What holds the chuck on the spindle besides the 33 taper and how do you remove it ?

Nothing.
Generally the JT converts to a Morse Taper.
I have a feeling this is not answering your question......?

Yes you are answering my question my drill press has the taper and a nut to hold the chuck on. ( Craftsman )
The chuck is defective and needs replaced parts for my drill press are not available wondering if another chuck without the nut would work ?

If it has a threaded collar, just unscrew the collar and it will force the chuck off the spindle taper. No collar, you will need a pair of wedges made for the puporse. There are other methods, but I would not suggest them, especially if the spindle is not hardened.

I was curious if it is a Craftsman which usually has the collar. The spindle is not hardened and easy to bend or damage.

Yes it is Craftsman Thanks everybody for your input I think I will rebuild the chuck.

The taper is supposed to do the majority of the holding on if you catch my drift.  The locking collar or nut is for added security, you could mount a chuck just to the J33 taper without the collar.

This is a link for a J33 keyless chuck over on Amazon.  Keyless chuck.  It includes a collar which hopefully will fit the thread you have.   I would do this over rebuilding the old chuck.  YMMV

Maybe not.  I've had other presses where I got the collar slack and all it did was sit on top of the chuck loose with the chuck still firmly on the taper.  One way you could try to free it would be to mount a large allen wrench in the chuck with the long end going out (short end in) and then lock the spindle so it doesn't move.  Then a whack or two with a mallet on the end of the wrench might be enough to break the friction bond and loosen the chuck. But do be careful if you bugger up the spindle, then all you have is parts machine.
