Overview
This genuine OEM ZF 2093.346.044 GEAR is a critical component engineered for the WG100, WG130, and WG131 transmission series. Positioned within the gear train assembly, this part is responsible for precise torque transfer and rotational synchronization between the input shaft and the output shaft. The SKU 2093.346.044 is machined from high-strength alloy steel to withstand the extreme loads and continuous operation typical in heavy-duty industrial applications. When installed correctly, it ensures smooth power delivery and minimizes driveline vibration. This gear is often mounted directly inside the main TRANSMISSION HOUSING, where it interfaces with the countershaft and layshaft assemblies.
Symptoms of Failure
When the ZF 2093.346.044 gear begins to fail, operators will notice distinct performance degradation. The most common symptom is gear whine or grinding noise during acceleration or deceleration, indicating worn tooth profiles. Another critical sign is intermittent gear slipping under load, where the transmission momentarily loses power delivery before re-engaging. You may also observe metal particles in the transmission fluid during routine oil changes, a direct result of gear surface spalling. Finally, difficulty engaging specific gears or a “jumping out of gear” sensation often points to excessive backlash caused by this worn component. Ignoring these signs can lead to catastrophic damage to the HOUSING and surrounding bearings.

Frequently Asked Questions
Q: How do I confirm the ZF 2093.346.044 gear is the correct replacement for my transmission?
A: Cross-reference your existing part number stamped on the gear face. This gear is standard for WG100, WG130, and WG131 models. Measure the bore diameter and tooth profile to ensure it matches your countershaft.
Q: Can I replace this gear without removing the entire transmission?
A: In most cases, yes. You can access the gear by removing the side cover and the COVER plate. However, you must drain the oil and inspect the O-RING seals for wear during reassembly.
Q: What torque specification should I use for the retaining hardware?
A: Use 45 Nm (33 ft-lbs) for the HEXAGON SCREW and 25 Nm (18 ft-lbs) for the SCREW PLUG. Always use a new O-RING to prevent leaks.
