Abstract
A camshaft (10) is formed from a plurality of individual chill cast cams (12) and an elongated shaft (24). Each cam (12) has a hole (20) therethrough which has a groove (22) in its surface at a predetermined angular position. The shaft (24) has a plurality of cam receiving portions (24a) thereon which are spaced along the shaft and each have an outer peripheral surface (26) which is a close fit in the hole (20) in one of the cams (12). The outer peripheral surface (26) has a groove (28) therein at a predetermined angular position. The grooves (22,28) cooperate in forming a passage (30) which receives a wedge member (32) to hold the cam (12) in a fixed orientation relative to the shaft (24).
