ZF 2098.310.101 P.T.O. SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2098.310.101 P.T.O. SHAFT is a critical power take-off component 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. Positioned within the output shaft assembly, the 2098.310.101 ensures precise torque delivery and minimal backlash. When replacing this shaft, it is common to also inspect the 2098109042: DIFFERENTIAL and the 2098309011: CROWN WHEEL for wear, as these components share the same lubrication circuit and load path.

Symptoms of Failure

• Intermittent P.T.O. engagement failure – The shaft splines wear, causing the clutch collar to slip under load, especially during cold starts.
• Metallic grinding noise from the transmission housing – Worn bearing journals on the 2098.310.101 produce a distinct scraping sound at idle.
• Oil seepage near the P.T.O. cover plate – A worn shaft seal surface allows transmission fluid to weep, often mistaken for a gasket leak.
• Vibration during P.T.O. operation – Bent or fatigued shafts create harmonic oscillations that resonate through the driveline.

Technical Specifications

Compatibility

This P.T.O. shaft is specifically designed for ZF WG-series transmissions with a power take-off adapter. Verified compatible models include:

• ZF WG100 (all variants)
• ZF WG130 (standard and high-torque)
• ZF WG131 (with integrated P.T.O. housing)
• ZF WG180 (with adapter plate modification)
• ZF WG200 (late production with 32mm spline)

For differential service, always pair this shaft with a new 2099209001: DIFFERENTIAL and inspect the 2098309010: DIFFERENTIAL HOUSING for cracks. The 2098309009: DIFFERENTIAL HOUSING is an alternative housing for WG130 units.
