Harmonic Balancer - Crankshaft Pulley: Service and Repair

Vibration Damper

Special tools, testers and auxiliary items required

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

• Crankshaft Adapter (T03003)

• Locking Pin (T40069)

Lock the crankshaft for checking/adjusting the valve timing. Refer to => [ to Check/Adjust Valve Timing ] Procedures.

Note the following whenever working inside the engine compartment due to limited space:

• Route all lines and wires in their original locations.

• Ensure sufficient clearance to all moving or hot components.

Removing

- Remove the noise insulation.

- Remove the rear section of the front wheel housing liner.

- Install the crankshaft adapter (T03003) onto the vibration damper bolts.






The crankshaft adapter (T03003) can only be installed correctly in one position.

- Rotate the crankshaft in engine rotation direction - arrow - far enough until the arrow - A - on the crankshaft adapter (T03003) points downward vertically, relative to the engine axis.

This position corresponds approximately to Top Dead Center (TDC) position of the crankshaft at cylinder 5.

• With the engine removed, the TDC mark can also be seen on the vibration damper and the belt pulley side sealing flange. Notches - A and B - must align.






- Remove the plug - 1 - from the cylinder block.






- Look through the threaded hole. Make sure the hole - 2 - in the crankshaft is lined up with the threaded hole.

Use a mirror for this.

- Rotate the crankshaft slightly, if necessary.

- When the holes line up, install the locking pin (T40069) all the way into the threaded hole and tighten it to 10 Nm. Make sure the crankshaft cannot be turned.

- Remove the Air Conditioning (A/C) compressor ribbed belt. Refer to => [ Ribbed Belts ] Ribbed Belts

- Loosen the vibration damper bolts and remove the vibration damper.

• Replace the bolts

• Only use bolts with a strength category of 10.9.

• Tightening specification: 50 Nm + 90° (1/4) additional turn

After removal and installation work

- Remove the locking pin (T40069) and install the plug - 1 - to the cylinder block.






Installing

The rest of the installation follows the reverse of the removal procedures.
