Remove the front wheel in your variator system. The front wheel is part of a pulley system and it is held in place by a single bolt through its center point. In order to remove this bolt, you will either need an air-powered impact wrench, or a strap wrench and a socket wrench. The impact wrench is powerful enough to loosen and remove the bolt without turning the pulley wheel. Or, you can secure the front wheel with the strap wrench and remove the bolt with a hand-operated socket wrench.
