Overview
The ZF 2093.298.142 GEAR is a critical power transmission component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part, identified by SKU 2093.298.142, functions as a primary drive gear within the planetary gearset, transferring torque from the input shaft to the differential assembly. Precision-ground teeth ensure smooth engagement and minimal backlash, directly influencing driveline efficiency and load-holding capacity. When installed alongside the 2093109024: DIFFERENTIAL, this gear forms the core of the final drive reduction, converting high-speed input into usable wheel torque for heavy-duty industrial applications.
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. This is a common long-tail search query for “ZF transmission whining noise when accelerating.”
- Intermittent gear slipping under heavy load: As the gear surface wears, it loses its ability to maintain positive engagement, causing momentary power loss during uphill climbs or when towing. This symptom often leads operators to search for “WG130 gear slipping under load.”
- Metallic debris in transmission fluid: Flaking or pitting on the gear face sheds microscopic metal particles into the oil, visible during routine fluid changes. This is a definitive indicator of imminent gear failure.
- Vibration in the driveline at specific RPMs: Uneven tooth wear creates harmonic imbalances, felt as a rhythmic shudder through the chassis, particularly between 1500-2000 RPM.

Compatibility
This gear is specifically designed for ZF WG-series industrial transmissions. Verified compatibility includes the following models: WG100, WG130, and WG131. It is also mechanically compatible with the WG180 and WG200 series when used in conjunction with the correct 0750117075: TAPER ROLLER BEARING and 2093209095: DIFFERENTIAL assembly. For proper installation, the gear must be paired with the 2093309071: DIFF.HOUSING to ensure correct axial alignment and oil flow. Always verify your transmission serial number before ordering.

Frequently Asked Questions
Q: Can the 2093.298.142 gear be used in a WG180 transmission without modification?
A: Yes, but only if you also replace the 0750117075: TAPER ROLLER BEARING and verify the 2093309071: DIFF.HOUSING is the correct variant for the WG180 case. The gear itself is dimensionally identical across these models.
Q: How do I confirm this is an OEM genuine part and not an aftermarket copy?
A: OEM genuine parts feature laser-etched ZF logos and the part number 2093.298.142 on the gear face. Aftermarket copies often lack the case-hardening depth, leading to premature failure within 500 operating hours.
Q: What is the typical service life of this gear under normal operating conditions?
A: With proper lubrication and load management, the 2093.298.142 gear typically lasts 8,000-12,000 hours. However, pairing it with a worn 2093109024: DIFFERENTIAL can reduce this lifespan by up to 40%.
