TOYOTA SUPRA 1995 Service Repair Manual

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.
