Three bolts out, then prize the spring out on each end. Lid may be stuck to the rubber and you have to put some pressure on it to pop it loose. Unless they have improved the gasket, the lid will probably not sit right when you put it all back together. New gaskets have been to big and make the lid sit up.
Forgot, there is the control rod with the keeper on it, thats fun to put back on as well. You'll see it.
