Overview
The ZF 2094.314.019 GEAR is a precision-machined helical gear designed for the countershaft assembly in ZF’s WG100, WG130, and WG131 heavy-duty transmissions. This OEM genuine part transfers torque from the input shaft to the main shaft, enabling smooth gear engagement under high-load conditions. As a critical component within the gear train, it directly interfaces with the 2094104412: MAIN SHAFT to synchronize rotational speeds. The SKU 2094.314.019 is manufactured to ZF’s original tolerances, ensuring exact fitment and long service life in commercial vehicle transmissions.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn gear teeth create irregular contact patterns, producing a distinct high-pitched sound that intensifies under load.
- Hard shifting or gear clash: Damaged gear flanks prevent smooth engagement with the 2094106010: SHIFT SYSTEM, causing resistance when moving the lever.
- Metallic debris in transmission oil: Flaking or pitting on the gear surface sheds microscopic metal particles, visible during oil changes as glitter-like contamination.
- Vibration through the gearshift lever: Eccentric wear on the gear hub transmits oscillations to the 2094206001: GEARSHIFT SHAFT, felt as a constant tremor in the cab.

Compatibility
This gear is engineered for ZF’s WG-series synchronized transmissions, specifically the WG100, WG130, and WG131 models found in medium-duty trucks and buses. It also fits select WG180 and WG200 variants when used in conjunction with the 2094304054: MAIN SHAFT. Always verify your transmission’s serial number against ZF’s parts catalog before ordering. The 2094.314.019 gear is not backward-compatible with older WG80 or WG90 series without shaft modification.

Frequently Asked Questions
Q: Can the 2094.314.019 gear be used in a ZF WG180 transmission?
A: Yes, but only when paired with the 2094304054: MAIN SHAFT and the correct snap ring (0630513070). The WG180 uses a slightly different countershaft offset, so verify your transmission’s serial number prefix.
Q: What causes premature wear on this gear?
A: The most common cause is insufficient oil level or using the wrong viscosity. Contaminated oil with abrasive particles accelerates pitting on the tooth flanks. Always replace the 2094306019: WASHER and snap ring when installing a new gear.
Q: How do I confirm this is the correct gear for my rebuild?
A: Measure the existing gear’s outside diameter (198.4 mm) and count 47 teeth. If your gear has 46 teeth, you need the WG80 variant. For spline compatibility, check that the bore matches the 2094104412: MAIN SHAFT diameter of 55 mm.
