• Remove oil or any other contamination from the surfaces where
sealant is to be applied.
• Install the cylinder head gasket onto the crankcase and apply
sealant to the illustrated section of the cylinder head gasket.
• Within three minutes following the application, install the cylinder
head onto the cylinder head gasket. Take care not to spread the
sealant beyond the application areas during installation.
CAUTION
• Do not start the engine for at least an hour after installation.
• Whenever the cylinder head bolts are subsequently loos-
ened or removed, the cylinder head gasket must be re-
placed and sealant reapplied upon reassembly.
• If pistons, connecting rods or other relevant parts are re-
placed, measure to check the pistons for any change in pro-
trusion. (See “PISTON, CONNECTING ROD AND CYLINDER
LINER”.)
• Tighten the cylinder head bolts to a torque of 180 N·m {18 kgf·m}
in the order shown in the illustration.
• Install the bolts.
• Further tighten the bolts, in the order shown and as follows.
• Turn the holder of counterclockwise to pretension the inter-
nal spring.
• Set
the tool such that the rod (extension) is pressed against the
rocker shaft bracket by the force of the spring.
• Align any line on the holder scale with any line on the socket
scale. (This will be used as the reference point = 0°.)
• From the reference point, turn the socket by 90° in the direction
shown. Each division on the holder scale represents 5°.
• After tightening the cylinder head bolt within the plastic region,
make a punch mark on the bolt head to record the number of
times that they have been tightened.
CAUTION
• The bolts should be tightened within the plastic region.
Never tighten them further than the specified angle.
