If there are some threaded holes in the rear of the motor case get two threaded bolts, 1/4 x 20 tpi should be the right size.   Most hardware stores have these in the small cardboard drawers that contain all sorts of small hardware.   Look through the threaded holes you want to use to make sure the bolt will clear any stator windings then snug down the bolts pretty good and try to unscrew the blade in the same direction it runs.    If your fan is good to you it will be very easy, if not it may require some lubrication and heat.   Use of common soft screws can result in the screw bending inside the motor and then the screw can't be withdrawn.   Get these hardened cap screws but make there the ones you get have sufficient length of threads.
