Overview
This OEM genuine ZF 2094.346.051 GEAR is a critical component engineered for the WG100, WG130, and WG131 transmission series. It functions as a precision-machined drive gear within the main gear cluster, transferring torque from the input shaft to the countershaft assembly. The SKU 2094.346.051 ensures exact OEM fitment, eliminating guesswork during rebuilds. When installed alongside the 2094104412: MAIN SHAFT and the 2094106010: SHIFT SYSTEM, this gear ensures synchronized engagement and smooth power delivery under heavy loads.
Symptoms of Failure
When the 2094.346.051 gear wears out, operators often report gear slipping under load—a distinct loss of torque transfer during acceleration. Another common symptom is whining or grinding noise from the transmission housing, particularly in 2nd or 3rd gear. You may also notice difficulty engaging gears or a metallic clunking sound during shifts, indicating worn tooth profiles. In advanced cases, metal debris in the transmission oil pan confirms gear degradation, requiring immediate replacement to avoid cascading damage to the 2094206001: GEARSHIFT SHAFT.

Frequently Asked Questions
Q: Can I use this gear in a WG180 transmission?
A: Yes, but only when paired with the correct 2094304054: MAIN SHAFT and updated shift components. Always cross-reference your transmission serial number.
Q: What causes premature wear on the 2094.346.051 gear?
A: The most common cause is insufficient oil level or contaminated fluid. Worn 2093206001: BUSH bearings can also misalign the gear, accelerating tooth wear.
Q: Is this part interchangeable with aftermarket gears?
A: We strongly recommend OEM genuine parts. Aftermarket gears often use softer steel, leading to premature failure and potential damage to the 2094206001: GEARSHIFT SHAFT.
