Overview
The ZF 2093.304.083 DOUBLE GEAR is a critical OEM genuine component engineered for the auxiliary drive and countershaft assemblies within ZF WG-series transmissions. This double gear transfers torque between the input shaft and the differential housing, ensuring smooth power distribution under heavy load. The SKU 2093.304.083 is precision-machined to factory tolerances, making it a direct replacement for worn or damaged gears in WG100, WG130, and WG131 models. When installed alongside a 2093109002: DIFFERENTIAL, it maintains the correct gear mesh and reduces drivetrain vibration.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn gear teeth on the 2093.304.083 produce a distinct high-pitched whine, especially under load, indicating excessive backlash.
- Intermittent gear slipping or loss of drive: As the double gear wears, it can skip teeth on the mating shaft, causing sudden power loss during gear changes.
- Metal particles in transmission oil: Flaking or pitting on the gear surface releases metallic debris into the lubricant, often visible during oil changes.
- Hard shifting or grinding: A failing double gear creates resistance in the shift mechanism, making engagement of forward or reverse gears difficult.

Compatibility
This OEM genuine double gear is specifically designed for the following ZF transmission models: WG100, WG130, and WG131. It also fits select variants of the WG180 and WG200 series when used with the correct 0750117075: TAPER ROLLER BEARING and 2093209095: DIFFERENTIAL. Always verify the spline count and shaft diameter against your existing assembly. For complete rebuilds, pair this gear with a 2093309071: DIFF.HOUSING to ensure proper alignment.

Frequently Asked Questions
Q: Can the 2093.304.083 double gear be used in a WG180 transmission?
A: Yes, it is compatible with WG180 models, but you must also replace the 0750117075: TAPER ROLLER BEARING to avoid premature wear due to differing shaft tolerances.
Q: What causes premature failure of this double gear?
A: The most common cause is inadequate lubrication or contamination from debris. Always inspect the 2093309071: DIFF.HOUSING for cracks when replacing the gear.
Q: Is this an OEM ZF part or an aftermarket alternative?
A: This is an OEM genuine ZF part (SKU 2093.304.083), manufactured to the same specifications as the original factory component.
