Overview
The ZF 2093.110.071 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 interface between the transmission gear train and the PTO unit, ensuring reliable mechanical power extraction for auxiliary hydraulic systems. The SKU 2093.110.071 sits within the main shaft assembly, directly engaging with the 2093109029: DIFFERENTIAL to distribute rotational force efficiently. Precision-machined from high-grade alloy steel, this shaft maintains concentric alignment under heavy loads, preventing vibration and premature wear in the driveline.
Symptoms of Failure
- PTO engagement grinding noise: A distinct metallic grinding sound when activating the PTO indicates spline wear on the 2093.110.071 shaft, often caused by insufficient lubrication or misalignment with the 0750117075: TAPER ROLLER BEARING.
- Intermittent power loss to hydraulics: If auxiliary equipment loses power intermittently, the P.T.O. shaft may have developed torsional fatigue or cracked splines, failing to transmit consistent torque from the 2093209094: DIFFERENTIAL.
- Oil seepage near PTO housing: Worn shaft seals or surface pitting on the 2093.110.071 allows transmission fluid to escape, leaving visible drips under the vehicle and reducing lubrication to the 2093309078: DIFF.HOUSING.
- Vibration during PTO operation: Excessive vibration at idle or under load suggests the shaft has become bent or unbalanced, accelerating bearing failure in the taper roller assembly.

Compatibility
This P.T.O. shaft is designed for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It also fits select variants of the WG180 and WG200 series when used with the appropriate 0631100223: SPRING PIN and 0730300820: THRUST WASHER. Always verify your transmission serial number before ordering. The shaft interfaces directly with the 4482360002: AXLE BEVEL GEAR and the 2097309085: DIFFERENTIAL AXLE in the final drive assembly.

Frequently Asked Questions
Q: Can the 2093.110.071 shaft be used in a WG180 transmission?
A: Yes, but only if the transmission is equipped with the correct PTO adapter housing. We recommend cross-referencing your existing shaft length and spline count with the specifications above. The 5838300811: THRUST WASHER must also be replaced to maintain proper end-play.
Q: How do I know if my P.T.O. shaft is failing?
A: Listen for grinding noises during PTO engagement and check for oil leaks near the housing. If you notice vibration that worsens with load, inspect the splines for wear. The 4482360001: DIFFERENTIAL BEVEL GEAR may also show signs of distress if the shaft is compromised.
Q: What torque specification is required for installation?
A: The retaining nut for the 2093.110.071 should be torqued to 180-200 Nm (133-148 lb-ft) using a new spring pin (part 0631100223). Always consult your ZF service manual for exact values, as improper torque can damage the taper roller bearing.
