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 or
precision-turning. If the scores or cracks are severe than
permissible specifications, replace the flywheel.
lWhen 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’.
lDo not machine under ‘b’ value.
lWhen machining, fix the flywheel exactly not to exceed the
standard runout.
