYSTEM (HAM, CB, ETC.)
If the vehicle is equipped with a mobile communication sys-
tem, refer to the precaution in the IN section.
AIR INDUCTION SYSTEM
1. Separation of the engine oil dipstick, oil filler cap, PCV hose,
etc. may cause the engine to run out of tune.
2. Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head will cause air suction and cause the engine to run out
of tune.
ELECTRONIC CONTROL SYSTEM
1. Before removing SFI wiring connectors, terminals, etc., first
disconnect the power by either turning the ignition switch
OFF or disconnecting the negative (±) terminal cable from the
battery.
HINT: Always check the diagnostic trouble code before dis-
connecting the negative (±) terminal cable from the battery.
2. When installing the battery, be especially careful not to
incorrectly connect the positive (+) and negative (±) cables.
3. Do not permit parts to receive a severe impact during removal
or installation. Handle all SFI parts carefully, especially the
ECM.
4. Do not be careless during troubleshooting as there are
numerous transistor circuits and even slight terminal contact
can cause further troubles.
5. Do not open the ECM cover.
6. When inspecting during rainy weather, take care to prevent
entry of water. Also, when washing the engine compartment,
prevent water from getting on the SFI parts and wiring
connectors.
7. Parts should be replaced as an assembly.
8. Care is required when pulling out and inserting wiring
connectors.
(a) Release the lock and pull out the connector, pulling on the
connectors.
(b) Fully insert the connector and check that it is locked. EG±190
