Crankshaft, Locking to Check / Adjust Valve Timing

Crankshaft, Locking to Check/Adjust Valve Timing

Special tools, testers and auxiliary items required

• Torque wrench 5-50 Nm (VAG 1331)

• Crankshaft adapter (T03003)

• Locking pin (T40069)

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

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

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





In order to be able to precisely check and adjust the 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!





• The crankshaft must not be rotated past the Top Dead Center (TDC) marking. This means the hole - 2 - in the crankshaft must not rest above the threaded opening.





If the crankshaft was rotated past the TDC marking:

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

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

If the crankshaft rests just in front of the TDC (bore in crankshaft can be seen up to 90%), the (T40069) can be installed, but with some stiffness.
