Refer to "COMPONENTS " for symbol marks in the figure.

CAUTION: A high degree of precision is required for a valve on the intake side. Never remove the valve related parts unless necessary.

NOTE:

As for replacement of parts on the intake side as shown in the exploded view, replace VVEL ladder assembly & cylinder head assembly. (Only valve oil seals are replaceable as a single part.)
VVEL ladder assembly cannot be replaced as a single part, because it is machined together with cylinder head assembly.
