Overview
The ZF 2093.110.402 P.T.O. SHAFT (SKU: 2093.110.402) is a critical power take-off drive component engineered specifically 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 mechanical drives. Positioned within the PTO housing assembly, it interfaces directly with the 2093101052: HOUSING to ensure precise alignment and minimal backlash. The shaft’s hardened steel construction withstands high torque loads, making it indispensable for refuse trucks, concrete mixers, and other vocational vehicles that rely on continuous PTO operation.
Symptoms of Failure
- Intermittent PTO engagement failure: When the shaft splines wear, the PTO may fail to engage or disengage smoothly, causing operational delays.
- Metallic grinding noise from transmission housing: Worn bearing surfaces on the shaft produce a distinct grinding sound, especially under load, indicating imminent failure.
- Hydraulic pump performance degradation: A damaged P.T.O. shaft reduces power transfer efficiency, leading to slower hydraulic cycles or insufficient pressure.
- Oil seepage around the PTO mounting flange: Excessive shaft play can compromise the seal between the shaft and the 2093298063: TRANSMISSION HOUSING, resulting in visible fluid leaks.

Compatibility
This P.T.O. shaft is a direct fit for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It also shares mounting dimensions with the WG180 and WG200 series when used with the appropriate 2093301069: TRANSMISSION HOUSING. Always verify the PTO adapter plate configuration; the shaft requires a compatible 4475280015: SCREW PLUG for proper oil retention. For non-WG applications, consult your ZF service manual to confirm spline count and pilot bore dimensions.

Frequently Asked Questions
Q: Can the 2093.110.402 shaft be used in a ZF WG200 transmission?
A: Yes, it is mechanically compatible with the WG200 when paired with the correct 2093301069: TRANSMISSION HOUSING. However, you must verify the PTO adapter plate depth to ensure the shaft engages fully with the internal gear.
Q: What torque specification should I use for the retaining nut on this shaft?
A: ZF recommends tightening the shaft retaining nut to 120 Nm (88.5 lb-ft) using a thread-locking compound. Always replace the 0634304731: O-RING during reassembly to prevent oil leaks.
Q: How do I identify a worn P.T.O. shaft without removing the transmission?
A: Measure axial play at the PTO flange using a dial indicator. If play exceeds 0.5 mm, the shaft splines or bearing surfaces are likely worn. Listen for a rhythmic clicking sound that increases with engine RPM—this indicates spline wear.
