Where the gearbox sprocket would be is shifted through 90 degrees. A drive shaft is connected, on a universal joint, between the gearbox and the back wheel 'bevel box' hub. The bevel box contains a bevelled pinion gear, on the end of the drive shaft, which connects to a bevelled crown wheel attached to the wheel hub; like half a reverse engineered car differential. The drive shaft is often enclosed in one leg of the swing arm, to which the bevel box hub is also attached.
The bearing lets the belt pully free wheel on the compressor input shaft that the clutch is attached to.
The rubber membrane over the radio buttons has to be pulled out to reach the shaft of the steering column. Remove the screws holding the turn signal mechanism and the handle attached to it. Gently pull the mechanism out and away from the shaft. The center of the wheel is attached to the shaft by a nut on a splined shaft. After removing the nut the wheel can be wiggled and pulled off; UNLESS it is a tilt-steering mechanism. They have an extra screw on the right side of the column that requires a special tool to remove. Most part stores will have it.
