Overview
The ZF 2093.110.085 P.T.O. SHAFT is a critical power take-off (PTO) component engineered 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 lower gear cluster of the ZF driveline, the 2093.110.085 shaft ensures precise torque transfer and alignment. The SKU 2093.110.085 is machined to exact OEM tolerances, making it a direct replacement for worn or damaged shafts in heavy-duty industrial applications.
Symptoms of Failure
- PTO shaft vibration during engagement: When the 2093.110.085 shaft wears, excessive play develops, causing noticeable vibration when the PTO is engaged under load.
- Oil seepage from the PTO housing: A worn shaft surface or damaged seal land allows transmission fluid to leak past the seal, leaving visible oil residue on the housing exterior.
- Intermittent PTO disengagement or slipping: As the splines on the 2093.110.085 degrade, the PTO clutch can lose positive engagement, resulting in power loss to auxiliary equipment.
- Metallic debris in transmission oil: Flaking or spalling on the shaft surface introduces ferrous particles into the lubricant, detectable during routine oil changes.

Compatibility
This genuine ZF P.T.O. shaft is specifically designed for the WG100, WG130, and WG131 transmission models. It also fits select variants of the WG180 and WG200 series when used with the correct PTO adapter housing. Always verify the spline count and shaft length against your existing component before installation. The 2093.110.085 is not compatible with WG150 or WG250 transmissions without modification.
Related Components
During a PTO shaft replacement, it is standard practice to inspect and replace adjacent wear items. The 0750117075 TAPER ROLLER BEARING supports the shaft within the housing, while the 2093109029 DIFFERENTIAL and 2093209094 DIFFERENTIAL assemblies distribute torque to the axles. The 2093309078 DIFF.HOUSING encloses these rotating components and must be free of cracks for proper shaft alignment.

Frequently Asked Questions
Q: Can the 2093.110.085 P.T.O. shaft be used in a WG180 transmission?
A: Yes, the 2093.110.085 is compatible with WG180 transmissions when paired with the correct PTO adapter plate. However, you must verify the spline engagement depth and housing clearance before installation.
Q: What torque specification should I use for the shaft retaining nut?
A: The recommended tightening torque for the PTO shaft retaining nut is 120 Nm ± 10 Nm. Always apply thread-locking compound (Loctite 243 or equivalent) to prevent loosening under vibration.
Q: How do I confirm the 2093.110.085 is the correct replacement for my unit?
A: Measure the overall length (245 mm) and spline diameter (32 mm) on your existing shaft. Compare these dimensions to the specifications above. If they match, the 2093.110.085 is the correct OEM part.
