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 valve timing inspection/adjustment, refer to => [ Crankshaft, Locking ] Procedures.

When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:

• Route lines of all types (for example, fuel, hydraulic, Evaporative Emission (EVAP), coolant, refrigerant, brake fluid and vacuum) and electrical wiring so that the original path is followed.

• To prevent damage to the lines, make sure there is 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 the Top Dead Center (TDC) position of crankshaft at cylinder 5.

• With the engine removed, the TDC mark can also be seen on the vibration damper and sealing flange. The 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 wit 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 rotated.

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

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

• Replace the bolts

• Only use strength category 10.9 bolts.

• 50 Nm + 90° (1/4) additional turn.

After Disassembly and Assembly Work:

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






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