Overview
The ZF 2093.110.021 P.T.O. SHAFT is a critical power take-off component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part transmits rotational energy from the transmission’s internal gearing to auxiliary hydraulic pumps or driven equipment. Positioned within the gear train’s output cluster, the 2093.110.021 shaft ensures seamless torque delivery while maintaining precise alignment with the differential assembly. When paired with a 2093109008: DIFFERENTIAL, this shaft forms the backbone of the driveline’s power distribution system. The SKU 2093.110.021 is machined to exact OEM tolerances, guaranteeing a direct fit without modification.
Symptoms of Failure
- Intermittent P.T.O. engagement failure: Worn splines on the 2093.110.021 shaft cause the power take-off to slip or fail to engage under load, often misdiagnosed as a clutch issue.
- Metallic grinding noise from transmission housing: A worn or scored shaft surface creates audible friction against the 2093309073: DIFF.HOUSING, producing a distinct grinding sound during operation.
- Hydraulic pump output fluctuation: A damaged P.T.O. shaft cannot maintain consistent rotational speed, leading to erratic hydraulic pressure in auxiliary systems.
- Visible oil seepage near the P.T.O. mounting flange: Worn shaft seals or a scored journal surface allow transmission fluid to escape, leaving residue on the housing exterior.

Compatibility
This genuine ZF P.T.O. shaft is designed exclusively for the WG-series transmission family. Verified compatible models include:
- ZF WG100
- ZF WG130
- ZF WG131
- ZF WG180 (with adapter sleeve)
- ZF WG200 (with bearing carrier modification)
For proper installation, the shaft interfaces directly with the 2093209096: DIFFERENTIAL and requires a 0750117075: TAPER ROLLER BEARING for axial load support. Always verify housing clearance with the diff housing before assembly.

Frequently Asked Questions
Q: Can the 2093.110.021 shaft be used in a ZF WG180 without modifications?
A: The WG180 requires an adapter sleeve to accommodate the shorter spline engagement. We recommend verifying housing clearance with the diff housing before installation.
Q: What torque specification should I use for the shaft retaining nut?
A: ZF specifies 180 N·m for the retaining nut. Always replace the spring pin (part 0631100223) during reassembly to prevent loosening.
Q: How do I identify a worn shaft versus a worn taper roller bearing?
A: Check for visible spline wear or scoring on the shaft surface. If the shaft appears undamaged but axial play exceeds 0.15 mm, the taper roller bearing (0750117075) is likely the culprit.
