I agree Al. If the spline end is larger than the inside diameter of the bearing race then the spacer can not be part of the shaft. Otherwise you can't put it together in the first place. The spacer may be a very tight fit but it can not be part of the shaft. It has to come off. I would use the bearing puller and pull on the bearing and spacer together towards the quill shaft end.
On the 10ER the shaft is solid. The bearing on the spline end is installed and removed from that end. The bearing inner races is slightly larger than the splined portion of the shaft.
