Do the pulley teeth look oddly sharp, inconsistent, or warped?
Notice how the pulley has teeth that are wider at the edges, then get narrower and sharper towards the middle.
If your pulley looks worn please notify support at firstname.lastname@example.org with the subject "Worn Pulley, Picture and Video Attached". Include a zoomed picture similar to the ones below. Also, please include a video like this one with your belt cover removed, gently hitting the throttle. Once we receive these we'll walk you through how to receive and install a replacement.
While waiting for the replacement pulley please replace your parts and components, to ensure you do not lose them.

You may need to twist the wheel while pushing to get the drive gear teeth to catch the belt.
