ZF 4616.308.013 GEAR for WG65 | OEM Genuine Part

Overview

The ZF 4616.308.013 GEAR is a critical power transmission component engineered specifically for the WG 65 series of heavy-duty industrial transmissions. This OEM genuine part functions as an intermediate or output gear, precisely meshing with adjacent shafts to transfer torque and maintain rotational synchronization within the gear train. The SKU 4616.308.013 is manufactured to ZF’s exacting tolerances, ensuring minimal backlash and optimal load distribution during high-stress operations. When installed alongside the TRANSMISSION HOUSING, this gear provides the structural integrity required for prolonged service life in demanding applications such as construction machinery and agricultural equipment.

Symptoms of Failure

• Audible gear whine or grinding noise during acceleration or deceleration, often indicating worn tooth profiles or pitting on the 4616.308.013 gear surface.
• Intermittent gear slipping under load, particularly when shifting between forward and reverse in WG65 transmissions, signaling excessive clearance or tooth deformation.
• Metallic debris in transmission oil discovered during routine filter changes, a classic sign of spalling or chipping on the gear teeth that requires immediate replacement.
• Vibration through the driveline at specific RPM ranges, caused by uneven wear patterns that disrupt the balanced rotation of the gear assembly.

Technical Specifications

Compatibility

This 4616.308.013 gear is primarily designed for the ZF WG 65 series transmission family. Based on its part number structure and gear geometry, it is also compatible with select models in the WG180 and WG200 series that share the same modular gear train architecture. The part fits directly into transmissions used in wheel loaders, forklifts, and mobile cranes where the WG65 gearbox is standard. For proper installation, always pair this gear with the correct HEXAGON SCREW and HEXAGON SCREW fasteners to secure the assembly. Additionally, the HEXAGON SCREW is required for mounting the gear to its shaft hub.
