CL–14 CLUTCH – CLUTCH UNIT (2JZ–GTE) 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. Secondary Flywheel Primary Flywheel Matchmarks (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) Measure the circumferential 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. (See page EG–122) Matchmarks
