If your excavator is making grinding noises during turns or struggling to track straight, a worn replacement final drive or swing gearbox is often the culprit. As the mechanical muscle of your machine, high-torque gear assemblies translate hydraulic power into the massive force needed for rotation and travel. BeeSpareParts stocks a wide range of planetary gear sets, sun shafts, and ring gears built to withstand the extreme shock loads of heavy digging and rocky terrain.
Drive system failures are often progressive. To extend the life of your gears, we recommend regularly browsing our for leaks, or checking our if you notice oil weeping from the sprockets. Our final drive assemblies are direct-fit alternatives to expensive OEM units, featuring precision-hardened steel components to prevent tooth chipping and internal overheating.
Whether you need a swing reducer for a 20-ton excavator, a travel gearbox for a mini-digger, or replacement planetary gears, our parts are factory-tested for load-bearing capacity and ready for fast international shipping. Restore your machine's mobility and rotation—order your heavy-duty drive solutions today.
