CYLINDER HEAD OVERHAUL
Main operation
Before removing cylinder head, check hydraulic tightness using
specific tool; in case of leaks not caused by core plugs or
threaded plugs, replace cylinder head.
NOTE When replacing the cylinder head, it is supplied
as a spare part with a threaded plug, which must
be removed during assembly.
NOTE In case of plugs removal/replacement, when
assembling apply sealant Loctite 121078 on the
plugs.
Valve removal
NOTE Before removing cylinder head valves, number
them so that when they are refitted, if not
overhauled or replaced, they are refitted in the
same positions as when they where removed.
Intake valves are different form exhaust valves
in that they have a notch placed at valve head
centre.
