seized sprocket nut

[shermerrr]

one of the four nuts on the rear sprocket of my CB350 is seized. When trying to remove it to put on my new sprocket I stripped the nut pretty bad. Anybody have any good ideas on how to removed the stripped nut. I'm thinking about using a dremel to remove it. Anybody else done this?

HEAT, apply heat to the nut. Then while it is red grasp it with a set of good vise grips, lock them on and twist. It should come loose. Now saying that I do not know if there are rubber isolators in the hub or for that matter if the sprocket is still connected to the hub assembly. So consider what else will get hot using this method.

These work great! I use em quite a bit at work.

Thanks for the advice, guys! Unfortunately I ruined the threads of the bolt when removing the nut. I need to replace the bolt. Does anyone know if the bolts from a CB350F will work on a CB350 twin?

I'm look at these:

Should be the same.

Same thing happened to me about a week ago. I used a vice to clamp the stripped out nut then some vicegrips on the stud or either way around but it came off. The ones off ebay aren't the same from what I remember because I was looking to do the same thing when I realized how screwed I was. They don't look the same as the ebay link though iirc. Mine is a 350 twin.

Just realized that you stripped out the actual stud, if you have a twin it would be kindof hard finding new ones, I looked several places and came up with nothing. How bad are the threads?

Honda probably still make them, but,will be a different part number for newer bike
BTW, enough heat to get nut red hot will probably destroy the rubber bushing inside hub, better to remove big circlip and hold drive pin in vice (use some alloy soft jaws)
