The invention relates to a method for permanently fastening at least one cam on a cam carrier, comprising at least the following method steps: a) positioning the at least one cam on the cam carrier ina predetermined axial and angular position in such a way that the cam carrier extends at least in certain portions through a through-hole in the cam, wherein an end face of the cam carrier is in linewith an end face of the cam, b) arranging the cam segment formed by the cam carrier and the at least one cam in a mounting device; c) deforming the cam carrier in such a way that the at least one camis secured on the cam carrier at least in a positively and/or non-positively locking manner against movement in the axial direction, wherein a deforming tool of the mounting device is adjusted in theaxial direction onto the end face of the cam carrier, and the cam carrier is deformed in such a way that material of the cam carrier is forced outwards in a radial direction against the cam that hasbeen placed on.
