I would just call or email Clam customer service and ask the to explain how to do it. I have never done it personally but from what I hear there is a one way bearing in the fly type reels. it turns one way freely and the other way is part of the drag system. It should be as simple as turning the bearing around so the reel turns freely and the drag works in the right direction and of course the frame of the reel will need to be turned around too.
