Xterra 2WD V6-4.0L (VQ40) (2005)
Flywheel: Specifications
FLYWHEEL DEFLECTION (M/T MODELS)
^
Measure the deflection of flywheel contact surface to clutch with a dial indicator.
^
Measure the deflection at 210 mm (8.27 inch) dia.
Standard: 0.45 mm (0.0177 inch) or less.
^
If measured value is out of the standard, replace flywheel.
CAUTION: When measuring, keep magnetic fields (such as dial indicator stand) away from signal plate of the rear end of crankshaft.
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 lbs.) 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 in Radial (Rotation) Direction
Check the movement amount of radial (rotation) direction 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 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 the dimensions of movement amounts "A" and "B" on circumference of flywheel on the transmission side.
Standard: 24 mm (0.94 inch) or less.
^
If measured value is out of the standard, replace flywheel.
