1998 200dr lower engine question
 

Hello forum, picked up a 98 suzuki 200dr few weeks ago. There was a VERY stuck valve, and when I loosened the top end of head it must have released big pressure inside, because timing chain snapped. I took of top end and did notice a very stuck valve. I have since made that right....but, replacing the timing chain is kickin my butt......I have attached a pic (flywheel?)....as far as I can tell I have to get this off to replace chain (or at least I am pretty sure)....Does the flywheel come by unscrewing or with a pully remover....hope to here from folks...thanks
