8. REMOVE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
9. REMOVE CAMSHAFT
NOTICE: Since the thrust clearance of the camshaft is small, the camshaft must be kept level while it is being removed. If the camshaft is not kept level, the portion of the cylinder head receiving the shaft thrust may crack or be damaged, causing the camshaft to seize or break. To avoid this, the following steps should be carried out.
a. Bring the service bolt hole of the sub gear upward by turning the hexagon wrench head portion of the No. 2 camshaft with a wrench.
b. Secure the sub gear to the main gear with a service bolt.
Recommended service bolt
