-  * For the swing arm its pretty easy when you know how it works. The pivot bolt when tightened presses the inner bearing and race,​bearing spacer, and dust shield onto both sides of the frame and the actual adjustment is done by tightening bearing locknut on the right side till you have the desired preload once the preload is set then comes the lock-ring so the right bearing locknut cant turn.
