The Hyperion collet puller arrived today, it took longer to open the package then it did to pop off the collet. Tool works great I was able to just slide it behind the hub there was enough room without gridding the edges. One thing I recommend is once you put the cross bar into the threaded push bolt you put a small slice (like 1/16") of fuel tubing or a small "O" ring over the free end of the bar to prevent it from sliding out. It comes with a slide in piece that fits into a groove in the base of the tool, it seems to be the same size as the base opening, maybe you slip that down around the other half of the collet to completely encircle it? I did not do that just slipped the tool behind lined up the screw with the shaft and in half a turn pop off it came.
Crist, thanks again for recommending this tool.
Best, DennisT
