• Loosen the camshaft journal cap bolts in several two-turn passes in the sequence shown.

• Remove the bolts.

• Remove the caps.

Caution

• If the camshaft and valve tappets are to be reused, mark the location of the valve tappets to make sure that they are assembled in their original positions.

22. Remove the valve tappets from the cylinder head.

23. Remove the inner timing belt cover.

24. Remove the generator.
