ZF 4657.304.010 OUTPUT SHAFT for WG210 | OEM Genuine Part

Overview

The ZF 4657.304.010 OUTPUT SHAFT is a critical rotating component engineered specifically for the WG 210 series transmission. This OEM genuine part transmits torque from the planetary gearset to the driveline flange, ensuring smooth power delivery under heavy-duty industrial loads. The SKU 4657.304.010 is precision-machined to maintain exact concentricity and spline engagement, directly interfacing with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to form the primary rotating assembly. Without this shaft, the transmission cannot transfer engine power to the wheels or driven equipment.

Symptoms of Failure

• Oil leaks at the output flange seal: A worn or scored output shaft surface damages the lip seal, causing transmission fluid to weep or stream from the rear housing joint.
• Gear slipping under load: When splines on the 4657.304.010 wear, the shaft loses positive engagement with the clutch hub, resulting in intermittent power loss during acceleration or uphill operation.
• Vibration and driveline shudder: Bearing journal wear on the output shaft creates radial play, producing low-frequency vibration that intensifies at highway speeds.
• Metallic debris in transmission fluid: Flaking or spalling on the shaft surface introduces ferrous particles into the oil, often detected during routine filter inspections.

Technical Specifications

Compatibility

This output shaft is designed for the ZF WG 210 series transmission. It is also compatible with the WG 180, WG 200, and WG 220 series models that share the same output shaft spline count and bearing journal dimensions. The 4657.304.010 integrates directly with the HOUSING REAR PART and is secured using a CYLINDRICAL PIN to prevent rotational misalignment. Always verify your transmission model code before ordering.
