• If measured value is out of the standard, replace flywheel.
Movement Amount in Radial (Rotation) Direction
Check the movement amount of radial (rot
ation) direction with the following procedure:
1. Install clutch cover bolt (1) to clutch cover mating hole, and place a torque wrench (A) on the extended line of the flywheel
(2) center line.
• Tighten bolt at a force of 9.8 N·m (1.0 kg-m, 87 in-lb) to keep itfrom 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 the dimensions of movement amounts (A) and (B) on circumference of the flywheel on the transaxle side.
• If measured value is out of the standard, replace flywheel. Limit: 33.2 mm (1.307 in) or less.
