How do I take apart this GMN TSI 60 x 250 left-handed spindle?
The spindle came with some other things that I got recently. The tool interface taper on the left is damaged (crash?) so I was about to throw it away when I noticed that in the box next to it was a brand new shaft. So I'd like to try and disassemble it, and move the bearings to the new shaft. How do I take it apart? I can easily remove the two rings on the right hand side of the diagram above (both are a right hand thread). This
exposes the right-hand bearing above. What's next?
(I realize that spindle bearings need great care and will try hard to apply forces in ways that don't put stress on the bearing balls or races. But the alternative is to throw it in the trash now, so I don't have a great deal to lose. I did successfully remove, clean, regrease and re-install the spindle bearings on my Logan lathe some years ago.)
