5.1

Remachine flywheel

Measure limits (a, b) for machining.

*BE03.30-P-1001-03A

If dimension b is less than the limit or if stock removal on clutch face (A) is greater than 1 mm (dimension a) 

Replace flywheel

 If the clutch face (A) is remachined, the mounting face (B) must also be remachined by the same size. Dimension (a) must remain the same.

 Remachine flywheels with scorch marks, scoring or cracks in the clutch face by precision-turning.

If grooves or cracks are deeper than the maximum permissible stock removal 

Replace flywheel

After machining, there must not be any shrink holes and chatter marks on the clutch face

Check radial runout of clutch face and clutch contact face

Check two-mass flywheel

 The two-mass flywheel must not be remachined.

Check axial runout. If the permissible difference is exceeded 
