Altima V6-3.5L (VQ35) (2003)
Flex Plate: Testing and Inspection
DRIVE PLATE RUNOUT (A/T)
Runout (Total Indicator Reading):
Drive plate (A/T): less than 0.15 mm (0.0059 inch)
CAUTION:
^
The signal plate is built into the drive assembly. Be careful not to damage the signal plate, particularly the teeth.
^
Check the drive plate and signal plate for deformation or cracks.
^
Keep any magnetized objects away from the signal plate, particularly the teeth.
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 deflection at 210 mm (8.27 inch) diameter.
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 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 center line.
^
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.
