Overview
The ZF 4657.304.035 OUTPUT SHAFT is a critical torque-transfer component engineered specifically for the WG 210 series of heavy-duty transmissions. This genuine OEM part serves as the final rotational interface between the transmission’s planetary gear set and the driveline, ensuring precise power delivery under high-load conditions. Positioned at the rear of the main housing assembly, the output shaft works in concert with the TRANSMISSION HOUSING to maintain concentric alignment and bearing preload. The SKU 4657.304.035 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn or damaged units in commercial vehicles and industrial machinery.
Symptoms of Failure
- Transmission oil leaks at the rear seal: A worn output shaft bearing journal or surface scoring can degrade the rear oil seal, leading to visible drips or puddles beneath the transmission bell housing.
- Gear slipping under load: Excessive axial play or spline wear on the 4657.304.035 shaft prevents positive engagement with the output flange, causing intermittent power loss during acceleration or hill climbing.
- Vibration and driveline shudder: A bent or fatigued output shaft introduces rotational imbalance, felt as low-frequency vibration through the chassis at highway speeds.
- Metallic grinding noises from the rear housing: Worn splines or bearing race damage produce audible chatter, particularly when shifting between forward and reverse gears.

Compatibility
This genuine output shaft is primarily designed for the ZF WG 210 series, but its spline geometry and bearing dimensions also suit earlier WG 180 and WG 200 variants when used with the correct HOUS.FRONT SECT and HOUSING REAR PART. For WG 250 applications, verify the output flange pilot diameter; the 4657.304.035 shaft may require the HOUSING REAR PART (4472239184) for correct bearing preload. Always cross-reference your transmission’s serial number before ordering.

Frequently Asked Questions
Q: Can the 4657.304.035 output shaft be used in a ZF WG 180 transmission?
A: Yes, the shaft’s spline count and bearing dimensions are shared across the WG 180, 200, and 210 series. However, you must also replace the rear housing seal and verify that the HOUSING REAR PART (4657201103) matches your transmission’s casting number.
Q: What torque specification should I use for the output shaft nut?
A: ZF recommends 350 Nm (258 ft-lbs) for the output flange nut on WG 210 units. Always use a new FIXING PLATE (4656301148) to prevent loosening.
Q: How do I identify a genuine ZF 4657.304.035 shaft from a counterfeit?
A: Genuine shafts have a laser-etched part number and a black oxide finish with a matte appearance. Counterfeits often show rough spline edges and lack the ZF logo stamp on the flange face.
