The CD Rom is great. It has all you need and more. Complete maintenance of course, but also all schematics, with pictures, (scanned in, but they are there), and torque specs for all fasteners you move during the job. Special tool descriptions, so you can fabricate your own tools, if you are cheap like me! A great source of info!
