Overview
This genuine ZF 2093.298.133 GEAR is a critical power transmission component engineered for the WG100, WG130, and WG131 series transmissions. Positioned within the final drive assembly, this gear directly engages with the 5838109012: DIFFERENTIAL to transfer torque from the countershaft to the axle output. As an OEM genuine part, the SKU 2093.298.133 ensures precise tooth geometry and metallurgical integrity, which is essential for maintaining proper backlash and load distribution under heavy industrial operation. Without this gear, the transmission cannot convert rotational speed into usable wheel torque.
Symptoms of Failure
- Whining or howling noise during acceleration: When the 2093.298.133 gear teeth become pitted or worn, they generate a distinct high-pitched whine that increases with vehicle speed, often mistaken for differential noise.
- Intermittent gear slippage under load: Worn tooth profiles cause the gear to lose positive engagement with the 2093209023: DIFFERENTIAL, resulting in momentary power loss when climbing or hauling.
- Metallic debris in transmission fluid: Flaking or spalling of the gear surface introduces fine steel particles into the oil, which can be detected during routine drain intervals and indicates imminent failure.
- Vibration through the driveline: Uneven wear on the gear’s helical cut creates cyclic vibration felt in the chassis, particularly during deceleration.

Compatibility
This gear is specifically designed for ZF WG-series powershift transmissions. It is a direct fit for the WG100, WG130, and WG131 models. It also serves as a replacement in certain WG180 and WG200 configurations when used with the correct 5838300626: DIFFERENTIAL HOUSING. Always verify the gear’s tooth count and spline interface against your existing assembly. For optimal bearing support, pair this gear with a new 0750117075: TAPER ROLLER BEARING to maintain correct preload and axial positioning.

Frequently Asked Questions
Q: Can the 2093.298.133 gear be installed without replacing the differential?
A: It is strongly recommended to inspect and, if worn, replace the mating 5838109012: DIFFERENTIAL simultaneously. Worn differential gears accelerate wear on a new gear due to mismatched tooth patterns.
Q: What is the expected service life of this gear under normal conditions?
A: With proper lubrication and load management, the OEM gear 2093.298.133 typically lasts 8,000–12,000 operating hours before requiring inspection. Heavy shock loading or contamination will reduce this interval.
Q: Does this gear require a specific break-in procedure?
A: Yes. After installation, run the transmission at 50% load for the first 2 hours, then perform a full oil change to remove any initial wear particles. This ensures the gear and 0750117075: TAPER ROLLER BEARING seat properly.
