Caution! If the rockers arms are already installed in the cylinder head (Refitting the rocker arms, shims and valves), insert the camshaft (16) carefully rotating it as you go, so that the camshaft lobes do not foul the rocker arms.
Before fitting the camshaft, check the punch mark: "V" means vertical, "O" means horizontal.
Apply graphite oil to the seats of the camshaft so that it is lubricated also during the initial revs of the engine.
Insert the camshaft (16) from the left-hand side of the cylinder head.
If previously removed, relocate the spring (A) of the opening rocker arm (B).
Check the condition of the Woodruff key (15) and its groove, and install it.
