That's a taper lock bushing and sheave. Whomever assembled it put it on backwards, most likely for alignment reasons. There should be two threaded holes in the face of the bushing(the inner part)(facing the generator), they are "jacking" holes. Usually one would just use two of the bolts removed but since your bolts are captured you would need two bolts the same size but short enough to fit between the face of the generator and the bushing. Screw them in and they will force the pulley off of the bushing. You don't have much room so may have to get creative with sliding washers between the bushing and pulley to work it off. It is a taper fit and would be very difficult to drive the bushing in. Usually when I come across that I just cut the pulley parallel to the shaft so it will come off of the bushing and then pry it off of the bushing. Once the pulley is off it releases the taper lock and the bushing can then be removed.
