Hardened tooth surface via professional carburizing quenching, strong shock load resistance for continuous heavy-duty harvest work. Effectively avoid tooth chipping, rapid abrasion and fracture under full grain tank pressure.
21-tooth bevel structure and inner keyway fully identical to original parts, tight gear meshing, low running noise, no slippage during grain unloading. No cutting, reaming or adjustment required during installation.
Internal metal stress eliminated by annealing process, greatly reduce deformation under long-time alternating load. Anti-rust oil prevents oxidation during sea transportation and humid farm environment in Brazil, Argentina, USA.
Much more competitive price than genuine OEM parts with equivalent durability. Perfect bulk supply for agricultural spare parts wholesalers, farm service stations and harvester rental companies.
Every gear undergoes tooth hardness test, dimensional inspection and concentricity check before delivery. Stable batch quality, support long-term bulk order & mixed container loading with other Case IH transmission gears.
Mainly used in lower unloading auger gearbox of Case IH axial flow combines, responsible for power drive of grain delivery auger. Widely applied for corn, soybean, wheat and rice harvesting across South America, North America and Europe agricultural regions.
This drive gear is mainly used in the lower unloading auger gearbox of Case IH axial flow combine harvesters. It plays a critical role in providing power transmission to drive the grain delivery auger during harvesting processes.
Yes, it features a 1:1 exact matching 21-tooth bevel structure and inner keyway matching the OEM specifications. It requires no reaming, cutting, or special modifications for installation.
This aftermarket drive gear is compatible with models 1640, 1644, 1660, 1666, 1680, 1688, 2144, 2166, 2188, 2344, 2366, 2377, 2388, 2577, and 2588.
Each gear undergoes carburizing quenching to harden the outer surface for wear resistance, coupled with an annealing process to relieve internal stress and prevent structural deformation under continuous, heavy agricultural loads.
A layer of anti-rust oil is applied to the surface of the gear to prevent oxidation and moisture damage during sea transport and storage in humid environments common to farming regions.
