Tennant Drive Brush Plug for Floor Scrubbers 1056155 – TN1056155

This drive brush plug is built for Tennant floor scrubbers, serving as the mounting hardware that secures the scrubbing brush or pad driver to the machine's drive plate. The plug threads or locks into the brush assembly so the brush spins with the drive plate instead of slipping loose during scrubbing.

This part has since been superseded by an updated part number from Tennant, though the original number remains a valid reference for identifying the correct replacement. It weighs 0.40 pounds, consistent with a small plastic or composite fastening component rather than a structural machine part.

As a wear item, a drive brush plug is subjected to repeated rotational torque and contact with cleaning solution every time the scrubber runs, and over time the mounting threads or locking tabs can wear, crack, or strip, which lets the brush wobble or detach entirely during operation. A worn plug typically shows up as uneven scrubbing, a rattling brush deck, or a brush that will not stay seated. Replacing it restores a secure connection between the brush and drive plate so cleaning performance stays consistent across the machine's operating life.
