• The cylinder head gasket is a part that needs to be selected for
use. Choose the appropriate gasket in the following manner.
• Measure the piston protrusion from each cylinder. (See Piston.)
• Then, from the table below, choose the cylinder head gasket
having a thickness appropriate to the average protrusion of the
pistons.
• If the cylinder head has even one cylinder that exceeds the larg-
est of the measured piston protrusions by 0.05mm or more, use
a gasket at least one size larger in thickness
(A → B, B → C).

• Identify the appropriate type of cylinder head gasket according
to the number of notches in its notched end.
• Remove oil and any other contamination from the surfaces
where sealant is to be applied.
• Apply sealant onto the surfaces of the flywheel housing and
crankcase that will be fitted together.
• Within three minutes following the sealant application, install the
cylinder head onto the crankcase, with the cylinder head gasket
in between them, using the cylinder head bolts. Take care so that
the applied sealant is not displaced during installation.
Be sure to install the gasket in the illustrated position.
CAUTION
• Do not start the engine for at least an hour after installation.
• Whenever cylinder head bolts are loosened or removed af-
ter installation, the cylinder head gasket must be replaced
and sealant reapplied.
• Tighten the cylinder head bolts to a torque of 78N.m {8kgf.m} in
the order shown in the illustration.
• Further tighten the bolts in the illustrated order as follows.
