MM 430035 Brush Drive Hub for Minuteman Power Boss Scrubbers. Durable molded plastic drive hub with brass insert. Includes key. This hub is used for mounting Minuteman and some Power Boss scrub brushes with the 6 point hex drive. These brushes tend to "snap-on". This drive hub does not fit newer Power Drive type clip-on scrub brushes or models which require 3 mounting lugs. This hub attaches directly to the disc brush drive motor with included keyway/key. Does not include additional mounting hardware such as the retaining bolt or washers which "pin" the hub to the female threaded drive motor shaft. Sold each. Fits many popular Minuteman scrubbers including 170, 170TD, 200, 28B, 32B, 200TD, 200B, 200B-TD, 200E, 240X, 260, ES260, E260TD, 320, 340 Sweeper/Scrubber, 380 and many other models. Please check your parts manual before ordering. Replaces Minuteman / Power Boss 430035, 430035-1.
