Overview
The ZF 2094.304.073 GEAR is a critical component engineered for the WG100, WG130, and WG131 transmission series. This precision-machined gear is situated within the transmission’s countershaft assembly, where it directly engages with the main shaft to transfer torque and facilitate smooth ratio changes. As an OEM genuine part, the SKU 2094.304.073 ensures exact fitment and metallurgical integrity, matching the original factory specifications to prevent premature wear. When installed alongside the 2094104412: MAIN SHAFT, this gear forms the backbone of the driveline’s power flow, enabling reliable operation under heavy loads.
Symptoms of Failure
When the ZF 2094.304.073 gear begins to fail, operators will notice distinct performance degradation. Whining or grinding noises during gear engagement are the most common early indicators, often caused by worn tooth profiles or pitting on the gear face. Intermittent gear slipping under load occurs when the gear’s teeth can no longer maintain positive engagement with the mating shaft, leading to power loss during acceleration. Metallic debris in the transmission oil filter signals advanced wear, as fragments from the gear’s hardened surface contaminate the lubrication system. Finally, hard shifting or gear clash during upshifts and downshifts points to misalignment or tooth damage, often requiring immediate replacement of this gear and the associated 2094106010: SHIFT SYSTEM components.

Compatibility
This genuine ZF gear is specifically designed for the WG100, WG130, and WG131 transmission models. It also shares compatibility with the WG180 and WG200 series when used in auxiliary drive configurations. The gear interfaces directly with the 2094304054: MAIN SHAFT and the 2094206001: GEARSHIFT SHAFT to ensure precise alignment. For optimal performance, always pair this gear with the correct snap rings and washers from the ZF parts catalog.

Frequently Asked Questions
Q: Can the ZF 2094.304.073 gear be used in a WG180 transmission?
A: Yes, this gear is compatible with WG180 models when used in the auxiliary drive position, though you should verify the tooth count matches your specific ratio requirements.
Q: What tools are needed to replace this gear?
A: Replacement requires a bearing puller, snap ring pliers, and a torque wrench. Always replace the 0630513070: SNAP RING and 2094306019: WASHER during installation to ensure proper axial clearance.
Q: How do I identify if my gear is worn beyond service limits?
A: Measure the tooth thickness at the pitch line. If it is below 4.2 mm, or if any pitting covers more than 10% of the tooth face, the gear must be replaced immediately to avoid catastrophic transmission failure.
