there is a trick that might get the hub apart easier, and you can field test the idea.
heat the hub/shaft junction area, get it a little red if you can.
then push an ordinary taper candle into the junction of the hot shaft and the hub.
the candle will melt and wick into the joint and help remove the friction forces
holding the hub in place. get plenty of wax all around that large surface area.
then use whatever puller you have and see if you get joy. don't burn yourself.
it worked for me to safely remove without damage a large pulley on a toro
snowblower auger section that you could not get an ordinary puller on.
i saved $80.00 by not destroying the large diameter pulley. it might help
you? it's worth a try.
good luck, bill
