45 tooth race for Allison transmission

The 45 tooth race acts as a bearing surface within the transmission gear assembly. It provides the necessary track for rolling elements to facilitate the rotation of gears while managing radial and axial loads. This component is designed to maintain the alignment and smooth operation of the gear train within Allison transmission systems.

This part is manufactured by Allison and is identified by part number 6774709. It is engineered to meet specific tolerances for integration with the associated 45-tooth gear and bearing elements. It is compatible with various Allison transmission models used in heavy machinery, cranes, and commercial vehicles.

A bearing race functions as the inner or outer ring of a rolling-element bearing. It provides a hardened, precision-ground surface that allows balls or rollers to move with minimal friction. Proper fitment of the race is necessary to ensure the transmission operates within specified parameters, as it directly influences the clearance and load distribution of the rotating assembly.
