So you are trying to remove the flywheel or the flywheel nut? If you have removed the flywheel nut you will need to use a flywheel remover to pop the flywheel loose from the flywheel colet.

If you are trying to remove the flywheel nut, then you will need to heat the nut like the others have suggested. We recommend using a heat gun to heat the nut and melt the loctite. Once you have done this you will be able to remove the flywheel using the flywheel puller.
