Overview
This OEM genuine ZF 2093.304.081 GEAR is a precision-machined component engineered for the WG100, WG130, and WG131 transmission series. Positioned within the final drive assembly, this gear transfers rotational torque from the differential to the axle shafts, ensuring smooth power delivery under heavy loads. The SKU 2093.304.081 is a direct replacement part that maintains factory tolerances and material hardness. When installed alongside the 5838109012: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING, it forms the core of the drivetrain’s load-bearing gear train.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn gear teeth create irregular contact patterns, producing a distinct high-pitched whine that intensifies under load.
- Vibration in the driveline at highway speeds: Excessive backlash from a damaged 2093.304.081 gear causes rhythmic shaking felt through the chassis.
- Metallic debris in transmission fluid: Flaking or pitting on the gear surface contaminates the oil, often visible during routine drain intervals.
- Intermittent loss of power to wheels: Stripped teeth or severe wear lead to momentary slipping, especially during sharp turns or hill climbs.

Compatibility
This gear is specifically designed for ZF WG-series transmissions, including the WG100, WG130, and WG131 models. It also fits select variants of the WG180 and WG200 series when used with the corresponding 5838300626: DIFFERENTIAL HOUSING. Always verify the tooth profile and spline count against your existing assembly. For complete differential rebuilds, pair this gear with the 2093209023: DIFFERENTIAL to ensure matched wear patterns.

Frequently Asked Questions
Q: Can I use the 2093.304.081 gear in a WG180 transmission?
A: Yes, but only if you also replace the differential housing with the 5838300626: DIFFERENTIAL HOUSING to accommodate the different bearing spread. Always measure backlash after installation.
Q: How do I know if my gear is worn beyond reuse?
A: Inspect for pitting on the tooth flanks and measure backlash. If backlash exceeds 0.35 mm, or if any tooth has visible spalling, replace the gear immediately to avoid damaging the 0750117075: TAPER ROLLER BEARING.
Q: Is the 2093.304.081 supplied with a thrust washer?
A: No, this gear is sold individually. For proper installation, order the 5838300811: THRUST WASHER separately to set the correct preload.
