The plot thickens. I was able to get the bearings out by sticking the cassettes in a vice and using a hammer handle to force them to twist. It took a fair bit of doing. I purchased new bearings and when I went to put them in discovered they’re just as tight. I don’t mean a bit snug I mean impossible to twist into place by hand. This suggests to me that the cassettes are deformed, possibly overtightened at some point. So my question:
These are aluminum cassettes. This is where the pinch bolt goes through. Can anyone think of a way to force it to spread back out? I’ve put a nut in there on the pinch bolt and attempted to loosen the nut on the bolt but that just tries to stretch the bolt.
