Overview
This genuine ZF 2093.304.065 GEAR is a precision-machined component engineered for the WG100, WG130, and WG131 transmission series. Positioned within the intermediate shaft assembly, this gear transfers torque from the input shaft to the output shaft, enabling smooth ratio changes under heavy load. The SKU 2093.304.065 is manufactured to OEM tolerances, ensuring exact tooth geometry and surface hardness for minimal noise and vibration. When installed alongside the 2093101052: HOUSING, this gear forms the core of the power delivery path. It also interfaces directly with the 2093298063: TRANSMISSION HOUSING to maintain correct shaft alignment under high-torque conditions.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn gear teeth on the 2093.304.065 produce a distinct high-pitched sound, especially in lower gears. This is a common long-tail search query for “ZF transmission whining noise WG100.”
- Intermittent gear slippage under load: As the gear surface wears, it loses tooth engagement, causing the transmission to momentarily lose drive power. This symptom often triggers searches for “ZF WG130 gear slipping repair.”
- Metal particles in transmission fluid: Spalling or pitting on the gear face releases fine metallic debris into the oil. This is frequently searched as “metal shavings in ZF transmission oil.”
- Hard shifting or delayed engagement: Excessive backlash from a worn gear forces the synchronizers to work harder, leading to rough gear changes. This aligns with queries like “ZF WG131 hard shifting fix.”

Compatibility
This gear is specifically designed for ZF’s WG-series industrial transmissions. It is a direct fit for the following models: WG100, WG130, and WG131. It may also be compatible with the WG180 and WG200 series when used in the intermediate shaft position, though verification of shaft diameter and spline count is recommended. The gear works in concert with the 2093301069: TRANSMISSION HOUSING to ensure correct axial play. For sealing the assembly, use the 4475280015: SCREW PLUG to prevent oil leakage from the housing ports.

Frequently Asked Questions
Q: How do I know if the 2093.304.065 gear is worn out?
A: Listen for a persistent whining noise that changes pitch with vehicle speed. Also check the transmission oil for metallic glitter; this indicates gear surface fatigue. A visual inspection of the tooth flanks for pitting or step wear is definitive.
Q: Can I replace this gear without removing the entire transmission?
A: In most WG100/WG130 applications, you can access the gear by removing the side cover and the 2093301033: COVER. However, you must also replace the 0634314235: O-RING and the 0636015073: HEXAGON SCREW to ensure a proper seal.
Q: What is the torque specification for the screw plug near this gear?
A: The 4475280150: SCREW PLUG should be tightened to 35 Nm. Always use a new 0634304731: O-RING during reinstallation to prevent oil seepage.
