Description
The Eaton Fuller mainshaft gear, part number 18440 or HF18440, is a direct-replacement manual transmission gear for Eaton Fuller gearboxes. Mainshaft gears are precision-cut components that ride on or are splined to the main shaft, transmitting torque through the transmission’s gear range. This part is sold individually as a single unit. Because mainshaft gear position and tooth configuration vary across Eaton Fuller transmission models and gear ratios, confirming the exact transmission model and gear position before ordering is strongly recommended. Pro Gear and Transmission carries genuine Eaton Fuller drivetrain components. Not sure this is the right gear for your transmission? Give us a call.
