Overview
The ZF 2093.110.016 P.T.O. SHAFT is a critical power take-off (PTO) shaft designed for the WG100, WG130, and WG131 transmission series. This OEM genuine part transfers rotational energy from the transmission’s main drive gear to the PTO unit, enabling auxiliary equipment such as hydraulic pumps, winches, or dump bodies to operate. As a direct-fit component, the 2093.110.016 ensures precise alignment and minimal backlash within the gear train. When paired with a robust DIFFERENTIAL, this shaft maintains consistent torque delivery under heavy loads. Its splined ends and hardened steel construction are engineered to withstand the cyclic stress of frequent PTO engagement in vocational trucks and industrial machinery.
Symptoms of Failure
- PTO engagement grinding or clunking: Worn splines on the 2093.110.016 cause misalignment, producing metallic grinding noises when activating the PTO.
- Oil seepage at the PTO housing: A failing shaft can compromise the seal surface, leading to transmission fluid leaks near the PTO mounting pad.
- Intermittent PTO power loss: Excessive wear on the shaft’s drive teeth results in slipping under load, causing hydraulic pumps to lose pressure intermittently.
- Vibration during PTO operation: A bent or fatigued shaft creates harmonic vibrations that resonate through the chassis, often accompanied by a low-frequency hum.

Compatibility
This PTO shaft is factory-specified for the ZF WG100, WG130, and WG131 series transmissions. It also fits select WG180 and WG200 variants when used with the correct PTO adapter housing. The 2093.110.016 interfaces directly with the DIFFERENTIAL assembly and is secured by a SPRING PIN for positive retention. For optimal longevity, always replace the TAPER ROLLER BEARING and THRUST WASHER when servicing this shaft. The DIFF.HOUSING must be inspected for wear at the shaft bore during installation.

Frequently Asked Questions
Q: Can the 2093.110.016 shaft be used in a ZF WG180 transmission?
A: Yes, but only when the transmission is equipped with the correct PTO adapter. Always verify spline engagement depth and housing clearance before installation.
Q: What torque should be applied to the retaining bolt on this PTO shaft?
A: ZF specifies 85 Nm (63 ft-lbs) for the M16 retaining bolt. Use a new SPRING PIN to prevent loosening under vibration.
Q: How do I check if the shaft splines are worn beyond tolerance?
A: Measure the spline tooth width at the midpoint. If it measures less than 4.8 mm (0.189 in), the shaft must be replaced to avoid PTO disengagement.
