    NOTE: Since the thrust clearance of the camshaft is small, the camshaft must be kept level while being removed. If the camshaft is not kept level, the cylinder head or camshaft may be damaged. To avoid this, the following steps must be carried out.
    1. Align the timing marks (1 dot marks) of the camshaft drive and driven gears by turning the camshaft with a wrench.
