Crankshaft Sensor Wheel, Installing

Special tools and workshop equipment required 

• Torque wrench (5-50 Nm) VAG 1331
• Locking compound D 154 100 A1

Procedure 

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

NOTE:

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 tightening that the screws heads would make contact on the crankshaft -3- and the sensor wheel would lie loosely under the screw heads.

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

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

-- Tighten all new bolts lightly by hand.

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