Crankshaft Gear/Sprocket: Service and Repair

Crankshaft Sensor Wheel, Installing

Special tools, testers and auxiliary items required

• Torque Wrench (5-50 Nm) (V.A.G 1331)

• Liquid Locking Fluid (D 154 100 A1)

Procedure

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

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






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

- When installing, make sure that the mark VR6 - arrow - aligns with the single threaded hole.

- Tighten the new screws by hand.

- Then, tighten the screw - 1 - to 10 Nm + an additional 90° (1/4) additional turn.






- Then, tighten the screws - 2 - to 10 Nm + an additional 90° (1/4) additional turn.
