Product Uses
Integrated into the cleaning system of combine harvesters, this impurity gearbox assy drives vibrating screens and air selection devices. It separates impurities—such as stems, roots, stones, and dust—from grains, improving the purity of the harvested crop.
Designed specifically for impurity removal subsystems, the gearbox transmits power to impurity removal screws. It ensures efficient discharge of debris, preventing clogs and maintaining the flow of crops through the harvesting process.
Tailored for FM WORLD harvesters, this gearbox assy is a direct replacement for original components. It fits seamlessly into the harvester’s existing power transmission system, ensuring optimal performance without modifications.
In high-yield fields where crop density is high, the impurity gearbox assy delivers consistent performance. It handles increased volumes of crops and debris, preventing system overload and maintaining harvesting efficiency.
By ensuring thorough impurity removal, this gearbox supports green agricultural practices. It reduces waste and improves the quality of grains, making them suitable for direct use or further processing without additional cleaning steps.
Product Operate Guide
Before installing the impurity gearbox assy, inspect the mounting surface to ensure it is flat and free of debris. Check that all mounting bolts are in good condition and compatible with the gearbox. Verify the axial and radial clearance of the gearbox to ensure it meets the harvester’s specifications.
Align the gearbox with the mounting points on the harvester’s cleaning system. Secure the assembly using the recommended bolts, tightening them evenly to ensure a stable fit. After installation, fill the gearbox with the appropriate type of lubricating oil as specified in the harvester’s manual. Check the oil level to ensure it is within the recommended range, avoiding overfilling or underfilling.
During harvesting operations, monitor the gearbox for abnormal noises or vibrations. Unusual sounds may indicate bearing damage, gear meshing issues, or foreign objects entering the component. Keep an eye on the harvester’s cleaning performance—decreased impurity removal efficiency may signal a problem with the gearbox.
Regularly clean the gearbox casing and ventilation holes to remove dust, debris, and crop residues. This ensures proper heat dissipation and prevents buildup that can cause overheating. Inspect the seals regularly to prevent lubricant leakage and protect internal components from moisture and dust. Replace the lubricating oil at the recommended intervals, or after the first use if the gearbox is new or has been replaced. Store spare harvester parts in a dry, clean area to ensure they are ready for quick replacement if needed.
