Woo! That's just what I needed. Thanks for all the info. I just placed the order for it all on bikebandit. they had it all, including the sprocket, so I could order in one shot. I have all the necessary tools and the manuals that a previous poster linked to, so I should be good to go. I'll start the teardown next week and keep this thread up to date. If you think of anything else that I may need along the way, let me know.
