FLYWHEEL DEFLECTION (M/T MODELS)
^
Measure the deflection of flywheel contact surface to clutch with a dial indicator.
^
Measure the deflection at 250 mm (9.84 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 net 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: 44.3 mm (1.744 inch) or less.
^
If measured value is out of the standard, replace flywheel.
