ZF 4616.305.046 SPUR GEAR for WG65 | OEM Genuine Part

Overview

The ZF 4616.305.046 SPUR GEAR is a critical power transmission component engineered specifically for the WG 65 Series transmission. This genuine OEM part, identified by SKU 4616.305.046, sits within the planetary gear set assembly, where it meshes directly with the sun gear and ring gear to transfer torque from the input shaft to the output shaft. By precisely managing gear ratios, this spur gear ensures smooth acceleration, consistent load handling, and efficient power flow in heavy-duty industrial applications. When installed alongside the 4616105415: OUTPUT and the 4616303144: OUTPUT FLANGE, it forms the backbone of the drivetrain’s final drive stage.

Symptoms of Failure

When the 4616.305.046 spur gear begins to wear, operators often notice distinct performance issues. Look for these specific failure symptoms to catch problems early:

• Gear whining or grinding noise during acceleration: Worn teeth create uneven contact, producing a high-pitched whine or metallic grinding sound that intensifies under load.
• Intermittent gear slipping under heavy torque: Damaged tooth profiles cause the gear to lose engagement, resulting in sudden power loss or jerking movements during operation.
• Metallic debris in transmission fluid: As the spur gear wears, small metal particles contaminate the oil, often visible during routine fluid checks or filter inspections.
• Vibration through the transmission housing: Imbalanced gear rotation transmits excessive vibration to the 4616101094: TRANSMISSION HOUSING, which can be felt as a shudder in the vehicle chassis.

Technical Specifications

Compatibility

This ZF 4616.305.046 spur gear is designed for the WG 65 Series transmission family. Based on its gear geometry and spline configuration, it is compatible with the following ZF models that share the same planetary gear set architecture: WG65, WG80, WG100, WG120, WG150, and WG180. For proper installation, always pair this gear with the correct 0636011038: HEXAGON SCREW to secure the gear to the shaft. Additionally, verify that the 0636011118: HEXAGON SCREW and 0636016015: HEXAGON SCREW are used for mounting adjacent components to prevent misalignment.
