Overview
The ZF 4657.362.003 FLANGE SHAFT is a critical output component engineered specifically for the WG 210 Series transmission. This OEM genuine part transmits rotational torque from the planetary gear set to the driveline, ensuring precise power delivery in heavy-duty industrial applications. As the primary interface between the transmission internals and the output yoke, the flange shaft (SKU: 4657.362.003) must maintain exacting concentricity and surface finish to prevent vibration and premature wear. It integrates directly with the 4657101042: TRANSMISSION HOUSING and is secured within the 4657201028: HOUS.FRONT SECT assembly, making it a non-negotiable element for drivetrain integrity.
Symptoms of Failure
When the ZF 4657.362.003 flange shaft deteriorates, operators typically encounter these specific failure indicators:
- Output flange oil leakage – Worn sealing surfaces allow transmission fluid to escape past the shaft, often visible as drips near the rear housing joint.
- Driveline vibration under load – A bent or spline-worn shaft causes noticeable shuddering during acceleration, particularly in WG210-equipped vehicles.
- Abnormal gear engagement noise – Loose fitment between the shaft and the 4657201013: HOUSING REAR PART produces a distinct clunking sound when shifting between forward and reverse.
- Intermittent power loss – Stripped or cracked splines on the flange shaft result in momentary torque slip, mimicking clutch failure.

Compatibility
This flange shaft is primarily designed for the ZF WG 210 Series, but it also fits select models within the WG180 and WG200 families due to shared output shaft dimensions. It is commonly found in WG210, WG200, and WG180 transmissions used in municipal trucks, construction loaders, and agricultural tractors. Always verify spline count and pilot bore diameter against your specific transmission serial number. The shaft is retained using a 0631306792: CYLINDRICAL PIN and sealed by the rear housing assembly.
