OK you need to either to get a hub/sprocket/pully puller 2/3or 4 arm and use that, or ckeck to see if your prop bolt holes go all the way through the hub if they do get hold of at least two prefferably four bolts that are threaded full length and will go all the way through the hub and gently tighten them alternatly against the front bearing housing, if you can put something inbetween the bolt and the housing to stop any peening over of the bearing seating. Still do not know why you need to get it of though.
