Kit of 4 liner base copper seals - Ø 62.5mm thickness 1mm

The sets are supplied with the following components:

• Liners (x4)
• Pistons (x4)
• Rings (x12)
• Pin (x4)
• Circle clips (x8)

Dimensions of the different parts:

• • Liner bore diameter: Ø 58mm
  • Liner flange or top diameter (D): Ø 73mm
  • Liner base diameter (A): Ø 62.50mm
  • Overall height including skirts of the sleeves (C): 126mm
  • Height from the top of the sleeve to the base gasket area (E): 112.80mm
  • Shaft dimensions: Ø 14x50mm (Cirlip-free mounting)
  • Segment thickness: 1.75mm / 2mm / 3.5mm (Fireproof/Sealing/Scraper)
  • Base gasket type: Copper gasket

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.
