Using a rig just like Kiwi's, pressing in my oversize blocs was one of the most grueling physical tasks I can remember in my life. Even with a cheater bar on a long pipe wrench I was pouring sweat for, it seemed like, hours. I have to think that turning the outer sleeve down to a more conventional interferance fit, or even a small bit more, would be appropriate. By the time they were in, they weren't quite lined up at the center and I couldn't get the spindle through. I bought an expandable reamer to solve that problem.
At the time I did mine, I had no idea of the theory. I thought the idea was for the swing-arm to pivot on the spindle. I have since accepted the idea of the rubber acting as a torsion bar, as Bill has said? On the other hand, I am guessing that many or most end up rotating around the spindle. There just seems to be a fundamental flaw in the concept of expecting the inner sleeves to stay put when pressure from the outer plates against the small surface area of the inner sleeves is applied by tightening the spindle. Having said that, there are propably twenty people here, who I fully respect, that will tell me their inner sleeves never slip. Dying to here it and, thankfully, running out of battery in this here portable device.
