One thing is that it is quite possible that you are doing something wrong in your assemly/disassembly of somehting.

I had similar situation working on a internal gear hub. At first, I thought I needed a wierd shaped thin wrench. But working on it and wrecking my brain for a while, I realized I didn't need such a wrench. It's not designed to be needed for remove. I was not doing the proper way of assembling it. Once, I figure out the proper way...the special wrench was not needed.
