Overview
The ZF 2093.322.079 SPUR GEAR is a precision-machined component engineered for the power-dividing section of the WG100, WG130, and WG131 transmission families. This OEM genuine part transfers rotational force from the input shaft to the differential assembly, ensuring smooth torque distribution under heavy loads. The SKU 2093.322.079 sits directly within the gear train, meshing with the 2093109013: DIFFERENTIAL to maintain synchronized wheel speeds. Constructed from case-hardened alloy steel, it withstands high cyclic stresses in commercial vehicle applications.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn spur gear teeth create irregular contact patterns, producing a distinct high-pitched sound that intensifies under load.
- Intermittent gear slipping under torque: Excessive backlash from tooth wear causes momentary loss of drive engagement, particularly when climbing grades or hauling heavy payloads.
- Metallic debris in transmission fluid: Flaking or pitting on the gear face contaminates the oil, often visible during routine drain intervals.
- Vibration through the driveline: Uneven tooth wear generates harmonic oscillations that transmit through the 2093209096: DIFFERENTIAL housing, felt as a shudder during steady-speed cruising.

Compatibility
This spur gear is designed exclusively for ZF WG-series transmissions with a modular differential interface. Verified fitment includes the WG100, WG130, and WG131 models. It also integrates with the 2093309073: DIFF.HOUSING and the 0750117075: TAPER ROLLER BEARING which supports the gear shaft. Not compatible with WG180 or WG200 series without adapter modifications.

Frequently Asked Questions
Q: Can I replace just the spur gear without replacing the differential?
Yes, but we strongly recommend inspecting the 2093109013: DIFFERENTIAL for matching wear patterns. Mismatched gears can accelerate failure.
Q: What is the expected service life of this gear?
Under normal operating conditions with proper lubrication, the 2093.322.079 typically lasts 300,000–500,000 km. Premature failure often results from contaminated oil or bearing collapse.
Q: Does this part require special tools for installation?
Installation requires a bearing puller for the 0750117075: TAPER ROLLER BEARING and a torque wrench for the retaining nut. We recommend a ZF service manual for backlash settings.
