Procedures

Crankshaft, Locking

=> [ to Check/Adjust Valve Timing ]

Special tools, testers and auxiliary items required

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

• Crankshaft Adapter (T03003)

• Locking Pin (T40069)

Procedure

- Remove the noise insulation.

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

- Install the crankshaft adapter (T03003) to 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) of the crankshaft for cylinder 5.

• With the engine removed, the TDC mark can 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 rear of 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.

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






- Make sure the crankshaft cannot be turned.

After Removal and Installation 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 procedure.

Tightening Specifications






to Check/Adjust Valve Timing

- Remove the cylinder head cover. Refer to => [ Cylinder Head Cover ] Cylinder Head Cover.

- Perform the steps in "Crankshaft, Locking". Refer to => [ Crankshaft, Locking ] Procedures.

• If the camshaft threaded holes - arrows - do not point upward, the crankshaft must be rotated one rotation (360°) in engine rotation direction.






In order to be able to precisely check and adjust the valve timing, always note the following:

• Rotate the crankshaft only in engine rotation direction - arrow -. Do not rotate the crankshaft back.






• The crankshaft should not be rotated past the Top Dead Center (TDC) mark. This means the bore - 2 - in the crankshaft must not be above the threaded opening in the cylinder block.






If the crankshaft was rotated past the TDC mark:

- Then, rotate the crankshaft back 45° opposite the engine rotation direction.

- Then, rotate the crankshaft forward again in engine rotation direction to the TDC position.

When the crankshaft is positioned slightly in front of the TDC position (hole in crankshaft is 90% visible), the locking pin (T40069) can be installed, although slightly more difficult.
