① Product Overview — 199497C1/176278C2 Driven Sprocket For Case-IH Corn Head
The 199497C1/176278C2 Driven Sprocket For Case-IH Corn Head is a critical agricultural sprockets component engineered to deliver precise torque transmission within combine harvester chain drive systems. Operating on the fundamental roller-chain meshing principle, each tooth profile is precision-hobbed to ISO 606 tolerances, ensuring smooth chain engagement, minimal vibration, and maximum power transfer efficiency throughout the harvesting cycle.
This sprocket’s primary function is Gathering chain driven sprocket for Case-IH and International Harvester corn head attachments. It replaces worn or damaged OEM drive components, restoring original transmission ratios and protecting downstream driveline components from premature wear. Whether you operate a grain combine in the wheat belt, a corn head on row-crop acres, or a self-propelled forage harvester, maintaining the integrity of your chain drive sprocket system is essential to uninterrupted seasonal throughput.
Compatible with the following equipment: Case IH Corn Head (800-900-1000 Series): 1043, 1044, 1054, 1063, 1064, 1083, 1084; International Harvester Corn Head: 824, 833, 834, 844, 853, 854, 863, 864, 873, 874, 883, 943, 944, 954, 963, 964, 983, 984. Our agricultural sprockets Australia customers rely on this part during peak harvest windows when equipment downtime is simply not an option.
② Australian Agricultural Application Scenarios
Australia’s broadacre grain belt — stretching from Western Australia’s Wheatbelt through South Australia’s mid-north to Queensland’s Darling Downs — demands farm machinery components that perform flawlessly through long, dusty harvest runs. The 199497C1/176278C2 Driven Sprocket For Case-IH Corn Head is engineered to meet these exacting requirements, having been specified by Australian dealers and farm service agents as a cost-effective harvester sprocket replacement for Case IH Axial-Flow 9250 and 8250 combines.
In Western Australia’s wheat belt, machinery operates for 12–16 hours per day during the short November–December harvest window. A failed drive sprocket can bring an entire header to a standstill, costing growers thousands of dollars per hour in lost capacity. Our sprocket’s induction-hardened tooth profile resists the abrasive silica dust endemic to South Australian Yorke Peninsula grain crops and WA broadacre, dramatically outperforming standard-grade components.
In Queensland’s sugarcane belt, harvester drive sprocket components face added humidity and crop residue loading. Our alloy steel construction with anti-corrosion surface treatment withstands these tropical conditions. Whether used in Mackay’s cane country or the Lockyer Valley’s mixed vegetables, this agricultural sprocket delivers consistent performance across Australia’s diverse farming landscapes.
- ✅ Compatible with Case IH Axial-Flow 9250 and 8250 combines operating in Australian conditions
- ✅ Engineered for abrasive WA silica dust and QLD humidity extremes
- ✅ Preferred by Australian John Deere, Case IH, and New Holland dealerships as a cost-effective OEM alternative
- ✅ AS 2397-compliant manufacturing philosophy for safe machinery operation
③ Product Specifications & Selection Guide
Selecting the correct agricultural chain sprocket requires matching three key parameters: number of teeth (which governs speed ratio), chain pitch (which must align with your roller chain standard), and bore / shaft interface (keyway, spline, or hex bore). The 199497C1/176278C2 Driven Sprocket For Case-IH Corn Head has been designed to these exact OEM dimensions, enabling drop-in replacement without modification.
Material options available: Our standard production uses 45# carbon steel (equivalent to C45 / 1045 grade) with high-frequency induction quenching applied to the tooth faces, achieving surface hardness of HRC 45–55 while maintaining a tough core. For extremely abrasive crop residue environments — such as rice-straw or canola stubble in Australia — we offer 40Cr alloy steel or 20CrMnTi carburized variants for superior case depth.
