Stihl 261cm, I need some help!

If the shaft and the flywheel is all bugger up like you say you are never going to get the matting surface to hold friction. It is a tapered shaft with tight tolerance, not going to work if it is not matching taper and clean. Then you can tighten nut to proper tourqe. Those threads will only stretch so much and be worried tourqe to much you might strip them.

If you get a new flywheel, work on the shaft to match taper and get it clean.

Shaft seems fine, just the flywheel that's buggered up. I was concerned about stripping threads, anyone have torque specs for the flywheel off the top of they're head?

Edit: just found the specs, 28nm, roughly 20 ft lbs.

Get some lapping compound and put your new flywheel on and just twist it back and forth with the compound on the shaft. The clean it really really good. Should hold.

I told you use the impact!

I don't have one. I said I've got a impact driver not a impact wrench, don't know anyone that does that I could borrow from.

Gun! Ithoughtyou said you had a Dewalt 18 volt?

No, I don't have one. I'm going to get one, I have the dewalt 20v battery line for my other tools. The more I talk to y'all the more tools I realize I need.

Yup, if you like working on stuff, you need cool tools to speed things along.

OK guys, she's running right. Got the new flywheel, took @lone wolf's advice and zip it on there with my impact, only after taking @ZeroJunk's advice of putting lapping compound on it, rubbing it then cleaning it up really good. Thanks to everyone that provided input. At the end of it I can say for sure I've learned something.
Gotta get more tools Thanks again guys!
