Cylinder Head, Removing and Installing

Cylinder head, removing and installing

Note:
^ Replace cylinder head bolts.
^ Replace self-locking nuts and bolts when performing assembly work.
^ Replace bolts tightened by turning through a specified angle as well as oil seals and gaskets.
^ On installing reconditioned cylinder head with camshafts installed, contact surfaces between roller rocker fingers and cam surface must be lubricated after installing head.
^ The plastic pads for protection of the open valves are not to be removed until immediately prior to installing cylinder head.
^ The entire coolant is to be replaced on replacing cylinder head or cylinder head gasket.
^ Cylinder heads with cracks between valve seats or between one valve seat ring and spark plug thread can be re-used without shortening service life if cracks are only minor (max. 0.3 mm wide) or if only the first 4 turns of the spark plug threads are cracked.
