Overview
The ZF 2093.298.114 CLUTCH SHAFT is a precision-machined OEM genuine component engineered for the WG100, WG130, and WG131 transmission series. This shaft serves as the critical torque-transfer interface between the clutch pack and the main drive gear set, ensuring smooth engagement and disengagement during gear changes. As a core rotating element, it sits within the transmission’s central housing, directly coupling the clutch assembly to the input shaft. The SKU 2093.298.114 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and long service life in heavy-duty industrial applications.
Symptoms of Failure
- Intermittent gear slipping under load: When the clutch shaft splines wear, the clutch pack fails to maintain full engagement, causing the transmission to slip during acceleration or uphill operation.
- Oil leaks near the bell housing: A worn shaft surface or damaged seal journal allows transmission fluid to weep past the input seal, leaving visible drips on the housing exterior.
- Abnormal grinding or whining noise: Excessive radial play in the shaft bearings produces a metallic grinding sound, especially noticeable in neutral or low gear ranges.
- Hard shifting or clutch drag: A bent or fatigued shaft prevents the clutch from fully disengaging, resulting in difficult gear selection and a persistent dragging sensation.

Compatibility
This clutch shaft is designed for the ZF WG100, WG130, and WG131 transmission models. It is also compatible with certain variants of the WG180 and WG200 series where the clutch shaft geometry matches the 21-spline input configuration. Always verify the spline count and shaft length against your existing part before installation. For differential assemblies that pair with this shaft, consider the 2093109002: DIFFERENTIAL and the 2093209095: DIFFERENTIAL units, which mount directly to the output side. The 0750117075: TAPER ROLLER BEARING supports the shaft’s axial loads, while the 2093309071: DIFF.HOUSING encloses the entire gearset.

Frequently Asked Questions
Q: Can the 2093.298.114 clutch shaft be used in a ZF WG180 transmission?
A: Yes, the shaft is compatible with WG180 models that share the 21-spline input pattern. However, always measure the overall length and bearing journal diameter to confirm fitment, as some WG180 variants use a longer shaft.
Q: What is the typical service life of this clutch shaft under normal operating conditions?
A: With proper lubrication and no contamination, the case-hardened steel shaft typically lasts 8,000–12,000 operating hours. Frequent heavy loading or misalignment can reduce this lifespan significantly.
Q: Do I need to replace the taper roller bearing when installing a new clutch shaft?
A: It is strongly recommended to replace the 0750117075: TAPER ROLLER BEARING simultaneously, as worn bearings accelerate shaft wear and can cause premature failure of the new component.
