ZF 4642.303.020 OUTPUT FLANGE for WG150 | OEM Genuine Part

Overview

The ZF 4642.303.020 OUTPUT FLANGE is a critical driveline component engineered for the WG150 series transmissions. 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 differential. Machined from high-strength forged steel, the flange ensures precise alignment and vibration-free power delivery. The SKU 4642.303.020 is a direct replacement for worn or damaged flanges, restoring factory-spec performance. It mounts directly onto the output shaft within the TRANSMISSION HOUSING and is secured using the GROOVED STUD for a locked fit.

Symptoms of Failure

• Transmission fluid seepage at the output shaft: A degraded flange seal or worn splines allow oil to escape, leaving puddles under the vehicle.
• Driveline vibration during acceleration: A loose or cracked output flange causes imbalance, leading to shuddering at highway speeds.
• Clunking noise when shifting gears: Excessive play between the flange and output shaft creates audible metallic impacts, especially in reverse.
• Premature bearing wear in the transmission housing: A failing flange misaligns the shaft, accelerating damage to internal components like the TRANSMISSION HOUSING.

Technical Specifications

Compatibility

This output flange is specifically designed for the ZF WG150 series transmission. It is also compatible with the WG180 and WG200 variants when used with the correct TYPE PLATE for identification. The flange fits all WG150 models produced after 1998, including those in municipal trucks, construction loaders, and agricultural tractors. Always verify the spline count and bolt pattern against your existing flange before ordering.
