Abstract

A method for assembling a camshaft from a support shaft and components to be connected to the support shaft, the components having through-openings for receiving the support shaft. In this method, a support shaft is provided, having first diametrical enlargements in first regions, in which the components are to be secured, and second diametrical enlargements in second regions, in which the components are to be pre-positioned. A diameter (D2) in the second regions is smaller than a diameter (D1) in the first regions The support shaft is cooled and/or the components are heated up, so that the support shaft can be pushed with its first and second diametrical enlargements through the through-openings of the components.
