350Z V6-3.5L (VQ35DE) (2006)
Flywheel: Testing and Inspection
FLYWHEEL DEFLECTION (M/T MODELS)
^
Measure the deflection of flywheel contact surface to clutch with dial indicator.
^
Measure the deflection at 210 mm (8.27 inch) dia.
Standard: 0.45 mm (0.0177 inch) or less
^
If the measured value is out of the standard, replace flywheel.
MOVEMENT AMOUNT OF FLYWHEEL (M/T MODELS)
CAUTION: Do not disassemble double mass flywheel.
Movement Amount of Thrust (Fore-and-Aft) Direction
^
Measure the movement amount of thrust (fore-and-aft) direction when 100 N (10.2 kg, 22 lb) force is added at the portion of 125 mm (4.92 inch)
radius from the center of flywheel.
Standard: 1.3 mm (0.051 inch) or less
^
If measured value is out of the standard, replace flywheel.
Movement Amount of Radial (Rotation) Direction
Check the movement amount of radial (rotation) direction as follows:
1. Install 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 Nm (1.0 kg-m, 87 inch lbs.) 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 Nm (1.0 kg-m, 87 inch lbs.) in each direction, and mark the movement amount on the mass on the transmission side.
4. Measure dimensions of movement amounts "A" and "B" on circumference of flywheel on the transmission side.
Standard: 24 mm (0.94 inch) or less
^
If the measured value is out of the standard, replace flywheel.
