3. Remove adapters with high voltage wires.

4. Disconnect the four-pin wiring connector from the ignition coil.

5. Disconnect the wiring connector from the Hall sensor.

Installation

10. Remove the remaining sealant from the contact surfaces of the cylinder head and camshaft housing.

11. Apply sealant to the contact surface of the camshaft housing (pic. 4.9 b).



12. Make sure that the roller rocker is in contact with the end of the valve stem 1 correctly and is fixed on the pusher 2 (pic. 4.9 in).




13. Screw in two studs (M6x70) into the cylinder head before installing the camshaft housing.

14. Carefully install the camshaft housing onto the cylinder head studs and guide pins (arrows) (pic. 4.9 g).



15. Tighten the new camshaft housing bolts (from inside to outside in a cross order). Make sure the camshaft housing is not skewed. Tightening torque: 10 Nm + 1/4 turn.
