Overview
This OEM genuine ZF 2093.314.004 GEAR is a precision-engineered component designed for the WG100, WG130, and WG131 transmission series. Situated within the differential assembly, this gear transfers rotational force from the driveshaft to the axle shafts, enabling smooth torque distribution to the wheels. The SKU 2093.314.004 is manufactured to ZF’s exacting tolerances, ensuring minimal backlash and optimal meshing with mating gears. It works in concert with the 2093109002: DIFFERENTIAL to maintain driveline integrity under heavy loads.
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.
- Vibration through the chassis at highway speeds: Excessive wear on the 2093.314.004 gear causes imbalance in the rotating assembly, transmitting tremors to the vehicle frame.
- Intermittent gear slipping or clunking: As tooth profiles degrade, the gear may momentarily lose engagement, resulting in a sudden jolt or loss of drive power.
- Metallic debris in transmission fluid: Flakes or particles in the oil indicate advanced wear of the gear surface, often accompanied by reduced lubrication efficiency.

Compatibility
This gear is specifically engineered for ZF WG100, WG130, and WG131 transmissions. It is also compatible with select variants of the WG180 and WG200 series when used in conjunction with the 0750117075: TAPER ROLLER BEARING and the 2093209095: DIFFERENTIAL. For proper installation, the 2093309071: DIFF.HOUSING must be inspected for wear to ensure correct gear alignment.

Frequently Asked Questions
Q: How can I confirm the 2093.314.004 gear is compatible with my WG130 transmission?
Check the transmission serial number against ZF’s parts catalog. This gear is a direct fit for WG100, WG130, and WG131 models. For WG180 or WG200 variants, verify that the differential housing and bearing support match the gear’s tooth profile.
Q: What is the typical service life of this gear under normal operating conditions?
With proper lubrication and load management, the 2093.314.004 gear can exceed 500,000 km (310,000 miles). Premature failure often results from contaminated oil or misaligned differential components such as the 2093309071: DIFF.HOUSING.
Q: Should I replace the taper roller bearing at the same time as the gear?
Yes. The 0750117075: TAPER ROLLER BEARING often shows wear alongside the gear. Replacing both ensures proper preload and prevents premature failure of the new gear.
