well first off you heve to clamp the flywheel and wrench off that peice on the clutch slips around then after you remove that the fly wheel taps off. i usually just clamp the flywheel and tap the crank shaft from flywheel side but use a wooden mallet so you do marr the shaft but the flywheel is pressure fit so it will have to be tapped off. so just hold the flywheel with some big pliers while u turn that nut
