REMOVE CAMSHAFTSNOTICE: Since the thrust clearance of the camshaft issmall, the camshaft must be kept level while it isbeing removed. If the camshaft is not kept level, theportion of the cylinder head receiving the shaft thrustmay crack or be damaged, causing the camshaft toseize or break. To avoid this, the following stepsshould be carried out.A. Remove intake camshaft(a) Set the intake camshaft so the knock pin is slightlyabove the top of the cylinder head.HINT: The above angle allows the No.1 and No.3 cylindercam lobes of the intake camshaft to push their valvelifters evenly.
