Advice?
Try to heat just the taper lock hub with a torch to expand it and break the rust lock.

Are any of those holes threaded? If so, insert a bolt or bolts, and use them to push it off.
Lubrication is always better than dry. Automatic trans fluid works good in that situation.

I'd let it soak for a while. TF or penetrating oil....
Then a hard rap on the puller shaft after it's tightened up.
Then some heat as suggested above if that fails.

Cut a block of scrap wood that will slide under the hub and support it. With the block in place, tap a small cold chisel into the slot in the hub, rotate the hub and repeat in the other slot. Might have to do this a couple times on each side. Penetrating oil into the slots.

Bad experiences come from poor decisions. So do good stories.

Soak it with "Kroil" or as one of my maintenance men called it 'Panther pee" Best I have ever used.

A wise man once asked me, "are you sure it is supposed to come off of there?"
