CYLINDER HEAD
INSTALLATION
Check the cylinder head cover packing (1) and spark
plug tube seal (2) for oil leaks, deterioration or damage,
and replace them if necessary.
Install the cylinder head cover packing and spark plug
tube seal to the cylinder head cover (3).
Clean the cylinder head mating surfaces with a shop
towel or equivalent material.
Apply 2.0 – 3.0 mm (0.08 – 0.12 in) bead of liquid
sealant (Threebond® 1280B or equivalent) to the chain
case mating surface (1), and 2.0 – 3.0 mm (0.08 – 0.12
in) bead of liquid sealant (Threebond® 1215 or
equivalent) to the No. 5 rocker shaft holder mating
surface (2) of the cylinder head.
• To prevent leaks, do not install the parts if 5 minutes
or more have elapsed since applying the liquid
gasket. Instead, reapply liquid gasket after removing
the old residue.
• After assembly, wait at least 30 minutes before filling
the engine with oil.
