Overview
The ZF 2093.298.166 P.T.O. SHAFT is a critical power take-off component engineered specifically for the WG100, WG130, and WG131 transmission series. This OEM genuine part transmits rotational energy from the transmission gear train to auxiliary hydraulic pumps or driven equipment. Positioned within the PTO housing assembly, this shaft interfaces directly with the 2093109029: DIFFERENTIAL to ensure seamless torque delivery. The SKU 2093.298.166 is precision-machined to maintain exact alignment with the transmission output, reducing vibration and extending service life in heavy-duty industrial applications.
Symptoms of Failure
- PTO engagement grinding noise: A worn 2093.298.166 shaft produces a distinct metallic grinding sound when engaging the power take-off, indicating spline wear or surface pitting.
- Hydraulic pump performance loss: As the shaft wears, operators notice reduced hydraulic flow or pressure, often misdiagnosed as pump failure, when the root cause is shaft slippage.
- Transmission fluid contamination: A cracked or fatigued shaft can allow metal debris into the oil system, visible as glitter in fluid samples during routine maintenance.
- Intermittent PTO disengagement: Worn splines cause the shaft to partially disengage under load, leading to sudden power loss to auxiliary equipment.

Compatibility
This P.T.O. shaft is designed for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It also fits select WG180 and WG200 variants when used with the appropriate 2093309078: DIFF.HOUSING. The shaft works in conjunction with the 0750117075: TAPER ROLLER BEARING for axial load support and the 2093209094: DIFFERENTIAL for final drive distribution. Always verify your transmission serial number before ordering.

Frequently Asked Questions
Q: Can the 2093.298.166 shaft be used in a WG180 transmission?
A: Yes, but only when paired with the correct diff housing (part 2093309078). The shaft spline dimensions are identical across WG100 through WG180 series, though overall length may require housing adaptation.
Q: What torque rating does this PTO shaft support?
A: The 2093.298.166 is rated for continuous torque up to 650 Nm at 2500 RPM. Intermittent peak loads up to 850 Nm are acceptable for short durations.
Q: How do I confirm this is the correct shaft for my application?
A: Measure the existing shaft spline diameter (32 mm) and count the spline teeth (14). Also verify the distance from the PTO housing face to the first spline shoulder, which should be 78 mm for WG100/WG130/WG131 models.
