Preparatory tasks

3

Move camshafts to default position.

 To do this, turn crankshaft (10) in direction of engine rotation using an open-end wrench.
Align groove (12) on crankshaft (10) with bore (13) on crankcase (11).

4

Remove screw plug (1) from crankcase (11).

5

Screw drift into bore on crankcase (11).

 Drift

Check

7

Attach adjusting tool (3) with screw (4) to the cylinder head cover (5).

 During attachment, wedge (9) on  adjustment tool (3) must engage in grooves (8) of exhaust camshaft, while pins (6) of  adjustment tool (3) must engage in bores (7) of intake-camshaft gearwheel. If  adjustment tool (3) can be attached without high force expenditure, the camshafts are in the basic position.

 Adjustment tool

*699589024000

If the adjusting tool (3) cannot be attached,



Turn crankshaft until adjustment tool (3) can be attached with ease.

 To do this, turn crankshaft only slightly either in direction of engine rotation or in opposite direction of engine rotation.

 Adjustment tool

*699589024000

If necessary in order to turn crankshaft:



remove drift again.

 Drift

If adjustment tool (3) still cannot be attached with ease after turning crankshaft (10):



Set basic position of camshafts.
