ZF 4661.302.010 GEAR for WG94 | OEM Genuine Part

Overview

The ZF 4661.302.010 GEAR is a precision-machined helical gear engineered specifically for the WG 94 series transmission. This OEM genuine component sits within the intermediate shaft assembly, where it transfers torque from the input shaft to the planetary gear sets, enabling smooth ratio changes under load. The part number 4661.302.010 is laser-etched for traceability and is manufactured to ZF’s original metallurgical specifications. When installed alongside a TRANSMISSION HOUSING, this gear ensures concentric alignment and minimal backlash, which is critical for preventing premature wear in high-cycle industrial applications.

Symptoms of Failure

• Whining or howling noise during acceleration: Worn gear teeth create a distinct high-pitched sound, especially noticeable when the transmission is under load. This is a common long-tail search query for “ZF WG94 gear noise.”
• Intermittent gear slipping in higher ranges: As the 4661.302.010 gear loses tooth profile integrity, the transmission may momentarily lose torque transfer, causing a brief loss of drive power.
• Metallic debris in the transmission fluid: Flakes or silver particles found during oil changes indicate spalling on the gear flanks, which can quickly damage the HOUSING bearing surfaces.
• Hard shifting between 2nd and 3rd gear: A worn gear can cause binding in the synchronizer assembly, leading to delayed or clunky engagement.

Technical Specifications

Compatibility

This gear is a direct fit for the ZF WG94 series transmission, which includes models such as the WG180, WG200, and WG250. It is also used in certain WG150 variants produced after 2012. The 4661.302.010 gear interfaces with the countershaft and is secured by a CYLINDRICAL PIN that prevents axial movement. For proper identification, always cross-reference the TYPE PLATE on your transmission housing to confirm the exact series designation before ordering.
