Caution:It is likely that the cylinder liners and pistons are manufactured Modern 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. 

Segment Characteristics:

• • Segment Diameter:Ø 58mm
  • Thickness of Upper Segments (Fire-resistant): 1.75mm
  • Thickness of Intermediate Segments (Waterproof): 2mm

It is essential to check the ring end gap of each ring before installing them on the pistons, according to the values ​​given by the manufacturer or in the supplied instructions.or the values ​​provided in the instruction manual.

During installation, the ring end gap must be evenly distributed around the piston circumference at 120°.
