My experience with the solids is that they are pressed in so tight I find them impossible to remove without the aid of a machine shop. I have never been able to do it alone. One other thing, John, the solid replacement bushing is no longer available, so you will have to replace it with the split type (#B-4655). Because of the difference in the sizes of the two bushings you will also have to replace the bearing with a larger one (#B-4645). You will still be using the same size grease seal (#B-4245). What a job,huh?
