Overview
The ZF 2093.298.144 GEAR is a critical power transmission component engineered specifically for the WG100, WG130, and WG131 series transmissions. This OEM genuine part functions as a primary drive gear within the planetary gear set, transferring torque from the input shaft to the differential assembly. The SKU 2093.298.144 is precision-machined to maintain exact tooth geometry, ensuring smooth engagement and minimal backlash during high-load operations. When installed correctly, this gear works in concert with the 2093109001: DIFFERENTIAL to distribute power evenly across the axle system.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn gear teeth create uneven contact patterns, producing a distinct high-pitched sound that intensifies under load.
- Intermittent gear slippage in forward gears: As the 2093.298.144 gear loses its hardened surface, it fails to maintain positive engagement, causing momentary power loss.
- Metallic debris in transmission fluid: Flaking or spalling of the gear surface contaminates the oil, often visible during routine drain intervals.
- Vibration through the driveline at cruising speed: Excessive wear on the gear’s tooth profile induces harmonic vibrations that resonate through the chassis.

Compatibility
This genuine ZF gear is designed for the WG100, WG130, and WG131 transmission models commonly found in medium-duty commercial vehicles and agricultural machinery. It also serves as a direct replacement in certain WG180 and WG200 variants where the differential housing configuration matches. For proper installation, always pair this gear with a new 0750117075: TAPER ROLLER BEARING to maintain correct preload and shaft alignment. The gear interfaces directly with the 2093209095: DIFFERENTIAL and must be housed within the 2093309071: DIFF.HOUSING for proper oil circulation.

Frequently Asked Questions
Q: How can I confirm that the 2093.298.144 gear is compatible with my WG130 transmission?
A: Verify the gear’s tooth count (29 teeth) and module (4.5 mm) against your existing part. The 2093.298.144 is a direct fit for WG100, WG130, and WG131 models; for WG180 or WG200 units, measure the differential housing bore diameter to ensure proper clearance.
Q: What other parts should I replace when installing this gear?
A: It is strongly recommended to replace the 0750117075: TAPER ROLLER BEARING and the 0730300820: THRUST WASHER simultaneously, as these components wear together and affect gear mesh alignment.
Q: Does this gear require special lubrication after installation?
A: Use only ZF-approved GL-5 or GL-6 grade gear oil with a viscosity of SAE 80W-90. The 2093.298.144 gear’s hardened surface relies on extreme-pressure additives for longevity.
