Overview
This genuine OEM ZF 2093.368.107 SPUR GEAR is a critical power-transfer component within the planetary gear set of the WG100, WG130, and WG131 transmission series. It functions by transmitting torque between parallel shafts, ensuring smooth and efficient gear engagement under heavy load. The SKU 2093.368.107 sits directly in the main gear train, where it meshes with adjacent pinions to maintain precise rotational synchronization. As a factory-original part, it guarantees exact fitment and metallurgical integrity, preventing premature wear in high-stress industrial applications.
Symptoms of Failure
- Whining or grinding noise during gear engagement: A worn spur gear produces a distinct high-pitched whine or metallic grinding sound, especially under load or during acceleration. This is a common long-tail search query for “ZF transmission whining noise when shifting.”
- Intermittent gear slipping or loss of torque: As the tooth profile degrades, the gear may fail to maintain positive engagement, leading to momentary power loss or “slipping” under heavy torque demands. Search terms like “WG100 gear slipping under load” are relevant here.
- Metal particles in transmission fluid: Flaking or pitting on the gear teeth generates metallic debris that contaminates the oil. This often triggers a “check transmission fluid for metal shavings” diagnostic search.
- Vibration or shuddering at specific RPMs: Uneven wear on the spur gear creates rotational imbalance, causing noticeable vibration in the driveline, particularly at cruising speeds. This aligns with queries for “ZF transmission vibration at highway speed.”

Compatibility
This spur gear is engineered specifically for the ZF WG100, WG130, and WG131 transmission models. It is also a direct replacement in certain variants of the WG180 and WG200 series where the same planetary gear set architecture is employed. Always verify the tooth count and bore dimensions against your existing gear before installation. For differential-side applications, this gear often works in tandem with the 2093109002: DIFFERENTIAL and the 2093209095: DIFFERENTIAL unit.
During rebuilds, it is common to replace this spur gear alongside the 0750117075: TAPER ROLLER BEARING which supports the shaft, and the 2093309071: DIFF.HOUSING that encloses the assembly. Proper alignment of these components is essential to prevent premature gear wear.

Frequently Asked Questions
Q: How do I know if the 2093.368.107 spur gear is compatible with my WG131 transmission?
A: Check the existing gear’s tooth count (38 teeth) and bore diameter (25.0 mm). If these match, the gear is a direct fit. Additionally, verify the module (2.75) using a gear pitch gauge to confirm compatibility.
Q: Can I replace this spur gear without removing the entire transmission?
A: In most cases, partial disassembly of the main gear housing is required. You will need to access the planetary gear set, which typically involves removing the differential cover and the 2093309071: DIFF.HOUSING. A full transmission removal is not always necessary, but professional guidance is recommended.
Q: What other parts should I replace at the same time as this spur gear?
A: It is strongly advised to replace the 0750117075: TAPER ROLLER BEARING and the 0730300820: THRUST WASHER simultaneously, as these components share the same load path and wear patterns. Also inspect the 0631100223: SPRING PIN for fatigue.
