Lift the chain again and insert the intake camshaft
placing the chain on the gearwheel. Place the shaft
so that the cams face upwards according to the ap-
proximate direction D and the references E carved
on the gear are horizontal.
Position the bearing in the same way as for the
exhaust camshaft.
Holding the camshaft still with one hand, insert an
aluminium cylinder F in the housing of the hydrau-
lic tensioner as far as needed to be able to push
the movable guide against the timing chain. Make
sure that the notches engraved on the two wheels
are aligned one with the other. Is so, the phasing is
correct. If not, release the cylinder F, lift the timing
chain so that the gearwheels disengage allowing
the needed rotation to obtain correct phasing.
Having checked phasing, extract the cylinder F.
