Overview
The ZF 2093.310.173 FLANGE SHAFT is a critical torque-transfer component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part serves as the primary interface between the transmission output and the driveline, ensuring precise rotational alignment and load distribution. The SKU 2093.310.173 is machined from high-strength alloy steel to withstand the extreme torsional stresses encountered in heavy-duty industrial applications. It sits directly within the differential housing assembly, where it connects to the 2093109029: DIFFERENTIAL and the 2093209094: DIFFERENTIAL unit, forming the backbone of the final drive system.
Symptoms of Failure
- Transmission fluid seepage near the output flange: A worn flange shaft often compromises the seal surface, causing oil to leak around the output housing during operation.
- Vibration or shudder during acceleration: When the splines or mating surfaces degrade, the shaft loses concentricity, producing noticeable driveline shudder under load.
- Intermittent gear engagement noise: A failing flange shaft can create a clunking or grinding sound as it loses proper contact with the 0750117075: TAPER ROLLER BEARING that supports its rotation.
- Reduced power transfer efficiency: Excessive play in the flange shaft leads to torque loss, often reported as sluggish response when shifting between forward and reverse.

Frequently Asked Questions
Q: Can the 2093.310.173 flange shaft be used in a ZF WG180 transmission?
A: Yes, it is compatible with WG180 models when paired with the correct differential housing (part 2093309078). However, always verify the spline engagement length and flange bolt pattern before installation.
Q: What are the first signs that this flange shaft needs replacement?
A: The earliest indicators are oil seepage around the output flange and a subtle vibration that intensifies under load. If left unchecked, these symptoms can damage the adjacent taper roller bearing (0750117075).
Q: Is this part a direct OEM replacement or aftermarket?
A: This is an OEM genuine ZF part, manufactured to the same specifications as the original equipment. It is not an aftermarket or remanufactured component.
