    Hello,

    I need some help with the flywheel lock nut that won't budge. I'd like to change my cam and put the bike back together while the weather is still nice.
    I don't have the flywheel tool that youre supposed to use. Did anyone here have success with getting the nut off without it?
    My locknut is stuck so tight that putting a coin in the gears on the clutch side just squashed the coin without it holding the gears. Any help is appreciated.

    Hi,
    are you talking about the tool which holds the flywheel still while you remove the nut?
    I didn't use it; I used a (pneumatic) impact wrench and it worked.

    Yeah thats the flywheel holding tool I mentioned.

    If you did it with an impact wrench, did you do anything particular to keep the wheel and gears from spinning?

    No, I just held the flywheel with a hand, because, according to my experience, most of the times the impact wrench doesn't need the object with the nut to be very firmly still.
    You can do that in a safe way, wearing protective gloves and holding the flywheel in a way in which, if it spins, it will just rub on the palm of your (glove-protected) hand.
