Overview
The ZF 2093.110.404 P.T.O. Shaft is a critical power take-off component engineered specifically for the WG100, WG130, and WG131 transmission series. This OEM genuine part transmits rotational energy from the transmission’s internal gearing to auxiliary hydraulic pumps or driven equipment, ensuring reliable torque delivery in demanding industrial applications. The SKU 2093.110.404 sits within the rear housing assembly, directly interfacing with the 2093101016: HOUSING to maintain precise alignment and load distribution. When paired with the 2093301030: TRANSMISSION HOUSING, this shaft provides a sealed, durable interface that withstands high cyclic loads and thermal expansion.
Symptoms of Failure
- Oil leaks near the PTO mounting flange: A worn 2093.110.404 shaft can compromise the seal between the transmission housing and the PTO adapter, causing ATF or gear oil to weep externally. This often appears alongside degraded 0634801215: SEALING RING performance.
- Gear slipping or intermittent power take-off engagement: Spline wear on the shaft leads to lost rotational contact, resulting in erratic pump operation or complete loss of auxiliary drive.
- Vibration or whining noise during PTO activation: Bearing surface degradation on the shaft creates radial play, producing audible harmonics that intensify under load.
- Metal debris in transmission fluid: Flaking or pitting on the shaft’s hardened surface introduces ferrous particles into the oil, which can damage downstream components like the 0631311009: GROOVED STUD assembly.

Compatibility
This P.T.O. shaft is engineered for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It also fits select WG180 and WG200 variants when used with the correct 2093301021: GASKET and housing adapter. Always verify the spline count and shaft length against your transmission’s PTO aperture. The 2093.110.404 shaft is not compatible with WG210 or WG250 series without additional modifications. For proper identification, reference the 0730365092: TYPE PLATE on your transmission housing to confirm the exact model variant.

Frequently Asked Questions
Q: Can the 2093.110.404 shaft be used in a WG180 transmission without modifications?
A: The WG180 shares the same spline profile and mounting flange dimensions as the WG130, so direct installation is possible. However, you must replace the 0634303144: O-RING and inspect the 4475280013: SCREW PLUG for thread wear before reassembly.
Q: How do I confirm the shaft is OEM genuine and not a counterfeit?
A: Genuine ZF 2093.110.404 shafts have a laser-etched part number on the shaft body and a phosphate coating with a matte finish. Cross-reference the number with your transmission’s 0730365092: TYPE PLATE to ensure compatibility.
Q: What torque specification should I use for the retaining nut on this shaft?
A: ZF recommends 120 Nm (88 ft-lb) for the shaft retaining nut. Always use a new 0634801215: SEALING RING and apply thread locker to prevent loosening under vibration.
