      Information 

      • Check that the through-bores on the hub of the flywheel are flush with the screw heads. 
      • Screw heads can damage the flywheel when unscrewing them if the bores are not flush. 
      • A damaged flywheel must not be installed! 
2. Loosen and unscrew ten screws (multiple-tooth, a/f 12, M10 x 29) on the flywheel. Carefully remove the flywheel (it is quite heavy - so be careful).
   1. 2.1. The screws are micro-self-locking and must be replaced! 
   2. 2.2. Remove adhesive residues from the threaded bores and clean with brake cleaner.

      Allow a drying time of at least 10 minutes!
