Overview
The ZF 2093.322.038 SPUR GEAR is a critical power transmission component engineered specifically for the WG100, WG130, and WG131 series transmissions. This OEM genuine part functions as the primary gear that transfers rotational force from the input shaft to the differential assembly, ensuring smooth torque delivery under heavy loads. The SKU 2093.322.038 is precision-machined to maintain exact tooth geometry, which is essential for minimizing noise and vibration in industrial drivetrains. When installed, this spur gear meshes directly with the 2093109013: DIFFERENTIAL and works in concert with the 0750117075: TAPER ROLLER BEARING to maintain axial stability during operation.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn tooth profiles on the spur gear create irregular contact patterns, producing a distinct high-pitched sound that intensifies under load. This is a common indicator that the gear surface has fatigued.
- Intermittent gear slipping under torque: As the spur gear loses its hardened surface layer, it can no longer maintain positive engagement, causing momentary power loss when climbing grades or hauling heavy payloads.
- Metallic debris in transmission fluid: Flaking or pitting on the gear teeth sheds microscopic metal particles into the oil, which can be detected during routine fluid changes or via magnetic drain plugs.
- Vibration through the driveline at specific RPMs: Uneven wear on the spur gear creates harmonic imbalances that transmit through the 2093209096: DIFFERENTIAL and into the vehicle chassis.

Compatibility
This spur gear is designed for ZF’s medium-duty WG series transmissions. It is a direct fit for the following models: WG100, WG130, and WG131. While primarily intended for these three variants, the gear may also be compatible with the WG180 and WG200 series when used in conjunction with the correct 2093309073: DIFF.HOUSING and matching shims. Always verify tooth count and shaft spline configuration before installation.

Frequently Asked Questions
Q: Can the ZF 2093.322.038 spur gear be used in a WG200 transmission without modification?
A: The WG200 typically uses a different gear ratio set. While the physical dimensions may match, we recommend verifying the tooth count and module against your existing gear. The 2093.322.038 is factory-spec for WG100/WG130/WG131 only.
Q: What torque specification should I use when installing this spur gear?
A: The retaining nut or bolt for this gear should be torqued to 180 Nm (133 ft-lbs) when using a new 0631100223: SPRING PIN. Always consult the ZF service manual for your specific transmission model.
Q: How can I tell if my spur gear has failed without removing the transmission?
A: Listen for a cyclic whine that changes pitch with vehicle speed. Also, drain a small oil sample and look for silver glitter—this indicates gear surface fatigue. A borescope inspection through the fill plug can confirm visible tooth damage.
