not as long as you use the correct puller.

someone told me that you would mess up the timing if you tried it

if you do not reinstall it right the timing may be off.

Remove the flywheel nut using an impact or flywheel holding tool and wrench. Its a 17mm. Then remove the collar inside. Install the flywheel removing tool and use it to remove the flywheel. When you reinstall the flywheel be sure the keyway is lined up properly and your timming will be correct. Reinstall the collar and nut to 58lbs.<double check tourq spec but I think that's right..

^^^^^^^Nearly right just wipe the left side of the 8 away and it will read 53 ft lb or 73 Nm

Manual says 58 ft lbs

Matter of interest which manual do you have?

The info I supplied comes from the "Yamaha" YFS200 (U-A) Yamaha service manual printed in the US.

Are there other manuals out there which are stating different specs?

It's not super critical on the torque you just don't want it to come loose.
I've been using an impact gun to do it for 20+ years.

I just read it again and must have been tired'er than i thought the night i did my gf's because i went 58ft lbs.

I stand corrected its 53.Well with the red lock tight and the 5 extra pounds it shouldnt come loose right.lol

Not always the case, if the flywheel has spun and damaged the tapers, Ihave known them to spin again even with those extra lbs added!

if you got an impact gun, i just go brrrrr a little good to go.

Dont go overboard though the thread on the crankshaft aint really that big.

I believe the scientific or technical term for the sound is tat tat tat lol
but really 1 1/2 - 2 seconds is all you need on the impact wrench to make sure it isn't coming off.
