Patent ID: 7966983

Claim:
A method comprising: locating a first lobe member of a camshaft on a first shaft, the first shaft including an annular wall that defines a first bore, the annular wall including a first portion having first radial inner and outer surfaces axially aligned with the first lobe member and a second portion having second radial inner and outer surfaces, the locating including the first portion of the first shaft being located within a second bore of the first lobe member; locating a second lobe member on the first shaft including the second portion of the first shaft being located within a third bore of the second lobe member and the second radial inner and outer surfaces being axially aligned with the second lobe member; applying an outward radial force from within the first bore that displaces the first radial inner surface radially outwardly relative to the second radial inner surface and displaces the first radial outer surface radially outwardly relative to the second radial outer surface; and locating a second shaft within the first bore of the first shaft after the applying and fixing the second lobe member for rotation with the second shaft, the first lobe member being fixed for rotation with the first shaft after the applying.
