Crankshaft, Assembly Overview

Install sensor wheel on crankshaft --> [ Sensor Wheel on Crankshaft, Installing ]

• Before removing crankshaft, prepare for appropriate storage, so that sensor wheel --> [ (Item 6) Sensor wheel ] does not make contact or become damaged.

• Engine is to be secured to engine and transmission holder (VAS 6095) for performing assembly work.

• When changing bearing shells ensure that bearing shells with the same color code are used.

Sensor Wheel on Crankshaft, Installing





Special tools, testers and auxiliary items required

• Torque wrench (5 to 50 Nm) (V.A.G 1331)

• Locking fluid (D 000 600 A2)

Procedure

Make sure crankshaft/sensor wheel contact surfaces are free of oil and grease.

- Apply a thin coat of locking compound (D 000 600 A2) to contact surfaces of crankshaft and sensor wheel for additional security.

- Check that when installing "VR6" - arrow - is marked at individual threaded holes.

- Tighten all new bolts by hand.

- Tighten securing bolt - 1 - to 10 Nm + 1/ 4 turn (90°).

- Tighten securing bolts - 2 - to 10 Nm + 1/ 4 turn (90°).
