Cylinder Head Side 1-3

1. Screw in twelve M10 Torx screws evenly and tighten according to the prescribed tightening sequence -1 to 12- in 5 steps (see table).








2. Screw in and tighten four Torx screws with M6 x 30 captive washers (10.9) -1 to 4- at the chain slot. Use of a magnetic bit is recommended so that the screw to be fitted in the slot -item 4- cannot fall into the crankcase. Tightening torque: 13 Nm (9.5 ftlb.)





3. Cylinder head side 4-6 is installed in the same way as the assembly sequence for side 1-3.

Camshaft Bearing Cap Torque and Sequence

1. Fasten housing screws for the inlet and outlet camshafts and the auxiliary screw of the adjusting gauge.
2. Turn the screws further alternately by approx. 90° each until the specified tightening torque is reached. This enables the camshafts to be mounted without any distortion.





3. Tighten housing screws M6 -1 and 2-. Tightening torque: 10 Nm (7.5 ftlb.)
4. Tighten fastening screw M8 -3- for adjusting gauge -4-. -> Tightening torque: 23 Nm (17 ftlb.)
