Removal of drill chuck arbor

[redhouseluv]

Can anyone advise me on how to remove the arbor on this MT2 keyless chuck? (see photo)

I want to replace the tang type arbor with one with the drawbar type. I have given it a good spray of WD40 and left it to sit for a while. Its a good quality one even though its secondhand from eBay, so don't want to be battering it if I don't need to. I think it doesn't have a thread so in theory should a bit of heat assist, or will that damage it?

Any help greatly appreciated, thanks......

They sell special wedges for doing that, like the example below:

https://www.travers.com/catalogsearch/result/?q=chuck%20wedge

Usual disclaimer: I have no relationship with that company other than customer.  I also have not used the wedges myself.

You also could perhaps make a similar wedge yourself.

Good Luck,

Ha......that gave me an idea to use normal drift in with chuck in the vice and the arbor popped out!
