Overview
The ZF 4681.303.001 OUTPUT SHAFT is a critical driveline component engineered specifically for the BP210 and BP230 series transmissions. This OEM genuine part transfers rotational torque from the planetary gear set to the vehicle’s drive shaft, ensuring smooth power delivery under heavy loads. Machined from high-tensile alloy steel, the output shaft (SKU: 4681.303.001) sits within the rear section of the transmission housing, directly interfacing with the CASE and the HOUSING REAR PART to maintain precise alignment. Without this shaft, the transmission cannot transfer engine power to the wheels, making it a non-negotiable element for operational uptime.
Symptoms of Failure
When the ZF 4681.303.001 output shaft begins to wear, operators typically notice these specific failure indicators:
- Transmission oil leaks at the rear seal: A worn shaft surface or damaged splines can compromise the rear oil seal, causing fluid to weep from the output flange area.
- Vibration during gear engagement: Excessive play between the output shaft and the HOUS.FRONT SECT creates driveline shudder, especially under load or when shifting from neutral to drive.
- Intermittent gear slipping or loss of power: Worn splines on the shaft fail to lock securely with the clutch pack, resulting in momentary power loss or delayed engagement.
- Metallic debris in transmission fluid: Flaking or pitting on the shaft surface introduces steel particles into the oil, which can be detected during routine fluid analysis.

Compatibility
This genuine ZF output shaft is designed for the BP210 and BP230 series transmissions. Based on its spline configuration and bearing dimensions, it is also compatible with the following ZF models that share the same rear housing architecture: WG180, WG200, and WG210. The shaft directly mounts into the TRANSMISSION HOUSING and works in conjunction with the HOUS.FRONT SECT and HOUSING REAR PART to form the complete driveline assembly. Always verify your transmission model tag before ordering.

Frequently Asked Questions
Q: Can the 4681.303.001 output shaft be used in a ZF WG200 transmission?
A: Yes, this shaft is mechanically compatible with WG200 models that share the BP210/BP230 housing architecture. However, always cross-reference your transmission serial number to confirm spline engagement with the HOUSING REAR PART.
Q: What tools are needed to replace this output shaft?
A: Replacement typically requires a bearing puller, torque wrench, and alignment fixture. You will also need new CAP SCREW fasteners and a fresh FIXING PLATE to secure the shaft during reassembly.
Q: How can I tell if my output shaft is OEM genuine?
A: Genuine ZF parts feature laser-etched part numbers and a uniform case-hardened finish. The 4681.303.001 shaft also includes a unique batch code on the spline end. Counterfeit shafts often lack the precise fit required by the TRANSMISSION HOUSING.
