Overview
The ZF 2093.210.023 CLUTCH SHAFT is a precision-machined component designed to transfer torque from the clutch assembly directly into the transmission gear train. Positioned within the input section of the ZF WG100, WG130, and WG131 transmissions, this OEM genuine part ensures smooth engagement and disengagement of power flow. The SKU 2093.210.023 is engineered to exact factory tolerances, making it a direct replacement for worn or damaged shafts in heavy-duty drivelines. This shaft works in concert with the 2093109029: DIFFERENTIAL to distribute power efficiently to the axles.
Symptoms of Failure
- Clutch drag or incomplete disengagement: A worn clutch shaft can cause the clutch to remain partially engaged, leading to hard shifting and gear grinding during gear changes.
- Transmission oil leaks at the input shaft seal: Grooves or pitting on the shaft surface damage the seal, resulting in visible oil drips under the bell housing.
- Vibration or chatter during clutch engagement: Excessive play in the shaft splines creates a rhythmic shudder when taking off from a stop.
- Gear slipping under load: A damaged shaft cannot maintain proper alignment, causing the transmission to slip out of gear during acceleration or hill climbing.

Compatibility
This clutch shaft is specifically designed for ZF heavy-duty transmissions in the WG series. It is a direct fit for the following models: WG100, WG130, and WG131. These transmissions are commonly found in municipal trucks, refuse vehicles, and medium-duty construction equipment. For proper assembly, this shaft must be paired with the 0750117075: TAPER ROLLER BEARING which supports the shaft’s radial load, and the 2093209094: DIFFERENTIAL which receives the final drive torque. The 2093309078: DIFF.HOUSING encloses the entire differential assembly and must be inspected for cracks during clutch shaft replacement.

Frequently Asked Questions
Q: Can the ZF 2093.210.023 clutch shaft be used in a WG180 transmission?
A: No. This shaft is engineered exclusively for the WG100, WG130, and WG131 models. Using it in a WG180 will result in improper spline engagement and potential transmission damage.
Q: What is the typical service interval for replacing this clutch shaft?
A: There is no fixed interval. Replacement is driven by symptoms such as oil leaks or shifting difficulty. In severe-duty applications, inspect the shaft every 200,000 miles or during a full transmission rebuild.
Q: Do I need to replace the taper roller bearing at the same time?
A: Yes. It is strongly recommended to install a new 0750117075: TAPER ROLLER BEARING whenever the clutch shaft is replaced, as the bearing race often suffers wear from the damaged shaft.
