How do I change the drive belt on speedfight 2 50cc?

i can tell you how to change the belt but im confused on the servive it bit?
take the transmission cover off by removing all the 8mm hex headed bolts from around its edge,leave the kickstart where it is,undo the nut in the middle of the variator (round thing on the left) and undo the nut on the clutch bell(round thing on the right)slide the clutch bell off and pull the belt out of it put the new one on and make sure if its directional it the right way around the arrow of travel will be facing left on the top of the belt,then put the clutch bell back on the shaft and pull the belt into the middle of it if you can,then put the blt over the variator centre and refit the outer variator half and put some loctite on the thread of the nut make sure its tight .i use an impact gun as it has to be very tight or it falls off and wrecks the parts.
