Product Description
666911 Chain sprocket is heavy-duty chain drive sprocket designed for CLAAS agricultural harvesting machines.
**Material features**: Made of high-grade alloy steel with tooth surface quenching heat treatment. The sprocket teeth achieve high hardness and outstanding wear resistance, resisting abrasion, chipping and fatigue damage under continuous heavy loads and strong vibration in farm conditions. Precision machined tooth profile guarantees smooth meshing with roller chain.
**Product characteristics**: This chain sprocket works with roller chain to transfer power, driving corn header, grain elevator and crop conveying assemblies. Worn, chipped or deformed sprocket teeth will lead to chain jumping, abnormal noise and sudden power loss, causing unexpected machine shutdown in harvest season.
**Compatibility**: Direct aftermarket replacement matching OEM 666911, 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 after installation. Install 666911 chain sprocket to restore stable power transmission of your harvester.
