Altima V6-3.5L (VQ35DE) (2006)
Flywheel: Specifications
Tightening Torques & Sequences
FLYWHEEL RUNOUT (M/T)
NOTE:
^
This inspection is for double mass flywheel only.
^
Do not disassemble the double mass flywheel.
Flywheel Deflection
^
Measure the deflection of the flywheel contact surface to the clutch with a dial gauge.
^
Measure the runout at 210 mm (8.27 inch) diameter.
Limit: 0.45 mm (0.0177 inch) or less under no load
^
When measured value exceeds the limit, replace the flywheel with a new one.
^
Measure axial displacement at 250 mm (9.84 inch) diameter.
Limit: 1.3 mm (0.051 inch) or less under 100N (22.48 lb) force
Movement Around in Rotation Direction
Check the movement amount with the following procedure:
1. Install a bolt to clutch cover mounting hole and place a torque wrench on the extended line of the flywheel centerline.
^
Tighten the bolt at a force of 9.8 Nm (1 kg-m, 87 inch lbs.) to keep it from loosening.
2. Put a mating mark on the circumference 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 the circumference of the flywheel on the transaxle side.
Flywheel movement in rotation direction: 20.22 mm (0.796 inch) or less
^
When the measured value exceeds the standard, replace the flywheel.
