The arrows on the piston pin bosses must be pointed up, or to the exhaust outlet port. • The piston boss is also stamped with the cylinder location to identify the cylinder from which the piston was removed and to assure piston will be returned to its original cylinder. • Cylinders are stamped with position markings at the intake valve side (bottom) of valve rocker arm cover flange. • Markings of any piston or cylinder must be renewed if position marks and/or arrows are not entirely legible. • Replacement piston must be marked to the corresponding cylinder it is to be used with. • Always keep piston pin with its respective piston. CAUTION When replacing damaged or worn pistons, it is important that all of the engine pistons are the same size (oversize) and same weight; all should have identical oversize and weight code markings.
