ZF 4616.303.116 OUTPUT SHAFT for WG65 | OEM Genuine Part

Overview

The ZF 4616.303.116 OUTPUT SHAFT is a critical driveline component engineered specifically for the WG 65 Series transmission. This OEM genuine part transmits rotational torque from the transmission’s planetary gearset to the output flange, directly influencing vehicle propulsion and load-handling stability. Machined from high-strength alloy steel, the shaft interfaces with the OUTPUT assembly and the OUTPUT FLANGE to ensure precise power delivery. The SKU 4616.303.116 guarantees exact fitment and OEM-grade durability for heavy-duty applications.

Symptoms of Failure

• Transmission oil leaks at the rear seal: A worn output shaft can damage the seal, causing fluid to drip near the driveline connection. This often appears as “ZF WG65 rear seal leak” in service logs.
• Vibration or shudder during acceleration: Excessive play in the shaft splines or bearing surfaces leads to driveline shudder, especially under load. Technicians may report “output shaft vibration WG65.”
• Gear engagement delay or slipping: When the shaft’s splines wear, torque transfer becomes inconsistent, causing delayed engagement or intermittent slipping in forward gears.
• Metallic debris in transmission fluid: Flaking or pitting on the shaft surface introduces ferrous particles into the oil, detectable during routine filter changes.

Technical Specifications

Compatibility

This output shaft is designed for the ZF WG 65 Series transmission family. Based on its spline geometry and load rating, it is also compatible with the following ZF models: WG180, WG200, and WG250. Always verify fitment by cross-referencing your transmission’s serial number with the SKU 4616.303.116. The shaft works in conjunction with the TRANSMISSION HOUSING and is secured using HEXAGON SCREW fasteners.
