Abstract
A method may include locating a first lobe member of a camshaft on a first shaft having an annular wall defining a first bore and a first outer radial surface. The first lobe member may include a second bore receiving the first shaft. The method may further include forcing first and second deforming members through the first bore. The first deforming member may have a first outer diameter that is greater than an initial inner diameter of the first shaft and may displace the annular wall in an outward radial direction to provide a first engagement between the first outer radial surface and the second bore. The second deforming member may have a second outer diameter that is greater than the first outer diameter and may displace the annular wall in the outward radial direction to provide a second engagement between the first outer radial surface and the second bore.
