Overview
The ZF 2093.322.031 SPUR GEAR is a precision-machined helical gear designed to transfer torque between parallel shafts within the auxiliary drive section of ZF WG100, WG130, and WG131 transmissions. This OEM genuine part (SKU: 2093.322.031) sits directly on the countershaft assembly, meshing with the main drive gear to enable smooth power flow during low-range and high-range operation. As a critical component in the gear train, it ensures consistent rotational speed and load distribution. For proper sealing and alignment, this spur gear is often installed alongside the 2093101052 HOUSING and the 2093298063 TRANSMISSION HOUSING to maintain structural integrity.
Symptoms of Failure
- Whining or grinding noise during gear engagement: Worn teeth on the spur gear produce a distinct metallic whine, especially under load in WG100/WG130 units.
- Intermittent gear slipping in low range: As the gear profile wears, the transmission may momentarily lose torque transfer, causing a slipping sensation during acceleration.
- Metal particles in transmission fluid: Flaking or pitting on the gear surface contaminates the oil, often visible as glittery debris during routine drain intervals.
- Vibration through the shift lever: Uneven tooth wear creates rotational imbalance, transmitting noticeable vibration into the cab during highway speeds.

Compatibility
This spur gear is engineered exclusively for ZF off-highway and industrial transmissions. It is a direct fit for the following models: WG100, WG130, and WG131. It also serves as a replacement part in certain WG180 and WG200 variants where the auxiliary drive configuration matches the 37-tooth gear ratio. Always verify the tooth count and bore diameter against your existing gear. When replacing this component, we recommend inspecting the 2093301069 TRANSMISSION HOUSING for cracks and replacing the 4475280015 SCREW PLUG to prevent fluid leaks.

Frequently Asked Questions
Q: Can the ZF 2093.322.031 spur gear be used in a WG200 transmission?
A: Yes, it is compatible with WG200 models that share the same auxiliary drive configuration, but always confirm the tooth count (37 teeth) and bore diameter (45 mm) against your existing gear before installation.
Q: What torque specification should I use for the retaining nut on this gear?
A: The recommended tightening torque for the shaft retaining nut is 180 Nm (133 ft-lb) for WG100/WG130 series. Always apply thread locker to prevent loosening during operation.
Q: How often should this spur gear be inspected?
A: We recommend visual inspection every 500 operating hours or during major transmission overhauls. Look for pitting, spalling, or uneven wear patterns on the tooth flanks.
