Removing the clutch on a 610 is a real pain. 1st take the clutch caps and the side plate off. Then take the main drive chain idler off along with the chain, remove the castle nut and bearing. Then you will be able to remove the plate on the outside of the sprocket. Then remove the sprocket and the inside plate. That should get the drive plates off. Remember, the front clutch on each side is for reverse, and the back clutch is for forward. Good Luck !!
