- NOTICE:
- As the thrust clearance of the camshaft is small, the camshaft must be kept level while it is being installed. If the camshaft is not kept level, the portion of the cylinder head which receives the shaft thrust may crack or be damaged. To avoid this, the following steps should be carried out.
- Having the crankshaft pulley at a wrong angle can cause the piston head and valve head to come into contact with each other when installing the camshaft. Be sure to set the crankshaft pulley at the correct angle as shown in the illustration.
