– Turn the crankshaft counter-clockwise with a spanner,
using the appropriate access hole on the crankcase cover;
– Align the top dead centre notch (TDC) “A” on the flywheel
with the reference “B” on the left crankcase cover.
– Align the notches “c” of the exhaust and intake camshaft
with the plane “d” of the camshaft supports.
Align the crankshaft and camshaft references
simultaneously. It is possible to be in a situation
where the crankshaft is aligned with the references,
while the camshafts are not. In this case it is
necessary to make the crankshaft move one more
complete revolution.
– Remove the timing chain tensioner cap “3”;
– Remove the timing chain tensioner fixing screws “4”, then
remove the timing chain tensioner from the vehicle.
– Remove bolts “5” of the camshaft supports following a
crossed pattern, starting from the outside to the inside;
– Remove the camshaft supports “6” from the head.
The camshaft cap bolts must be removed evenly to
prevent damage to the cylinder head, camshafts or
camshaft caps.
