I did my 02 track just this spring and used this link, great info. The spedo is diff but comes apart the same. Other than that it was pretty straight forward. take your time and take lots of pic of the chain case gears and such if you are new to this like i was. The pics really helped when going back together. Start spraying that drive bearing set screws with PB blaster or a WD 40 as they like to rust on the shaft. Mine came right off but i started spraying it a few days before. Good luck and ask back with any questions.
