Individually produced cams and journals are fastened to a hollow tube to form a camshaft by outwordly deforming the tube with a lost mandrel which is left in the tube to form a seal.

Camshaft manufacture

A camshaft assembly is made by inserting a hollow tube into cams and journals in close fitting relationship. A plug is forced through the tube to a predetermined position. The cams and journals have circular shaped openings with circumferentially spaced apart axially extending grooves. The plug has circumferentially spaced apart protrusions which expand circumferentially spaced apart portions of the tube into the circumferentially spaced apart grooves in the cams and journals.
