ZF 4644.303.271 OUTPUT FLANGE for WG200 | OEM Genuine Part

Overview

The ZF 4644.303.271 OUTPUT FLANGE is a critical driveline component engineered specifically for the WG 200 Series transmission family. This OEM genuine part serves as the mechanical interface between the transmission output shaft and the driveshaft, transferring rotational torque from the gearbox to the vehicle’s axles. Constructed from high-strength alloy steel, the flange ensures precise alignment and robust power transmission under heavy-duty operating conditions. The SKU 4644.303.271 is machined to exact ZF tolerances, guaranteeing a secure fit and long service life when paired with the TRANSMISSION HOUSING (4644101232) or the TRANSMISSION HOUSING (4644301282).

Symptoms of Failure

• Transmission fluid seepage at the output shaft: A worn flange seal or cracked flange face often leads to visible oil drips near the rear of the transmission, a common issue in high-mileage WG200 units.
• Driveline vibration during acceleration: When the output flange splines wear or the flange becomes distorted, it causes rotational imbalance, resulting in noticeable shuddering at highway speeds.
• Clunking noise when shifting gears: Excessive play between the flange and output shaft produces a metallic knocking sound, particularly during gear engagement or load changes.
• Premature bearing or seal failure: A loose or damaged output flange can misalign the driveline, accelerating wear on adjacent components like the O-RING (0634306198) and the SCREW PLUG (4475280043).

Technical Specifications

Compatibility

This output flange is designed for the ZF WG 200 Series transmission, which includes models such as the WG180, WG200, and WG210. It is also commonly used in select ZF 4HP and 5HP heavy-duty off-highway variants where the output shaft spline count and pilot diameter match the WG200 pattern. For exact fitment verification, always cross-reference the flange with the TYPE PLATE (0730365067) affixed to your transmission housing.
