Overview
The ZF 2098.310.099 P.T.O. SHAFT is a critical power take-off shaft engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part transfers 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 2098.310.099 is precision-machined to maintain concentricity and minimize vibration, directly interfacing with the 2098117002: HOUSING and the 2098301052: REAR AXLE HOUS. to form a sealed driveline assembly. Without this shaft, P.T.O. engagement becomes impossible, halting secondary system operation.
Symptoms of Failure
When the 2098.310.099 P.T.O. SHAFT wears out, operators typically notice these specific failure indicators:
- Intermittent P.T.O. engagement or disengagement – worn splines cause the shaft to slip under load, preventing consistent power take-off activation.
- Metallic grinding noise from the transmission housing – bearing surface degradation on the shaft creates audible friction against the 2098117002: HOUSING.
- Oil seepage around the P.T.O. cover – shaft seal wear allows transmission fluid to escape, often accompanied by a drop in hydraulic pressure.
- Vibration during P.T.O. operation – imbalance from shaft fatigue or torsional stress transfers through the driveline, felt in the cab or chassis.

Compatibility
This P.T.O. shaft is designed exclusively for ZF’s WG-series powershift transmissions. It directly fits the WG100, WG130, and WG131 models, commonly used in agricultural tractors and construction loaders. While the shaft is not cross-compatible with WG180 or WG200 variants due to different spline counts, it shares mounting interfaces with the 0636103300: STUD and 0637101164: HEXAGON NUT used in the P.T.O. housing assembly. Always verify transmission serial numbers before ordering.
