ZF 2099.110.075 P.T.O. SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2099.110.075 P.T.O. SHAFT is a critical power take-off (PTO) component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part transmits rotational energy from the transmission’s internal gearing directly to auxiliary hydraulic pumps or driven equipment. Positioned within the rear housing of the gearbox, the shaft interfaces with the differential assembly to ensure seamless torque delivery. The SKU 2099.110.075 is a direct replacement for worn or damaged shafts, restoring full driveline functionality. For optimal system integrity, this shaft is often replaced alongside the 2099109038: DIFFERENTIAL and the 2098309008: CROWN WHEEL to prevent premature wear.

Symptoms of Failure

• PTO engagement grinding noise: A distinct metallic grinding or clattering sound when engaging the PTO indicates worn splines or bearing surfaces on the shaft.
• Oil seepage at the PTO housing: Deteriorated shaft seals or surface scoring allow transmission fluid to leak, often visible as drips near the output flange.
• Intermittent power loss to auxiliary equipment: The shaft may slip under load, causing hydraulic pumps or generators to lose RPM intermittently.
• Vibration during PTO operation: A bent or unbalanced shaft creates noticeable vibration that worsens with engine speed, potentially damaging the 2098209016: DIFFERENTIAL.

Technical Specifications

Compatibility

This PTO shaft is specifically designed for ZF WG-series transmissions. It is a direct fit for the WG100, WG130, and WG131 models. It also serves as a replacement in the WG180 and WG200 series when used with the appropriate 2095309059: DIFF.HOUSING. Always verify the spline count and shaft length against your existing unit before installation. For complete driveline restoration, consider pairing this shaft with the 2095309081: DIFFERENTIAL AXLE to ensure concentric alignment.
