Rotate the engine until the small notch -1- on the vibration damper aligns at the left of the housing separation point -2- between the cylinder block and the guide frame. This makes it easier to install the Crankshaft Locking Pin:T40069  .

The marking on the vibration damper is only there to help. The exact "TDC" location is only reached by installing the Crankshaft Locking Pin:T40069  .

-- Install the Crankshaft Locking Pin:T40069  in the hole and tighten to 20 Nm. Rotate the crankshaft back and forth slightly to center the pin completely, if necessary.
