NOTE:

After tightening a second time, the attachment point of the countersunk screws for the sensor wheel are so deformed that the screw heads lie on the crankshaft -3- -arrows- and the sensor wheel is loose underneath the screws.

Installation of the sensor wheel is only possible in one position, the bores are offset.
