VERTEX Segment 39.5 mm (Manufacturer reference: 53010003950) intended for the Cross universes. A simple and targeted replacement part, this 39.5 mm segment is designed to be mounted on a compatible piston and plays a role in sealing the cylinder to ensure compression and gas evacuation.
This segment is intended for preparations and replacements during engine reconditioning where the suitable piston has a diameter of 39.5 mm. Before any intervention, check the piston/cylinder diameter and compatibility with the intended replacement piston. In case of doubt, check the dimensions and thickness of the segment to avoid excessive play or sticking under track conditions.
