Check fitted pin projection out of crankshaft
Special tools and workshop equipment required
♦ Depth gauge
Test sequence
– Use Depth gauge to check projection -a- of fitted pin, with
speed sensor wheel -1- removed.
1 - Speed sensor rotor.
2 - Securing bolt.
3 - Projection of fitted pin -3- out of crankshaft a =2.5...3.0 mm.
Removing and installing speed sensor rotor
– Replace speed sensor rotor -2- each time the bolts -1- are
loosened. Tightening torque: 10 Nm + 90°.
Note
When the bolts are tightened for the second time, the contact
point on the speed sensor rotor is sufficiently deformed to enable
the bolt head to touch -arrows- on the crankshaft -3-, thus ena‐
bling the speed sensor wheel to remain loose under the bolts.
