ZF 4657.304.013 OUTPUT SHAFT for WG210 | OEM Genuine Part

Overview

The ZF 4657.304.013 OUTPUT SHAFT is a critical torque-transmitting component engineered specifically for the WG 210 Series powershift transmission. This OEM genuine part transfers rotational force from the planetary gear set to the driveline flange, ensuring precise power delivery in heavy-duty industrial applications. The SKU 4657.304.013 sits directly within the rear section of the transmission housing, where it interfaces with the HOUSING REAR PART and the TRANSMISSION HOUSING to maintain concentric alignment under extreme loads. Manufactured to ZF’s exacting tolerances, this output shaft guarantees minimal backlash and long service life in demanding environments such as construction, mining, and material handling equipment.

Symptoms of Failure

• Oil leakage at the output seal area: A worn 4657.304.013 shaft surface or damaged splines can compromise the lip seal, allowing transmission fluid to weep onto the housing and bell housing. This is a common indicator of shaft wear in high-hour WG210 units.
• Gear slipping or erratic engagement: When the output shaft’s splines become stripped or fatigued, torque transfer to the driveline becomes inconsistent, causing the transmission to slip under load or hesitate during directional shifts.
• Vibration or driveline shudder: A bent or unbalanced output shaft generates noticeable low-frequency vibration through the chassis, particularly during acceleration or deceleration, signaling the need for immediate replacement.
• Metallic debris in transmission fluid: Flaking or pitting on the shaft’s bearing journals produces fine metal particles that contaminate the oil, often detected during routine filter inspections or oil analysis.

Technical Specifications

Compatibility

This output shaft is primarily designed for the ZF WG 210 Series transmission. Based on its spline geometry and bearing dimensions, it is also compatible with the following ZF power-shift models: WG 180, WG 200, WG 211, and WG 310 series. Always verify the shaft’s pilot diameter and flange bolt pattern against your specific transmission’s HOUS.FRONT SECT and rear housing alignment features. For secure installation, the CYLINDRICAL PIN (0631306792) is used to index the shaft to the planetary carrier.
