Cylinder head assemblies: camshafts
Refitting the camshafts
If the stud bolts (2) were removed, apply the recommended threadlocker to the short end of the stud bolts (2), i.e. the
end that is to be screwed into the cylinder head. Tighten the stud bolts (2) to a torque of 10 Nm (Min. 9 Nm - Max. 11
Nm) (Sect. 3 - 3, Engine torque settings).
Check that the camshafts (marked "VA" and "VS" for the vertical cylinder head and "OS" and "OA" for the horizontal
cylinder head) are clean and in good condition. If the camshafts are not new, use emery cloth to remove signs of wear on
the cam and support surfaces, working on a flat surface.
Lubricate with the specified lubricant (Molykote M55 Plus), the camshaft seats on both the cylinder head and the supports
(22) and (23) (green zone). Fill the reservoirs (A) with the recommended lubricant (Molykote M55 Plus).
