ZF 4616.303.048 OUTPUT SHAFT for WG65 | OEM Genuine Part

Overview

The ZF 4616.303.048 OUTPUT SHAFT is a critical rotating component engineered specifically for the WG 65 Series transmission family. This OEM genuine part transmits torque from the planetary gear set to the driveline, ensuring smooth power delivery in heavy-duty commercial vehicles and industrial machinery. Machined from high-tensile alloy steel, the shaft interfaces directly with the 4616105402: OUTPUT and the 4005303005: OUTPUT FLANGE to complete the final drive assembly. The SKU 4616.303.048 is a direct OEM replacement, guaranteeing exact fitment and load-bearing capacity for demanding applications.

Symptoms of Failure

• Transmission output seal leakage: Worn splines or a scored shaft surface cause premature seal failure, leading to fluid weeping around the output flange area.
• Vibration during gear engagement: A bent or cracked output shaft produces rhythmic driveline shudder, particularly under load between 30-50 mph.
• Intermittent gear slipping: Excessive spline wear reduces the positive lock between the shaft and the 4616101119: TRANSMISSION HOUSING, causing momentary power loss during acceleration.
• Metallic debris in transmission fluid: Flaking or spalling on the bearing journal surfaces introduces ferrous particles into the oil, detectable during routine drain intervals.

Technical Specifications

Compatibility

This output shaft is designed for the ZF WG 65 Series, but it also cross-fits select models within the WG family. Verified compatible transmissions include WG65, WG120, WG180, and WG200 series units manufactured after 2008. Always confirm the spline count and pilot bearing diameter against your existing shaft before installation. The shaft works in concert with the 0636011038: HEXAGON SCREW to secure the output flange, and replacement of the 0634313118: O-RING is recommended during any shaft service.
