About this file
This document is a product specification sheet for the Bauer Model 8731 Wheel Assembly Torque System, a specialized equipment designed for aircraft wheel assembly and maintenance. The system is a comprehensive torque solution for aircraft main and nose wheel tire bolt installation, featuring a touch-screen interface, dual spindle configuration, and programmable torque/angle control. It is available in three torque range configurations: low (23-265 FT/LB), medium (34-368 FT/LB), and high (52-545 FT/LB), with dimensions of 152 inches wide, 90 inches deep, and 124 inches tall, weighing approximately 1,300 pounds.
The product is specifically related to a Department of the Air Force Air Mobility Command solicitation (FA442725Q1097) for the 60th MXS Wheel and Tire Shop at Travis Air Force Base, which requires this equipment for assembling wheels for C-17, C-5, and KC-46 aircraft. The solicitation was a brand-name requirement for the Bauer Model 8731 Wheel Assembly Torque System and Model 8071 Wheel Build-Up, though the opportunity was ultimately canceled for fiscal year 2025. Optional features include an electric hoist, torque verification kit, and a printer for generating reports, with companion products like wheel adapters, bead breakers, and tire inflators also available.
