Overview
The ZF 2093.110.079 P.T.O. SHAFT is a critical power take-off shaft engineered specifically for the WG100, WG130, and WG131 transmission series. This OEM genuine part serves as the primary torque transfer component, channeling engine power from the transmission housing to the differential assembly. As a precision-machined shaft, it ensures seamless engagement of auxiliary equipment while maintaining driveline stability. The SKU 2093.110.079 is manufactured to ZF’s exacting tolerances, featuring hardened steel construction that withstands high cyclic loads. When installed alongside the 2093109029 DIFFERENTIAL, this shaft forms the backbone of the gear train, enabling smooth power distribution to the wheels.
Symptoms of Failure
- P.T.O. shaft gear slipping under load – Worn splines or bearing surfaces cause intermittent power loss during heavy operation, often accompanied by a grinding noise.
- Oil leaks near the transmission output flange – Degraded shaft seals or pitted surfaces allow transmission fluid to escape, leaving visible drips beneath the vehicle.
- Vibration during P.T.O. engagement – A failing shaft creates harmonic vibrations that intensify at specific RPM ranges, indicating misalignment or bearing wear.
- Metal debris in transmission fluid – Flaking from the shaft’s hardened surface contaminates the oil, often detected during routine fluid changes.

Compatibility
This P.T.O. shaft is designed for ZF’s WG-series transmissions, specifically the WG100, WG130, and WG131 models. It also retrofits into WG180 and WG200 variants when used with the correct 0750117075 TAPER ROLLER BEARING and 2093209094 DIFFERENTIAL assembly. The shaft interfaces directly with the 2093309078 DIFF.HOUSING, ensuring proper alignment of the entire drivetrain. Always verify transmission serial numbers before installation.

Frequently Asked Questions
Q: How do I confirm the 2093.110.079 shaft fits my WG130 transmission?
A: Measure the shaft journal diameter (35 mm) and spline count (21). Cross-reference your transmission’s serial number with ZF’s compatibility chart. The shaft is also compatible with WG100 and WG131 models without modification.
Q: Can I replace this shaft without removing the differential housing?
A: Partial replacement is possible, but we recommend removing the 2093309078 DIFF.HOUSING for full access. This prevents debris contamination and allows inspection of the 0750117075 TAPER ROLLER BEARING simultaneously.
Q: What torque specification is required for the shaft retaining nut?
A: Tighten to 180 Nm using a thread-locking compound. Always replace the 0631100223 SPRING PIN during reinstallation to prevent loosening.
