Caution:It is probable Modern cylinder liners and pistons are equipped with a shorter skirt. Installing modern cylinder liners and pistons to replace the original kits requires no modifications.

A shorter skirt promotes better lubrication and allows for an increased crankshaft stroke to prevent the skirt from contacting the connecting rod.

Piston installation direction: An arrow drawn perpendicular to the piston axis is marked on the top of the piston. It must be oriented in the direction of engine rotation during the connecting rod's downward stroke (see manufacturer's instructions or diagram). It is essential to check the ring end gap of each piston ring before installing them on the pistons, according to the values ​​given by the manufacturer or in the supplied instructions. During installation, the ring end gap must be evenly distributed around the piston circumference at 120° intervals.

A steel collar is installed on the oil seal surface for improved sealing and reduced pulley wear.
