Abstract
A camshaft may include a first shaft, a first lobe member, and a second lobe member. The first shaft may include an annular wall defining a first bore. The wall may include a first portion having a first radial outer surface and a second portion having a second radial outer surface that is radially offset relative to the first radial outer surface. The first lobe member may define a second bore having the first portion of the first shaft located therein and frictionally engaged with the first shaft for rotation with the first shaft. The second lobe member may define a third bore having the second portion of the first shaft located therein. The second lobe member may be rotatably disposed on the second portion of the first shaft.
