Bearing kit for Allison CT/HT-700

The 6839821-S bearing kit provides the essential rolling elements and support surfaces required for the internal operation of Allison automatic transmissions. By facilitating the rotation of shafts and gear assemblies, these components manage radial and axial loads while minimizing friction within the transmission housing. This kit is intended for use during transmission overhaul or repair procedures to restore proper mechanical movement.

This assembly is compatible with Allison CT/HT-700 and V700 series transmissions, which are commonly found in heavy-duty machinery such as industrial cranes, heavy transport trucks, and construction equipment. The kit contains specific bearings selected for their dimensional accuracy and load-bearing capacity to meet the original design requirements of these transmission series.

Bearings within a transmission system maintain the alignment of rotating components and support the torque transfer between gears. Over time, these components are subject to mechanical stress and wear, which can lead to increased friction and heat if not addressed. Proper installation of these bearings ensures that the transmission shafts remain centered and operate with the necessary clearance for efficient power transmission.
