I have an old craftsman drill press. Model #113.213090:

and I've noticed the chuck that I have with it really starts to slip off drill bits, even if I try to crank it tight. So anyhow I went to replace the chuck. The chuck on it has these markings on it:

Which some quick googling told me means it has a j33 taper. So i went and bought this chuck for an upgrade:

So now the trick is to get the old chuck off. Youtube videos tell me its often either a removal key or you sometimes just kinda whack it with a mallet. Per the manual for the drill, I think its the whack option:

Heres where I'm stuck:

A couple taps on each side with a mallet after opening the jaws as wide as they go and nothing is happening at all. Sure, I could whack a little harder (to the point where the whole machine would wobble) but I dont want to do any damage. Are there any tricks I dont know about? Also, do I have a compatible upgrade chuck like I think I do?

Update:

After enough ‘whacking’ (listening to the manual and comments), this whole thing fell out:

But now I have no idea how to separate that spindle (is that what it is?) from the chuck in order to attach the replacement: enter image description here

    The older it is the more taps it probably needs. It might even need good wacks before it lets go.

    If you are going to hit it harder, you could consider holding a piece of scrap wood against the chuck and hitting that. It can be hard to reliably hit something little like a chuck; at least for me.

    I was using a piece of scrap wood already. Tomorrow morning I’ll get a little harder with the taps and report back Nov 26, 2022 at 0:21

    If no screw then it hangs, but it is a taper fiction fit so is on quite tight. Usually to put them on recommended to give a couple of taps instead of just pushing them on.
