How does sb9 rear adjustable drive driven motor pulley remove?

[fgen]

Hello.
I'm trying to replace the flat belt drive pulley (cone pulley) with a v belt pulley on an sb 9.
The lathe has a rear adjustable (meaning big level to tension/slacken the belt) drive.
I have the shaft out of the drive and the pulley off but I need to put a keyway in the shaft and the large pulley on the far left of the shaft is in the way.
Is there any sane way to get this off and importantly, back on after putthing in the key way? It looks like it is maybe just pressed on - no keyways or set screw, etc.
I have the rebuild book (ILion I think) which is excellent but no mention of removal of pulley, as normally not required.

Thanks

There is a taper pin through the hub and shaft and probably a press fit as well. Might be a challenge to find the small end of the pin.

Hope this helps.

How embarrassing.
Proving to be a challenge to find either end of the pin.

Thanks,
