== Roues dentées et les chenilles ==

* Place an idler sprocket (pignon) on each shoulder bolt, followed by a washer. The side of the sprocket with “teeth” should face the same direction as the threaded end of the bolt, so that the teeth end up pointing in towards the chassis.

* Placez les roues dentées libres (à pignon) sur chacune des vis à l'arrière du du Zumo. Placez une rondelle entre la roue et le chassis. The side of the sprocket with “teeth” should face the same direction as the threaded end of the bolt, so that the teeth end up pointing in towards the chassis.

* Insert the shoulder bolts through the side of the chassis into the nut. Use a 3 mm hex key (Allen wrench) to tighten the bolts until the washers are snug against the chassis. {{underline|Be careful not to overtighten the shoulder bolts}} as doing so can bend the washers. '''Note:''' Be careful if you use threadlocking adhesives like Loctite as these can corrode the chassis. You should first test any such adhesives on a concealed part of the chassis to ensure they will not damage it.
