INSTALL CAMSHAFTS
NOTICE:
Since 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
receiving the shaft thrust may crack or be damaged, caus-
ing the camshaft to seize or break. To avoid this, the follow-
ing steps should be carried out.
