Overview
The ZF 4616.329.004 CONNECTING FLANGE is a critical OEM genuine component engineered for the WG 65 Series transmission. This precision-machined flange serves as the primary interface between the transmission output shaft and the driveline, ensuring secure torque transfer and proper alignment. The SKU 4616.329.004 is specifically designed to withstand high torsional loads and thermal cycling in heavy-duty industrial applications. When installed correctly, this connecting flange works in concert with the 4616101059: TRANSMISSION HOUSING to maintain structural integrity under extreme operating conditions.
Symptoms of Failure
- Oil seepage at the flange-to-housing joint – A worn connecting flange often causes transmission fluid leaks around the mating surface, especially during high-pressure operation.
- Driveline vibration or shudder – When the flange splines wear unevenly, operators may notice increased vibration during gear engagement or acceleration.
- Difficulty maintaining gear engagement – A damaged flange can cause intermittent slipping or delayed engagement, particularly in WG65 transmissions under load.
- Metallic debris in transmission fluid – Flange wear generates fine metal particles that contaminate the oil, often detected during routine filter changes.

Compatibility
This connecting flange is primarily designed for the ZF WG 65 Series, but it also fits select models in the WG180 and WG200 families when used with the appropriate 0636011038: HEXAGON SCREW and 0636011118: HEXAGON SCREW fasteners. For proper installation, always pair this flange with the 0636016015: HEXAGON SCREW kit to achieve correct torque specifications. The part is compatible with WG65, WG180, and WG200 transmissions manufactured after 2010.
