Overview
The ZF 2093.110.070 P.T.O. SHAFT is a critical power take-off shaft 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, ensuring reliable torque delivery in heavy-duty industrial applications. Positioned within the transmission’s output housing, the shaft interfaces directly with the 2093109029: DIFFERENTIAL assembly to synchronize power distribution. The SKU 2093.110.070 is precision-machined to ZF’s original tolerances, guaranteeing seamless fitment and long service life.
Symptoms of Failure
- P.T.O. engagement grinding or clunking – Worn splines on the shaft cause misalignment during activation, producing audible metallic noises under load.
- Intermittent hydraulic pump output – A fatigued shaft may slip under torque, leading to erratic pressure drops in auxiliary systems.
- Oil seepage near the P.T.O. housing – Degraded shaft seals or surface wear allow transmission fluid to escape, visible as drips beneath the vehicle.
- Vibration during power take-off operation – Unbalanced or bent shafts generate resonance that accelerates wear on the 0750117075: TAPER ROLLER BEARING and adjacent driveline components.

Compatibility
This P.T.O. shaft is designed for ZF’s WG-series modular transmissions, specifically the WG100, WG130, and WG131 models. It also fits select variants of the WG180 and WG200 when paired with the correct 2093209094: DIFFERENTIAL housing. For proper installation, verify that the shaft’s spline profile matches your transmission’s output gear and that the 2093309078: DIFF.HOUSING is free of cracks or distortion. Always replace the associated seals and bearings during overhaul to prevent premature failure.

Frequently Asked Questions
Q: Can the 2093.110.070 shaft be used in a WG180 transmission without modification?
A: Yes, but only if the transmission is equipped with the correct differential housing (part 2093309078). Always cross-reference your transmission’s serial number with ZF’s fitment guide before installation.
Q: What torque should I apply to the retaining nut on this P.T.O. shaft?
A: ZF specifies a tightening torque of 120 Nm for the shaft’s retaining nut, followed by a 60-degree angle turn. Use a new spring pin (part 0631100223) to lock the nut after torquing.
Q: How often should the shaft be inspected for wear?
A: During every major transmission overhaul (typically every 2,500 operating hours) or immediately if you notice oil leaks or vibration. Replace the taper roller bearing (0750117075) concurrently to maintain alignment.
