Abstract
A method for mounting a valve seat ring on a cylinder head of an internal combustion engine includes providing a valve seat ring, which has a ring height, and which is measured along an axial direction. The valve seat ring includes a support portion made of a support material and a functional portion made of a functional material. The valve seat ring is arranged on the cylinder head and the support portion of the support material is at least partially removed, so that the ring height of the valve seat ring is reduced.
