NOTE:

After tightening a second time, the attachment point of the countersunk screws of 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 sensor wheel is only possible in one position - the bores are offset.

For the correct tightening specifications, refer to CRANKSHAFT OVERVIEW .
