CAUTION:

Risk of damaging the engine by the timing mechanism skipping.

- Only let the engine turn in the direction of engine rotation.

TIP:

Depending on the version the arrow mark -2- may not be present. In this case position the vibration damper with the notch -1- to approximately the >>four-o'clock position<< and apply a color mark.

-- Turn the crankshaft using the Wrench - 21mm: T40263 , Adapter: T40314 and the 24 mm socket in the direction of engine rotation -arrow- until the vibration damper is at "TDC".

The notch -1- on the vibration damper must align with the arrow marking -2- on the lower timing chain cover.
The marking on the cover is located in the >>four-o'clock position<<.
The vibration damper bolts can only be loosened maximum ¹ /₂ turn at first.

-- Loosen the vibration damper bolt approximately ¹ /₂ , to do this use the Counterhold - Vibration Damper: T10355 .
