NOTE:

Clean the backside of the bearing and the bearing surface of the
cylinder head and prevent oil from adhering to them.

NOTE:

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, causing the camshaft to seize or break. To avoid this, the
following steps should be carried out.
