Hi again guys,

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.
