To change the final drive belt on your Fatboy, first disconnect the battery. You have to drain the primary and remove the cover. Take the engine sprocket nut loose and remove the plate in the center of the clutch assembly. Remove the mainshaft nut that holds the clutch assembly on. This nut has LEFT HANDED THREADS. Then, remove the starter jackshaft. Go the right side of the bike and remove the exhaust system so that you can remove the starter. Then take the inner primary cover off. You may have to remove the front belt drive pulley. Since you're in this far, you may as well remove the pulley if you have the proper tools and replace all the transmission seals behind it. Then, remove the rear wheel and the swingarm. Do not bend the new final drive belt into a radius any tighter than about four inches or you may damage the cords inside the belt. You will need a torque wrench that is capable of applying at least 150 foot pounds of torque to the engine sprocket nut and torqe 60-80 pounds in the LEFT HANDED DIRECTION for the clutch assembly. The front belt drive pulley torques to 150-165 foot pounds as is also LEFT HANDED THREADS and you'll need a "belt pulley locking device" to hold it while you take the large nut off and put it back on. If you plan on doing this job, I would advise the purchase of a service manual as sometimes a picture is worth a thousand words.
Good Luck
