I have a new replacement 28 tooth back gear to replace one with a broken tooth. Head stock is disassembled and I've reached the point for removing the old gear and installing the new piece. Problem - the old gear will not come free of the shaft. Plan view drawings of the assembly show the gear installed against a shoulder on the shaft and held in place with a woodruff key. I see no reason why a gear would have been pressed on such an assembly but I've been wrong before so I may not fully understand the assembly process. Regardless of that fact, capturing the shaft with the gear against resistance and using a soft mallet on the end of the shaft has proven unsuccessful. I am not convinced that heating the assembly is a good idea because the shaft contains a bronze bushing - would not want to damage that.
I don't own a hydraulic press. Anyone have an idea????
