A scooter runs by transferring power from the engine to its drive belt, which in turn powers the rear wheel, propelling the scooter forward. If your scooter's drive belt is worn or loose, it may need to be replaced to ensure the scooter is operating at full capacity. Replacing a scooter's drive belt requires you to open the scooter's drive belt case, remove both the drive belt system's gear wheels and pull the old belt from the gear rods that hold it in place.

Unscrew the bolts around the outside of the scooter's drive belt case, starting with the bolt on the bottom of the case underneath the kick start. From that bolt, go across the case to the bolt directly across the case in the top right, then the bolt directly below in the bottom left, then the bolt directly across in the top left and so on until all six bolts are removed. This will prevent the weight of the case's lid from damaging the bolts holding it in place.
Remove the drive belt case's lid. Pull the lid straight back so as to cleanly disengage the internal components of the kick start from the drive belt system.
Secure the front gear wheel by placing a bolt in the hole below the wheel located toward the bottom and to the left of the wheel, wedging the head of a flathead screwdriver in the teeth of the gear wheel and levering the screwdriver against the bolt. Pinch and hold the bolt and screwdriver together with pliers.
Remove the bolt in the centre of the front gear wheel with an impact wrench. Hold the screwdriver wedge firmly in place as you use the impact wrench.
Pull the front gear wheel off.
Remove the rear gear wheel using the same screwdriver wedge as you did with the front gear wheel.
Disengage and remove the drive belt. You may need to use pliers to get an adequate grip on the belt.
Loop the replacement drive belt over the rear gear rod and hook the front of the belt over the front gear rod.
Hammer the belt onto the front gear rod with a rubber mallet.
Put the gear wheels back onto the gear rods, using the screwdriver wedge to secure the wheels in place as you tighten the bolts holding them in place.
Replace the drive belt case lid and secure it with the bolts, following the pattern in Step 1.
