MACHINING OF FLYWHEEL
1 Flywheel
Machining of Flywheel Notice Flywheels which have scorch marks, scoring or cracks in the clutch surface should be machined by grinding orprecision-turning. If the scores or cracks are severe thanpermissible 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.
