Overview
The ZF 2093.314.008 SHAFT is a precision-machined component designed for the internal gear train of ZF WG100, WG130, and WG131 transmissions. This OEM genuine part serves as the primary torque-transfer element between the input shaft and the differential assembly, ensuring smooth power delivery under heavy loads. The SKU 2093.314.008 is engineered to exact OEM tolerances, reducing vibration and wear in the drivetrain. It sits directly within the transmission housing, interfacing with the 2093109002: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING to maintain axial alignment and rotational stability.
Symptoms of Failure
When the ZF 2093.314.008 shaft begins to wear, operators often notice distinct failure indicators. Transmission gear slipping under load is a primary symptom, as the shaft loses its ability to maintain constant engagement with mating gears. Excessive driveline vibration at highway speeds frequently occurs due to shaft imbalance or surface pitting. Metallic grinding noises during gear changes indicate advanced wear on the shaft splines or bearing journals. Oil leaks near the transmission output flange can also develop if the shaft seal surface becomes scored or corroded.

Compatibility
This genuine ZF shaft is specifically engineered for the WG100, WG130, and WG131 transmission series. It is a direct replacement for units operating in medium-duty trucks, agricultural tractors, and construction loaders. The part also integrates with the 2093209095: DIFFERENTIAL and the 2093309071: DIFF.HOUSING in the same assembly. While primarily for WG100/WG130/WG131, it may also fit select WG180 and WG200 variants with identical shaft dimensions—always verify with your OEM parts catalog before installation.

Frequently Asked Questions
Q: How do I confirm the ZF 2093.314.008 shaft fits my transmission?
A: Verify your transmission model plate. This shaft is designed for WG100, WG130, and WG131 series. Measure the shaft length (312 mm) and spline count (24) to cross-check against your existing part.
Q: Can I replace this shaft without removing the entire transmission?
A: In most cases, partial disassembly of the differential housing is required. You will need to remove the 2093309071: DIFF.HOUSING and the 0750117075: TAPER ROLLER BEARING to access the shaft. Full transmission removal is recommended for complete inspection.
Q: What other parts should I replace when installing this shaft?
A: It is best practice to replace the 0631100223: SPRING PIN and both 0730300820: THRUST WASHER and 5838300811: THRUST WASHER simultaneously to prevent premature wear on the new shaft.
