ZF 4616.303.041 OUTPUT FLANGE for WG65 | OEM Genuine Part

Overview

The ZF 4616.303.041 OUTPUT FLANGE is a critical driveline component engineered specifically for the WG 65 Series transmission. This OEM genuine part serves as the mechanical interface between the transmission output shaft and the propeller shaft or drive axle, transferring rotational torque from the gearbox to the vehicle’s wheels. Located at the rear of the transmission housing, the output flange is splined to the output shaft and secured via a central nut, ensuring precise alignment and zero backlash under heavy loads. The SKU 4616.303.041 is manufactured to ZF’s exacting tolerances, guaranteeing a direct bolt-on replacement without modification.

Symptoms of Failure

• Transmission fluid leakage at the rear seal: A worn output flange often damages the sealing surface, causing oil to weep or stream from the output shaft area, leading to low fluid levels and potential gearbox damage.
• Vibration or driveline shudder during acceleration: Excessive play in the spline engagement or a bent flange face creates imbalance, transmitting harsh vibrations through the chassis at highway speeds.
• Clunking noise when shifting between drive and reverse: Worn splines on the flange allow rotational slop, producing a distinct metallic clunk as torque is applied or released.
• Premature wear of the output shaft bearing: A loose or distorted flange places axial stress on the bearing, accelerating failure and potentially requiring a full transmission rebuild.

Technical Specifications

Compatibility

This output flange is primarily designed for the ZF WG 65 Series transmission family. Based on its spline geometry and bolt pattern, it is also compatible with the following ZF models: WG180, WG200, WG210, and WG250 series transmissions used in medium- to heavy-duty commercial vehicles, buses, and off-highway equipment. Always verify your transmission model and output shaft configuration before ordering.
