Your basket Needs to come off. Its ONE 32 mm nut. Very simple. Get an old shop rag, stuff it between the gears on the back. Bend down the tab on the lock washer thats under the big nut, undo the nut and its off. Repeat steps to put it on. Use an impact if you have one. much easier.
Your clymers explains it, but for real its very simple and quick, dont be intimidated by the nut..yes its a big one but it wont bite you
