Checking projection of fit pin from crankshaft
Special tools and workshop equipment required
t  Depth gauge
–  Use depth gauge to inspect projection -a- of dowel pin when pulse rotor -1- is removed.
1 - Pulse rotor
2 - Fixing screw
3 - Projection of the dowel pin -3- from crankshaft a = 2.5...3.0 mm

Removing and installing pulse rotor for engine speed sender
–  Replace pulse rotor -2- and bolts -1- each time they are slackened.
  Note
t  After the second tightening of the bolts, the fixing points in the pulse rotor -2- are already so deformed that the screw heads -1- are positioned on the crankshaft -3--arrows- and the pulse rotor remains loose.
t  Assembly only possible in one position - holes offset.
