Machining of Flywheel
Notice: Flywheels which have scorch marks, scoring
or cracks in the clutch surface should be machined by
grinding or precision-turning. If the scores or cracks
are severe than permissible specifications, replace the
flywheel.
•
When machining the clutch surface ‘A’, the mounting
surface (B) for the clutch pressure plate should also
be machined in accordance with ‘A’ to keep the
distance ‘a’.
•
Do not machine under ‘b’ value.
•
When machining, fix the flywheel exactly not to
exceed the standard runout.
