Abstract
A rotating brush assembly for a street sweeper utilizes a hub to connect a hydraulic pump to a rotatable brush plate. A collar on the hub extends upwardly from a base flange and a tapered bore extends through the collar and the base flange and receives a mating tapered portion of a rotatable shaft of the pump. A downwardly extending rim on the bottom of the base flange locates the hub relative to a central aperture in the brush plate. The bottom of the base flange includes a recess which extends upwardly from the rim. The tapered bore communicates with the recess. The recess receives a threaded bottom portion of the rotatable shaft of the pump and a nut which is disposed on the threaded portion of the pump shaft.
