F5864-900 Hoover Steamvac Brush issue

[Indiana]

The brushes on my hoover stopped working, they just don't spin anymore.
I took it apart and it appears to be powered by suction(it has a small turbine in it). The gears all seemed to mesh properly and I got it spin like it should. It still will not spin the brushes though, anyone know of common issues with these? I can't seem to find the problem.

Thanks,
Indiana
