Note:
Tightening torque 1) Replace bolts 2) 90 corresponds to a quarter turn Fig. 1 Removing and installing sensor wheelAlways replace sensor wheel -2- if securing bolts -1- have been
loosened.. If the securing bolts are tightened a second time, the seats for the
countersunk bolt heads in the sensor wheel will be distorted to such
an extent that the bolt heads will come into direct contact with the
crankshaft -3- (-arrows-) and the sensor wheel will only fit loosely
under the bolts. The mounting holes are asymmetrically spaced, so it is only possible
to install the sensor wheel in one position.
