Here’s the problem. The lower bush isn’t big enough to push on the edge of the upper bush. It passes under the edge of the upper bush and then gets wedged underneath. It’s too big to pass through all the way. Now maybe the parts have got worn during use. Or maybe they’re this size when new. Either way, every time I’ve tried to disassemble the forks, the two bushes wedge exactly like this. Grr!
