You do not have to split the case to get to the balance dampers. You do have to remove the rotor though - and you need the rotor puller/bolt to do that. (You don't "pull" the stator - the stator is bolted to the left side engine cover and sits inside the rotor.)
It's an easy thing to do if you're going after the stator. Mine looked fine but had hardened and cracked at one point.
