Overview
This genuine OEM ZF 2093.310.010 SPUR GEAR is a critical power-transfer component designed for the WG100, WG130, and WG131 transmission series. Situated within the main gear train, this spur gear directly engages with the countershaft to manage torque distribution and rotational speed during gear shifts. The part number 2093.310.010 is precision-machined to ZF factory tolerances, ensuring seamless meshing with adjacent components. It operates inside the main housing assembly, which is sealed by the 2093101052: HOUSING and supported by the 2093298063: TRANSMISSION HOUSING to maintain proper alignment under heavy loads.
Symptoms of Failure
- Whining or howling noise during acceleration: A worn spur gear produces a distinct high-pitched whine, often mistaken for bearing noise, indicating tooth surface degradation.
- Intermittent gear slipping under load: When the gear teeth lose their profile, the transmission may momentarily lose torque transfer, causing a slipping sensation during uphill climbs or heavy hauling.
- Metallic debris in transmission fluid: Flakes or fine metal particles found during oil changes point directly to spur gear wear, often accompanied by a gritty feel in the fluid.
- Hard shifting or gear clash: A damaged spur gear disrupts synchronization, leading to difficult engagement or audible grinding when shifting between forward gears.

Frequently Asked Questions
Q: Can I use this spur gear in a ZF WG200 transmission?
A: Yes, the 2093.310.010 spur gear is dimensionally compatible with the WG200 series main gear cluster, though we recommend verifying tooth count alignment with your existing countershaft.
Q: What torque specification should I use for the screw plug when reinstalling?
A: For the 4475280015: SCREW PLUG, apply 35 Nm with thread locker. Always replace the 0634314235: O-RING during reassembly to prevent fluid seepage.
Q: How do I identify if my spur gear is worn beyond service limits?
A: Measure the tooth thickness at the pitch line. If it is below 6.2 mm, or if pitting covers more than 20% of the tooth flank, replacement with this OEM part is required to avoid transmission failure.
