Crankshaft Gear/Sprocket: Service and Repair

Crankshaft Sensor Wheel, Installing

Special tools, testers and auxiliary items required

• Torque wrench (VAG 1331)

• Locking compound (D 154 100 A1)

Procedure

Make sure the crankshaft/sensor wheel contact surface is free of oil and grease.

• Sensor wheel may only be installed once, since attachment points - arrows - of the countersunk bolts - 1 - in sensor wheel - 2 - are so severely deformed after mounting the second time that bolt heads make contact on the crankshaft - 3 - and sensor wheel lies loosely under the bolt heads.





- Apply a thin coat of Locking compound (D 154 100 A1) to the contact surfaces of crankshaft and sensor wheel for additional security.

- When installing, make sure that marking -VR6- - arrow - stands at individual threaded hole.

- Tighten all new bolts lightly by hand.

- Then tighten bolt - 1 - to 10 Nm + 90° (1/4 rotation).





- Then tighten bolts - 2 - to 10 Nm + 90° (1/4 rotation).
