How to Adjust and Change the Brush Roll on your Oreck U2000R Upright Vacuum:
To determine if the brush is worn, place a firm straight edge across the nozzle opening. If the bristles do not extend beyond the base plate, you should adjust the brush.
Remove the base plate by removing 5 screws. Then, remove the belt and brush roll from the housing.
Rotate both bearing assemblies at ends of brush roll to show "old" and replace in the holding channels in the housing.
NOTE: The bearing assembly setting marked "OLD" has two bars ( II ) on the top of the assembly. The one marked "NEW" has one bar ( I ). When rotating bearings, make sure both bearing assembly settings are the same and face up when replacing the brush roll.
Reassemble the belt and the base plate and check bristle height above base plate at each end of brush. If a previous adjustment has already been made and bristle height does not extend above base plate, a new brush assembly should be ordered.
IMPORTANT: Unless the brush is worn as indicated above, both bearings must
be in the new position. When rotating, both
bearings must be in the old position. Unmatched settings will cause damage to your machine.
