The shop manual describes the "correct" way to repair a bike. Alas, when your bike is old and/or orphaned like mine tend to be, you find that the special tools described in the book are either no longer available or so darn expensive that you might as well just junk the bike and buy another one. Or, perhaps, the "correct" procedure requires ten people and a fully-equipped shop. Or seventeen steps that will take about eighty hours of labor, and you've got to be on your way in an hour. Fortunately, there is often a cheaper or simpler way that still works well enough, and this page contains links to a few that worked for me. Your mileage may vary, of course. I am not responsible. (Not only am I not responsible if it doesn't work for you, I'm just not responsible, period. Ask anybody who knows me.)
