Overview
The ZF 2094.314.015 GEAR is a precision-engineered helical gear designed for the auxiliary drive and countershaft assemblies within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part transmits torque from the input shaft to the main shaft cluster, ensuring smooth power flow during gear engagement. The SKU 2094.314.015 is manufactured to ZF’s original tolerances, featuring case-hardened alloy steel for high load capacity. When installed alongside a 2094104412: MAIN SHAFT, this gear maintains precise axial alignment, reducing vibration and extending bearing life.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn gear teeth on the 2094.314.015 produce a distinct high-pitched whine that intensifies under load, often misdiagnosed as bearing noise.
- Hard shifting or gear clash: Damaged tooth profiles cause incomplete engagement, requiring excessive force to move the shift lever. This symptom frequently appears alongside a failing 2094106010: SHIFT SYSTEM.
- Metallic debris in transmission oil: Flaking or pitting on the gear face releases fine steel particles into the lubricant, visible during oil changes as a silver-gray sludge.
- Intermittent power loss in specific gears: A chipped tooth on this gear causes momentary torque interruption, particularly noticeable in 3rd and 4th gear ranges.

Compatibility
This gear is a direct replacement for ZF WG100, WG130, and WG131 series transmissions. It also fits select WG180 and WG200 variants where the auxiliary drive gear train shares identical tooth geometry. Always verify the tooth count and bore diameter against your existing part. For proper assembly, this gear mates with the 2094304054: MAIN SHAFT and is retained by the 2094206001: GEARSHIFT SHAFT assembly. Do not use in WG210 or WG250 series without cross-referencing the gear ratio.

Frequently Asked Questions
Q: Can I replace just the 2094.314.015 gear without replacing the mating shaft?
A: Yes, provided the mating 2094104412: MAIN SHAFT shows no scoring or wear. Always inspect the shaft splines and bearing journals before reassembly.
Q: What is the typical service life of this gear in a WG130 transmission?
A: Under normal operating conditions with proper lubrication, the 2094.314.015 gear lasts 8,000–12,000 hours. Premature failure often indicates misalignment or a worn 2093206001: BUSH.
Q: Does this gear require a specific snap ring for installation?
A: Yes, use the 0630513070: SNAP RING to secure the gear axially. Never reuse an old snap ring as it may lose retention force.
