Product Description
503814 Grain unloading sprocket is heavy-duty transmission sprocket specially built for CLAAS combine harvesters.
**Material features**: Made of high-grade alloy steel with tooth surface quenching hardening treatment. Precision machined tooth profile provides excellent wear resistance and impact toughness, resisting heavy torque load and continuous shock during long-time grain unloading operations in dusty farm environments.
**Product characteristics**: This sprocket belongs to grain unloading transmission assembly. It meshes perfectly with roller chain and drives the unloading auger to transfer grain out of the grain tank. Worn teeth, broken teeth or cracked tooth root will cause chain jumping, slipping and grain unloading blockage, leading to harvest interruption and loss of working time.
**Compatibility**: Direct aftermarket replacement matching OEM 503814, fully compatible with CLAAS Lexion Combine, CLAAS Tucano Combine, CLAAS Jaguar Forage Harvester, CLAAS Conspeed Corn Header. Inspect matched chain and bearings, adjust chain tension properly after installation. Install 503814 grain unloading sprocket to restore efficient grain discharge performance for your Claas combine harvester..
