Take
loose the 4 bolts that secure the final drive to the swingarm. Gently pull the final drive straight back from the swingarm until it disengages. The drive shaft will most probably come out with the final drive. Pull the drive shaft out of the final drive and set it to the side. Be careful not to lose the spring that inserts into the end of the drive shaft. Set the final drive and plastic trim ring to the side and be sure to prop it up a bit so the vent is higher than the filler, or oil may drain out of the drive.
