Replacing Drive Cog Bearings and Drive Chain

A quick DIY on how to replace the drive cog bearings in a 2002 Arctic Cat ZR 600. I didn't actually change the bearings in the picture montage, just explained how to do so, hopefully this helps out a bit. I did this as a graphic design project in college. I believe the secondary clutch bolt is actually a 13mm, a few other nut/bolt sizes may be off. Good luck on this process, a second set of hands will help out a lot.
