WG2210100028 is the genuine Sinotruk Howo flange, a precision‑engineered chassis component used in driveshaft and transmission connections. This critical part belongs to the trusted family of Sinotruk Howo parts, ensuring accurate alignment and torque transfer between the gearbox output and propeller shaft. Manufactured from high‑strength forged steel with induction‑hardened splines and precisely drilled mounting holes, it guarantees durability and perfect fit. Designed to handle heavy‑duty loads, this flange meets OE standards for concentricity, balance, and corrosion resistance, keeping your Howo driveline reliable mile after mile.
The WG2210100028 flange is forged from high‑strength alloy steel (40Cr or equivalent) and heat‑treated to achieve a tensile strength exceeding 800 MPa. Its splines are precision broached and induction‑hardened to resist wear, while the pilot diameter is machined to a tolerance of ±0.05 mm, ensuring perfect centering with the transmission output shaft.
Key dimensions: overall diameter 165 mm, bolt circle 135 mm with eight equally spaced holes for M14 studs. The spline count is typically 16 teeth, matching the Howo HW series gearbox output. A zinc‑nickel coating provides corrosion resistance for over 500 hours salt spray protection.
The WG2210100028 flange is rated to handle dynamic torque up to 25,000 Nm, matching the capacity of Howo HW19710 and HW19712 transmissions. It withstands static loads exceeding 150 kN and has been fatigue‑tested for over 1 million cycles under full load, ensuring long‑term reliability in heavy‑haul applications.
Operating temperature range: -40°C to +120°C. The flange’s balanced design minimizes vibration and runout, critical for driveline longevity. Maximum allowable imbalance is less than 15 g·cm, meeting stringent OE requirements for smooth power transmission.
The WG2210100028 flange is a direct OE replacement for Howo transmissions HW19710, HW19712, and HW25716. It bolts directly to the output shaft and accepts the companion flange of the front driveshaft. Always verify the spline count and pilot diameter match your specific gearbox.
Compatible with all Howo chassis models (6×4, 8×4, 4×2) from 2005 onward. It also fits certain Shaanxi and Foton trucks using identical Fast Gear transmissions. The flange is marked with the WG2210100028 part number for easy identification.
Before installing a new WG2210100028, clean the output shaft splines and apply anti‑seize. Slide the flange onto the shaft, align the bolt holes, and install the retaining nut (torque to 450‑500 Nm). Use a dial indicator to check radial runout; it should not exceed 0.1 mm. Re‑torque after 1000 km.
During routine maintenance, inspect the flange for cracks, spline wear, or corrosion. If driveline vibration appears, check the flange runout and torque. The Flange is designed for the life of the transmission, but should be replaced immediately if any damage is detected to prevent driveshaft failure.
Genuine Sinotruk Howo parts like the WG2210100028 flange are manufactured to exacting tolerances, ensuring perfect spline fit, correct pilot centering, and optimal torque capacity. Non‑genuine flanges may have inferior steel, incorrect hardness, or poorly cut splines, leading to premature wear, driveline vibration, and even catastrophic failure. Using genuine parts guarantees that your Howo transmission and driveshaft remain properly aligned and balanced, reducing downtime and maintenance costs. The complete range of Sinotruk Howo parts is available through our network, including engine, gearbox, chassis, and cabin components – all backed by factory quality assurance and traceability.
The WG2210100028 flange is a critical link in the Howo driveline, transferring engine torque from the transmission to the propeller shaft. Its robust construction withstands the shock loads of off‑road operation and the constant stress of highway hauling. Regular inspection of this flange, especially after heavy use, can prevent unexpected breakdowns and extend the life of U‑joints and bearings.
When replacing the Flange, always use new lock nuts and ensure the flange face is clean and free of burrs. The pilot diameter must be checked for ovality; if out of round, the transmission output shaft may also be damaged. Genuine parts are stamped with the OEM number and heat‑lot code, ensuring full traceability and compliance with original specifications.
