Installation
For installation, reverse the removal procedure.
Pay attention to the following details.
Ensure dowel pins are in place.
Install new cylinder head gasket.
CAUTION: Each installation of the cylinder
head requires a new cylinder head gasket. Us-
ing a gasket twice will cause engine damage,
even if the engine had not run.
Install cylinder screws M11 no. 17. Torque
screws as per following procedure.
CAUTION: This assembly uses stretch screws.
As the screws have been stretched from the
previous installation, it is very important to
measure each screw at assembly. If screw is
out of specification, replace by a new. Failure
to replace screws and to strictly follow the
torque procedure may cause screws to loosen
and lead to engine damage.
