Overview
The ZF 2093.268.070 INPUT SHAFT is a critical power-transfer component engineered for the WG100, WG130, and WG131 series transmissions. As the primary torque receiver from the engine’s clutch or torque converter, this OEM genuine shaft transmits rotational force directly into the gear train. The SKU 2093.268.070 identifies a precision-ground shaft designed to maintain concentricity under heavy loads. It sits at the front of the transmission housing, interfacing with the 2093109002: DIFFERENTIAL assembly to ensure smooth power distribution. Without a properly functioning input shaft, the entire driveline loses its mechanical foundation.
Symptoms of Failure
- Transmission gear slipping under load: When the input shaft splines wear, the clutch disc can no longer maintain positive engagement, causing the transmission to slip during acceleration or hill climbs.
- Front seal oil leakage: A worn or scored input shaft surface destroys the front pump seal, leading to visible ATF drips near the bell housing—a classic “ZF input shaft leak” symptom.
- Abnormal whining or growling noise: Bearing journal wear on the 2093.268.070 shaft creates metallic chatter that intensifies with engine RPM, often misdiagnosed as a failing 0750117075: TAPER ROLLER BEARING.
- Hard shifting or gear clash: Excessive axial play in the input shaft prevents proper synchromesh alignment, resulting in grinding when engaging forward gears.

Compatibility
This input shaft is specifically engineered for the ZF WG100, WG130, and WG131 series transmissions. It also fits select variants of the WG180 and WG200 models when used with the correct 2093209095: DIFFERENTIAL carrier. The shaft is not compatible with the WG150 series without modifying the 2093309071: DIFF.HOUSING. Always verify the spline count and pilot bearing depth before installation.

Frequently Asked Questions
Q: How do I know if my ZF WG100 needs a new 2093.268.070 input shaft?
A: Measure the spline wear with a go/no-go gauge. If the spline depth is less than 1.5 mm at the root, or if the bearing journal shows a step wear of 0.1 mm or more, replacement is required.
Q: Can I reuse the old taper roller bearing with a new input shaft?
A: No. Always install a new 0750117075: TAPER ROLLER BEARING when replacing the shaft. The bearing race conforms to the old shaft’s wear pattern and will cause premature failure of the new part.
Q: Is the 2093.268.070 shaft interchangeable with the WG180 input shaft?
A: Only if you also replace the 2093309071: DIFF.HOUSING and the pilot bearing adapter. The WG180 uses a longer shaft with a different pilot depth.
