ZF 2099.310.038 P.T.O. SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2099.310.038 P.T.O. SHAFT is a precision-machined power take-off shaft engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine component transmits rotational energy from the transmission’s internal gearing to auxiliary hydraulic pumps or driven equipment, ensuring seamless power delivery in heavy-duty industrial applications. As a critical link in the driveline, the shaft interfaces directly with the 2099109002: DIFFERENTIAL assembly and the 2099364014: CROWN WHEEL to maintain torque flow. The SKU 2099.310.038 is manufactured to ZF’s original tolerances, guaranteeing a direct fit without modification.

Symptoms of Failure

• Oil leaks at the P.T.O. housing seal – Worn splines or shaft surface scoring allow transmission fluid to escape, often visible as drips under the vehicle or machine.
• Intermittent gear slipping during P.T.O. engagement – A damaged shaft cannot maintain positive engagement with the 2099209001: DIFFERENTIAL gear train, causing momentary loss of power to auxiliary equipment.
• Abnormal vibration or whining noise – Bent or fatigued shafts create imbalance, leading to premature wear of the 2098309010: DIFFERENTIAL HOUSING and surrounding bearings.
• Difficulty engaging or disengaging P.T.O. – Corroded or stripped splines prevent smooth axial movement, often accompanied by grinding sounds.

Technical Specifications

Compatibility

This P.T.O. shaft is specifically designed for ZF WG-series transmissions, including the WG100, WG130, and WG131 models. It also fits select variants of the WG180 and WG200 series when used with the correct 2098309010: DIFFERENTIAL HOUSING. For applications requiring a different spline count, verify compatibility with the 2098309009: DIFFERENTIAL HOUSING or the 2098309031: AXLE BEVEL GEAR assembly. Always cross-reference your transmission serial number before ordering.
