Method for the production of a cylinder crankcase having multiple cylinder liners and short cylinder liner with a material strip affixed thereto

A method for producing, by forming techniques, an undercut profile in the outer circumferential face of cylinder liners to be cast in place in a crankcase, characterized by the introduction of a bracing inner core into the cavity of a cylinder liner, the introduction of the cylinder liner equipped with bracing inner core into a first forming die equipped on its working faces with a serrated profile, the pressing of the first forming die against the outer circumferential face of the cylinder liner, thus producing a complementary profile in the outer circumferential face, the introduction of the cylinder liner equipped with bracing inner core into a second forming die equipped on its working faces with a smooth surface, and the pressing of the second forming die against the outer circumferential face of the cylinder liner equipped with the complementary profile.
