If the position of the camshafts is incorrect or the groove in the inlet camshaft does not face outward, remove fixing pin of belt pulley and turn crankshaft a further 360° clockwise.
Then position or fix the fixing pin in the bore (1 TDC) and the fixing bore in the crankcase again.
- Check the position of the groove again.
- If the allocation is correct, at the same time, the narrow segment of the exhaust camshaft on the opposite side must face the cylinder head cover.

- Position special tool, adjustment device 9612/9, on the cylinder head and fasten with a hexagon-head bolt M8 x 30.
NOTE: Do not use force when positioning the special tool. It should be possible to fit the special tool and hexagon-head bolt with ease.
