I got my dampener off and noticed my hub was round not the 3 pronged type. Anyone else ever see this and does it come off the same as the 3 prong.

 

It may be a aftermarket one. But Pics would help.

 

Prob an aftermarket piece. I had to replace mine when I bent the 3 prongs trying to remove it the wrong way - DON't ask. Decided to replace it with this unit from jegs as when I had my motor built a few years back my builder keyed my hub and I wanted to retain that without having another stock hub rekeyed.
