MOVEMENT AMOUNT OF FLYWHEEL (M/T MODEL)
NOTE: Inspection for double mass flywheel only.
Do not disassemble double mass flywheel.
Flywheel Runout
Measure runout of flywheel contact surface to the clutch with a dial gauge.
Measure runout at ...................210 mm (8.27 inch) dia.
Standard: ..........................0.45 mm (0.0177 inch) or less
Limit: .......................1.3 mm (0.051 inch) or less
When measured value exceeds the limit, replace the flywheel with a new one.
Movement Amount in 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 to keep it from loosening at a force of 9.8 Nm (1 kg-m, 87 inch lbs.).
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 Nm (1 kg-m, 87 inch lbs.) 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 circumference of the flywheel on the transaxle side.
Standard: ......................................28.3 mm (1.114 inch) or less
When measured value is outside the standard, replace flywheel.
