Fitting cylinder head
2. Fit the gasket on the cylinder block with
the word "ALTO" facing the operator, tak-
ing care not to get the gasket or the surface
of the cylinder bock dirty or greasy. The di-
ameters of the openings shown by the ar-
rows increase from cylinders 1 to 4 so that
the engine coolant is evenly distributed
throughout the entire cylinder block.
A = exhaust side
B = inlet side
ASTADUR type cylinder head gas-
kets are fitted. On account of the
special material from which these
gaskets are made, they undergo a
polymerization process during the
operation of the engine becoming
considerably harder during usage.
In order for the polymerization proc-
ess to take place, the cylinder head
gasket must be:
- kept in its sealed nylon container;
- only taken out of its casing shortly
before fitting;
- not lubricated with oil or dirtied,
taking care that the surface of the
cylinder head and cylinder block
are clean.
3-4. Position the cylinder head and tighten
the bolts to a torque of 2 daNm follow-
ing the order illustrated.
