the hub is on a taperd shaft,you need a puller that has holes in it to match the holes in the hub.i use a prop hole drilling jig that has a center hole tap for treads and just use your prop bolts and screw it to your hub and use the center screw to pull off the hub.it will take a little bit of pressure to get it loose from the taperd shaft,don't use any heat on the hub,that weakens the magnet in the prop hub.
