This document provides installation instructions for a drive wheel/drive wheel hub replacement kit for Tennant T12, T16, and T16AMR scrubbers. The kit installation is intended to be performed by TennantTrue® service or an authorized service provider.

Function Description:

The primary function of this kit is to replace the drive wheel and its associated hub on the specified Tennant scrubber models. This replacement is crucial for maintaining the machine's mobility and operational efficiency. The drive wheel is a key component in the scrubber's propulsion system, enabling it to move forward, reverse, and maneuver during cleaning operations. A worn or damaged drive wheel or hub can impair the machine's movement, reduce cleaning effectiveness, and potentially lead to further mechanical issues. The replacement process involves removing the old wheel and hub assembly and installing new components, ensuring the scrubber can continue to operate smoothly and reliably.

Important Technical Specifications:

The document details several technical specifications related to the installation process, particularly concerning torque values for fasteners.

Socket Screws (Hub Installation): The six socket screws used to install the new hub onto the new wheel must be torqued to 20 Nm (14.75 ft. lbs.). This precise torque ensures a secure and stable connection between the hub and the wheel, critical for the drive wheel's structural integrity and safe operation.
Hex Screws (Wheel Assembly): The four hex screws that secure the wheel to the drive wheel assembly must be tightened to 40 Nm (29.5 ft. lbs.). These screws should be tightened in a star pattern to ensure even pressure distribution and proper seating of the wheel. The document notes that achieving final torque may require the machine to be lowered to the floor if it was jacked up during installation, highlighting the importance of proper torque for operational safety and longevity.
