Remove the bottom cover of the sweeper head, then remove the brush roller along with the belt if still there. Clean the brush end-bearings--the roller ends and the interior of the bushings. Then oil the bearings lightly with 3-1 oil or similar. Place the new belt over the roller and the motor shaft adding any required belt twist (diagram on the casting), then seat the roller and bearings as a unit. Replace the cover and test the roller for running. Hope this helps!
