OK, here's a case where using the search function actually leaves me more confused than before.
A friend has a 1979 750 with the typical charging problem. He diagnosed a bum stator & purchased a replacement from Electrosport. Installed it. No output (or not much). He contacts Electrosport, who tell him that he needs a different rotor. He needs a rotor from a GS850, and the original 750 rotor won't work with that stator.
OK, that's new to me, but it's been a while. He found a used GS850 rotor and is ready to install it.
The question is: How to get the existing rotor off? He's having problems. He got the bolt out, and has tried heat & hammering (ouch!) without success. I've read about pullers, including this item:

I just can't picture how this simple threaded item is going to apply outward force on that rotor, which is no doubt held onto its tapered crank end by some type of locker / locktite. The more threads I read about rotor removal, the more confusing it gets. What's pressing on what?? Do I thread this in, torque to 50 ft-lbs max and then nail the end with a hammer? All that will do is press the crank inward against its thrust surface.
I'm trying to advise the guy by phone / email. Not sure what to tell him. Any clarification of what's going on here will be appreciated!
