Overview
The ZF 2093.310.020 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 2093.310.020 is machined from high-grade alloy steel to withstand the high torsional stresses common in heavy-duty industrial applications. It sits directly within the differential housing assembly, where it mates with the 2093109006: DIFFERENTIAL to transfer power smoothly to the axle shafts.
Symptoms of Failure
- Driveline vibration under load: A worn flange shaft causes noticeable shuddering or oscillation during acceleration, particularly at highway speeds.
- Oil seepage at the output seal: Deterioration of the shaft surface or bearing seat leads to transmission fluid leaks around the flange area.
- Intermittent gear slipping or clunking: Excessive play between the flange shaft and the 0750117075: TAPER ROLLER BEARING creates audible knocking sounds during gear changes.
- Uneven tire wear or differential noise: Misalignment from a damaged flange shaft strains the 2093209095: DIFFERENTIAL, producing a whining noise from the rear axle.

Frequently Asked Questions
Q: Can I install the ZF 2093.310.020 flange shaft without replacing the taper roller bearing?
A: It is strongly recommended to replace the 0750117075: TAPER ROLLER BEARING simultaneously, as worn bearings accelerate flange shaft wear and cause premature failure.
Q: What is the typical service life of this flange shaft in a WG130 transmission?
A: Under normal operating conditions with proper lubrication, the 2093.310.020 flange shaft lasts 150,000–200,000 km. Heavy loads or contamination can reduce this interval significantly.
Q: Does this part require special tools for installation?
A> Yes, a spline alignment tool and a bearing puller are necessary to avoid damaging the 2093309071: DIFF.HOUSING during installation. Always consult the ZF service manual for torque specifications.
