Hi wilbur,
I can't help you much with the problem , I have an early Greenie here which has the bolt on wheels. The Anniversaries I have worked on are an absolute pig the get the wheels I have always thought that the used the same axel (taper/keyway) and just put the flange on the axel so you could unbolt the wheel to repair a puncture or replace a tyre. I assume this is how it is done so once you get the wheel off you are still going to have to get the flange off the axel. Do not hammer the axel because all you will do is damage the thread I have had to deal with that several times over the years. You may be able to get it off with a 3 jaw puller and a bit of heat. Without power to be able to work on it I think you are going to be in trouble
