Flywheel Check

1. Inspect the flywheel for:
- cracks.
- heat checks or other damage.
- machine friction surface of flywheel if scored or worn.
2. After machining
- Surface runout must not exceed 0.13 mm (0.005 inch) TIR, surface finish must be in the range of 4.0/1.3 micrometer (160/52 micro inch).
- Major diameter of dowel pin (press fit diameter) must not extend above the new surface.
- The clutch pressure plate retaining bolts must screw into the flywheel under hand torque to within 1.50 mm (0.06) of new surface.
- Flywheel with dimensions less than the charted dimensions must not be used; install new service flywheel.
