Procedures

Crankshaft, Locking

=> [ 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 front part of the right front wheel housing liner.

- Install the (T03003) onto the bolts of the belt pulley.





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

- Rotate the crankshaft in the direction of engine rotation until the arrow - A - on the (T03003) faces downward vertically in comparison to the engine axis.

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

- Remove the locking bolt - 1 - from the rear of the cylinder block.





- Look through the threaded hole and check whether the bore - 2 - in the crankshaft aligns with the threaded hole.

Use a mirror to do so.

- Rotate the crankshaft slightly if necessary.

- If the hole and bore align, install the (T40069) completely into the threaded hole and tighten it to 10 Nm.

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





- Check whether the crankshaft can be rotated.

After Disassembly and Assembly Work

- Remove the (T40069) and install the locking bolt - 1 - to the rear of the cylinder block.





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

Tightening Specification





Locking to Check/Adjust Valve Timing

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

- Perform the same steps as for locking the crankshaft. Refer to => [ Crankshaft, Locking ] Procedures.

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





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

• Turn the crankshaft only in the direction of engine rotation - arrow -. Do not rotate the crankshaft back, not even slightly!





• Crankshaft must not be rotated out over the TDC mark. This means the bore - 2 - in the crankshaft must not stand above threaded hole.





If the crankshaft was rotated out over the TDC marking:

- Rotate the crankshaft back 45° in the opposite direction of engine rotation.

- Then rotate the crankshaft again into the TDC position in the direction of engine rotation.

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