CAUTION:
Be careful not to damage contact surface for the clutch disc
of the flywheel.
NOTE:
The flywheels, two block construction, allows movement in
response to transmission side pressure, or when twisted in its
rotational direction. Therefore, some amount of noise is normal.

MOVEMENT AMOUNT OF FLYWHEEL (M/T MODELS)
NOTE:
●Inspection for double mass flywheel only.
●Do not disassembly double mass flywheel.
Flywheel Deflection
●Measure deflection of flywheel contact surface to the clutch with a dial gauge.
●Measure deflection at 210 mm (8.27 in) dia.
●When measured value exceeds the limit, replace it with a new
one.
Movement Amount in Radial (rotation) Direction
Check the movement amount in the following procedure.
1. Install a bolt to clutch cover mounting hole, and place a torque wrench on the extended line of the flywheel
center line.
●Tighten bolt at a force of 9.8 N·m (1.0 kg-m, 87 in-lb) to keep it from loosening.
2. Put a mating mark on circumferences of the two flywheel
masses without applying any load (Measurement standard
points).
3. Apply a force of 9.8 N·m (1.0 kg-m, 87 in-lb) in each direction,
and mark the movement amount on the mass on the transaxle
side.
4. Measure dimensions of movement amounts A and B on circum-
ference of the flywheel on the transaxle side.
●When measured value is outside the standard, replace fly-
wheel.Standard : 0.45 mm (0.0177 in) or less.
Limit : 1.3 mm (0.051 in) or less.
