Removing Spur Gear from an old water pump

I had this old broken water pump from a VAG group engine and I decide to make something useful from the spur gear that takes motion from the timing belt. I am going to make a forth axis for cnc machines out of this spur gear and other timing gears from engines.
I used a 2 jaw bearing puller to remove it.
