Overview
The ZF 2094.322.035 SPUR GEAR is a precision-engineered OEM genuine component designed for the auxiliary drive train of ZF WG100, WG130, and WG131 transmissions. This gear transfers rotational force from the input shaft to the differential assembly, ensuring smooth power distribution in heavy-duty industrial applications. The SKU 2094.322.035 is manufactured to exact ZF tolerances, guaranteeing reliable meshing with mating gears and bearings. It sits directly within the gear cluster, working in tandem with the 5838109012: DIFFERENTIAL to manage torque flow under load.
Symptoms of Failure
- Whining or grinding noise during gear engagement — Worn spur gear teeth create irregular contact patterns, producing a high-pitched whine or metallic grinding sound when the transmission is under load.
- Intermittent gear slipping under heavy torque — As the gear surface wears, it can lose proper engagement with the 0750117075: TAPER ROLLER BEARING, leading to momentary power loss during acceleration or uphill operation.
- Metal particles in transmission fluid — Flaking or pitting on the spur gear teeth sheds metallic debris into the oil, often visible during routine fluid changes or filter inspections.
- Vibration through the driveline at specific RPM ranges — Unbalanced gear wear causes harmonic vibrations that can be felt in the vehicle chassis, especially between 1500-2500 RPM.

Frequently Asked Questions
Q: Can the ZF 2094.322.035 spur gear be used in a WG200 transmission?
A: Yes, it is compatible with WG200 models that utilize the same auxiliary drive configuration. However, we recommend cross-referencing your transmission serial number with ZF documentation to confirm fitment.
Q: What tools are needed to replace this spur gear?
A: Replacement requires a gear puller, torque wrench, and bearing press. You will also need to replace the 0750117075: TAPER ROLLER BEARING and inspect the 5838300626: DIFFERENTIAL HOUSING for wear during the service.
Q: How often should this gear be inspected?
A: For heavy-duty industrial applications, inspect the spur gear every 500 operating hours or during major transmission overhauls. Look for pitting, chipping, or uneven wear patterns on the tooth flanks.
