Rework flywheel


Measure test distances (a, b) for machining. If the dimension (b) is smaller than the limit value or the required stock removal at the friction surface (A) is larger than 1 mm 

*BE03.30-N-1001-03A

Replace flywheel

 If the friction surface (A) is reworked, also the mounting surface (B) must be reworked with the same dimension.
The spacer dimension (a) must be kept in each case!
Rework flywheels with scorch marks, score marks or cracks in the friction surface by grinding or precision machining.

If score marks or cracks are deeper than the permissible stock removal 

Replace flywheel

 After machining, there must not be any shrink holes or chatter marks present.

Check axial runout, flatness and peak-to-valley height of friction surface or mounting surface
