HELP. I’m in deep **** now!



I’m rebuilding my Excello CNC spindle. I’ve taken it down as far as I

can and have a REAL problem. I can’t get the drawbar out and that’s

preventing me from getting the spindle apart.



Here’s three pictures showing my spindle. Along side it is a donor

machine spindle shaft and quill cartridge. Not exactly the same as no

drawbar but its from another Excello

At the top of the unit there was a 7/8 hex (see wrench in pictures) so

i tried to turn it. Wouldn’t go until I used a three foot cheater bar.

Now it goes round and round fairly easy, but it wasn’t a thread.



I can see this part is attached to the top of the spline on the

spindle and must be removed to complete the disassembly.



Ideas?

Can you see the end of the drawbar inside the quill? Is there maybe some sort of snap ring inside there retaining the drawbar? Just guessing, but that's an easy place to take a look.
