Gear puller?
Have you attempted to use a gear puller?....The manual says to heat the retainer with a heat gun to break the Loctite bond, but it seems you already have the retainer off. The next step would be to attach a universal gear puller on it and slowly tighten the bolts down until it frees itself from the shaft (magneto side flywheel). When you do this, you tighten them down pretty good, then tap on your center bolt (which is what your tightening) with a hammer. Let me say that again...."tap". Once it breaks the seal, it should just pop right off.........let me know if you get it off and if you have other questions....I've got the gear puller and it works like a charm.
