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.

• The threaded holes -arrows- in the camshafts must face upward.
