The sprocket at the top is pressed on. if you are talking about this or if you are taking it out , that is , the shaft, at the bottom is a small gear. It has a clip, that is plastic, that goes into the shaft and around the gear. Remove that clip and slide the gear off, remove the screws on the plate that hold the assembly, remove the shaft through the top.
