Overview
This OEM genuine ZF 2093.298.028 GEAR is a critical component engineered for the WG100, WG130, and WG131 transmission series. Positioned within the final drive assembly, this gear transmits torque from the differential to the axle shafts, ensuring smooth power delivery under heavy loads. The SKU 2093.298.028 is precision-machined to ZF’s exacting tolerances, making it a direct replacement for worn or damaged gears. When paired with a properly functioning DIFFERENTIAL (5838109012), this gear maintains optimal drivetrain alignment and reduces parasitic power loss.
Symptoms of Failure
- Whining or howling noise during acceleration: A worn 2093.298.028 gear often produces a distinct metallic whine that intensifies under load, signaling tooth surface degradation.
- Vibration in the driveline at highway speeds: As gear teeth wear unevenly, vibrations transmit through the DIFFERENTIAL HOUSING (5838300626), causing noticeable shuddering in the cab.
- Intermittent gear slipping or clunking: Excessive backlash from a damaged gear can cause sudden torque disengagement, often accompanied by a loud clunk when shifting between forward and reverse.
- Metal particles in transmission fluid: Flaking or chipped gear teeth contaminate the oil, which can be detected during routine fluid changes or filter inspections.

Compatibility
This gear is specifically designed for ZF WG100, WG130, and WG131 transmissions, commonly found in medium-duty trucks, agricultural tractors, and construction loaders. It interfaces directly with the DIFFERENTIAL (2093209023) and relies on the TAPER ROLLER BEARING (0750117075) for rotational support. While not cross-compatible with WG180 or WG200 series, it may be used in select WG130 variants with matching final drive ratios. Always verify your transmission model and ratio before ordering.

Frequently Asked Questions
Q: Can I replace just the 2093.298.028 gear without replacing the differential?
A: Yes, if the mating differential gears are in good condition. However, we recommend inspecting the DIFFERENTIAL (5838109012) for wear patterns, as mismatched wear can accelerate failure.
Q: What torque specification should I use for the retaining nut on this gear?
A: ZF specifies 280–320 Nm for the shaft nut when installing this gear. Always use a new SPRING PIN (0631329088) to prevent loosening.
Q: How do I identify if my WG130 uses this gear?
A: Check the transmission tag for ratio code “A37” or measure the gear’s outer diameter (168 mm). If it matches, this part is compatible. For confirmation, compare with the AXLE BEVEL GEAR (5838300721) tooth count.
