6. INSPECT DIAPHRAGM SPRING FOR WEAR
Using calipers, measure the diaphragm spring for depth and
width of wear.
Maximum:
A: Depth 0.6 mm (0.024 in.)
B: Width 5.0 mm (0.197 in.)
If necessary, replace the clutch cover.
7. INSPECT RELEASE BEARING
Turn the bearing by hand while applying force in the axial
direction.
HINT: The bearing is permanently lubricated and requires no
cleaning or lubrication.
If a problem is found, replace the bearing together with the
hub.
8. INSPECT FLYWHEEL DAMPER FOR GREASE LEAKAGE
If grease has sprayed onto the clutch housing, replace the fly-
wheel assembly.
9. INSPECT FLYWHEEL DAMPER ROTATIONAL
FREEPLAY
(a) Install the 2 bolts to the secondary flywheel at diametrically
opposite positions.
(b) Holding both the bolts, turn the secondary flywheel clockwise
until it stops.
(c) Put matchmarks on the primary and secondary fly±wheels 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) M e a s u r e t h e c i r c u m f e r e n t i a l length between the 2
matchmarks on the secondary flywheel.
Standard:
105 mm (4.134 in.)
(g) Repeat the preceding steps (d) to (f) 4 times and if the
measurement is greater than the maximum length replace
the flywheel assembly.

EG±338± ENGINECOOLING SYSTEM

When the negative (±) terminal cable is disconnected from
the battery, memory of the clock and audio systems will be
cancelled. So before starting work, make a record of the con-
tents memorized by the audio memory system. When work
is finished, reset the audio systems as before and adjust the
clock.
This vehicle has power tilt and power telescopic steering,
power seat, power outside rear view mirror and power shoul-
der belt anchorage, which are all equipped with memory
function, it is not possible to make a record of the memory
contents. So when the work is finished, therefore it will be
necessary to explain this fact to the customer, and ask the
customer to adjust the features and reset the memory.
To avoid erasing the memory of each memory system, never
use a back±up power supply from outside the vehicle.
3. Even in cases of a minor collision where the SRS does not
deploy, the steering wheel pad, front passenger airbag
assembly and front airbag sensors should be inspected (See
pages RS±10, 20, 30).
4. Never use SRS parts from another vehicle. When replacing
parts, replace them with new parts.
5. Before repairs, remove the airbag sensors if shocks are likely
to be applied to the sensors during repairs.
6. Never disassemble and repair the front airbag sensors,
center airbag sensor assembly, steering wheel pad or front
passenger airbag assembly in order to reuse it.
7. If the front airbag sensors, center airbag sensor assembly,
steering wheel pad, front passenger airbag assembly or seat
belt pretensioners have been dropped, or if there are cracks,
dents or other defects in the case, bracket or connector,
replace them with new ones.
8. Do not expose the front airbag sensors, center airbag sensor
assembly, steering wheel pad, front passenger airbag
assembly or seat belt pretensioners directly to hot air or
flames.
9. Use a volt/ohmmeter with high impedance (10 k
/V
minimum) for troubleshooting of the electrical circuit.
10. Information labels are attached to the periphery of the SRS
components. Follow the instructions on the notices.
11. After work on the supplemental restraint system is
completed, perform the SRS warning light check (See page
RS±44).

5. INSPECT VALVE CLEARANCE
(a) Check only those valves indicated in the illustration.
wUsing a feeler gauge, measure the clearance between

are out of specification. They will be used later to
determine the required replacement adjusting shim.
