How To Remove A Flywheel In A Stihl Chainsaw - Easy... 

DON'T EVER DO THIS! You will ruin the end of the crankshaft! Either use a brass punch or put the flywheel nut back on about half way and hit that. DO NOT hit the end of the crankshaft directly with a steel bolt or punch or the hammer directly!

That's how to damage the end of the crankshaft !!

Leave the nut on the shaft & undo it say 1 1/2 turns. Then but it. Doing what you did will & can damage the shaft & thread

I used a Brass Drift and Shazam! It worked, Thank you!

NO! You'll mushroon the crank end, or break it and be very angry! A plastic, rewhide, copper, brass, a soft hammer. Give it a tap or three and she'll come off. Remember your hitting the crank, go easy! No metal tools on the crankshaft!

Is there a woodruff key or is it machined into the flywheel?

An air impact tool applied to the shaft will pop it off instantly with no possibility of damage.

Is the nut on astilh to 360 as concrete cut off saw reverse thread

Did not work for me :/ Edit: it did work! I beat that bolt until it was bent and then it finally came off. Thank you!

Same procedure as a blower?

really easy way is to remove the chain cover,and flywheel nut then using a copper hammer give the crank a sharp tap the shock loosens the flywheel and that's it.

Never, never hit the crankshaft with a hammer like you showed your chance to destroy your bearing and seals of the cranksgaft are 99% !!

Thanks

how do you tighten that flywheel up? my problem is the flywheel moves around inside, grab hold of it and it moves back and forth.

Doesn't that mess with the timing on the coil?

No mention of a keyway. Is there not one?
