Overview
The ZF 2094.298.035 INPUT SHAFT is a precision-engineered component designed for the WG100, WG130, and WG131 transmission series. This OEM genuine part serves as the primary torque receiver from the engine, transferring rotational force directly into the gear train. Positioned at the front of the transmission housing, the input shaft engages with the clutch assembly and drives the countershaft through a constant-mesh gear set. The SKU 2094.298.035 is manufactured to ZF’s exacting tolerances, ensuring minimal runout and optimal load distribution during high-torque operations in commercial vehicles and industrial machinery.
Symptoms of Failure
- Audible grinding or whining noise during clutch engagement: Worn splines or bearing surfaces on the input shaft cause metal-on-metal contact, producing a distinct high-pitched sound when shifting gears.
- Oil leakage from the front transmission seal area: A damaged input shaft surface or worn seal journal allows transmission fluid to escape, often visible as drips near the bell housing.
- Hard shifting or gear clash: Excessive play in the input shaft prevents smooth synchronization, leading to delayed engagement or grinding between gears.
- Vibration through the clutch pedal or driveline: Bent or unbalanced input shafts create rhythmic oscillations that intensify under load, indicating imminent failure.

Compatibility
This input shaft is engineered for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It is also compatible with the WG180 and WG200 variants when used in conjunction with the correct 2094104412: MAIN SHAFT and 2094304054: MAIN SHAFT assemblies. For proper installation, the 2094106010: SHIFT SYSTEM and 2094206001: GEARSHIFT SHAFT must be inspected for wear. Always verify transmission serial numbers before ordering, as minor design changes exist between early and late production units.

Frequently Asked Questions
Q: Can the ZF 2094.298.035 input shaft be used in a WG180 transmission without modification?
A: Yes, the WG180 shares the same input shaft spline pattern and pilot bearing dimensions as the WG100/WG130 series. However, you must also replace the 2094104412: MAIN SHAFT if it shows wear, as mismatched shaft pairs accelerate failure.
Q: What is the typical service life of this input shaft under normal operating conditions?
A: With proper lubrication and no clutch abuse, the OEM 2094.298.035 shaft typically lasts 300,000 to 500,000 km in on-highway applications. Off-road use may reduce this interval by 40%.
Q: Do I need to replace the 0630513070: SNAP RING when installing a new input shaft?
A: Absolutely. Snap rings lose tension after removal and can dislodge, causing catastrophic internal damage. Always install a new snap ring and 2094306019: WASHER during rebuilds.
