Abstract

A method of manufacturing a push rod from a length of tube having a first end and a second end. The tube is held in a first fixture and a first tool is brought into engagement with the first end while a force is applied to deform the first end into a cone. A disc is thereafter affixed to the cone through a welding process. The tube with the disc attached is moved to a second fixture and a threaded shaft is partially inserted into the tube adjacent the second end. A radial force is applied to the tube that causes the tube to be compressed into engagement with the threaded shaft. The threaded shaft is then rotated causing its translation within the tube to establish a desired length between a face on the disc and a head on the threaded shaft to complete the manufacture of the push rod.
