Overview
The ZF 2093.110.003 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 rotational link between the transmission’s internal gearing and the PTO unit, transferring engine torque to auxiliary hydraulic pumps or driven equipment. As a precision-machined component, the SKU 2093.110.003 sits within the transmission’s output housing, engaging directly with the DIFFERENTIAL assembly to ensure seamless power distribution. Its splined design and hardened steel construction guarantee reliable engagement under high-torque conditions, making it indispensable for heavy-duty industrial applications.
Symptoms of Failure
- Intermittent PTO engagement failure: When the shaft wears, operators may experience erratic power take-off activation, often accompanied by grinding noises during engagement.
- Transmission oil contamination: A worn 2093.110.003 shaft can shed metallic debris into the gearbox oil, visible as glittering particles during routine fluid checks.
- Vibration at the PTO housing: Excessive axial play in the shaft causes noticeable vibration through the driveline, particularly under load at low RPM.
- Premature bearing wear: A failing shaft places abnormal stress on the adjacent TAPER ROLLER BEARING, leading to early failure and potential housing damage.

Compatibility
This P.T.O. shaft is designed for ZF’s WG-series industrial transmissions, specifically the WG100, WG130, and WG131 models. It also fits select variants of the WG180 and WG200 series when used with the correct DIFF.HOUSING. The part is not interchangeable with earlier WG50 or WG80 series without adapter modifications. For proper installation, verify that the shaft’s spline profile matches your transmission’s internal DIFFERENTIAL gear set.

Frequently Asked Questions
Q: How do I confirm the 2093.110.003 shaft fits my WG130 transmission?
Measure the existing shaft’s spline diameter and count the spline teeth. The 2093.110.003 uses a 14-tooth involute spline with a 32mm major diameter. Cross-reference your transmission’s serial number with ZF’s compatibility chart for absolute certainty.
Q: Can I replace only the shaft without replacing the taper roller bearing?
It is strongly recommended to replace the TAPER ROLLER BEARING simultaneously. Worn shafts often damage bearing raceways, and reusing old bearings can lead to premature failure of the new shaft within 500 operating hours.
Q: What torque specification is required for the shaft retaining nut?
ZF specifies 180 Nm (133 ft-lbs) for the retaining nut on WG100/WG130 series transmissions. Always use a new spring pin (0631100223) after torquing to prevent nut loosening during operation.
