Overview
The ZF 2093.322.003 SPUR GEAR is a critical power transmission component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part functions as a primary drive gear within the countershaft assembly, transferring rotational force from the input shaft to the differential system. The SKU 2093.322.003 is precision-machined to maintain exact tooth geometry, ensuring smooth engagement with mating gears under heavy torque loads. When installed alongside a 5838109012: DIFFERENTIAL, this spur gear optimizes power delivery and reduces drivetrain noise in industrial applications.
Symptoms of Failure
- Whining or grinding noise during acceleration: Worn teeth on the 2093.322.003 produce a distinct metallic whine that intensifies under load, often misdiagnosed as a bearing issue. This is a common search query for “ZF transmission whining noise when accelerating.”
- Intermittent gear slippage under heavy load: As the spur gear teeth wear unevenly, the transmission may momentarily lose torque transfer, causing a “slipping gear” sensation. This symptom frequently appears alongside a failing 0750117075: TAPER ROLLER BEARING.
- Metal particles in transmission fluid: Flaking or pitting on the gear surface deposits metallic debris into the oil, detectable during routine fluid changes. This is a critical “ZF transmission metal shavings” warning sign.
- Vibration at specific RPM ranges: Imbalanced gear wear causes harmonic vibrations that resonate through the driveline, particularly between 1500-2000 RPM.

Compatibility
This spur gear is specifically designed for ZF WG-series transmissions, including the WG100, WG130, and WG131 models. It also fits select WG180 and WG200 variants produced between 1998-2012. The 2093.322.003 interfaces directly with the 2093209023: DIFFERENTIAL assembly and requires proper alignment with the 5838300626: DIFFERENTIAL HOUSING for correct mesh depth. Always verify your transmission serial number before ordering, as late-model WG131 units may use a revised tooth profile.

Frequently Asked Questions
Q: Can the 2093.322.003 spur gear be installed without replacing the taper roller bearing?
A: It is strongly recommended to replace the 0750117075: TAPER ROLLER BEARING simultaneously, as worn bearings accelerate gear tooth wear and cause misalignment.
Q: What is the expected service life of this spur gear in a WG130 transmission?
A: Under normal operating conditions with proper lubrication, the 2093.322.003 typically lasts 8,000-12,000 hours. Heavy shock loads or contaminated oil can reduce this significantly.
Q: Does this gear require special tools for installation?
A> Yes, a hydraulic press and gear puller are needed to remove the old gear and seat the new one without damaging the shaft or the 5838300626: DIFFERENTIAL HOUSING bore.
