Overview
The ZF 2093.104.405 MAIN SHAFT is a critical torque-transmitting component engineered for the WG100, WG130, and WG131 transmission series. Positioned as the central rotating axis within the gear cluster, this OEM genuine part transfers engine power from the input shaft to the output flange while supporting the gear sets. The SKU 2093.104.405 is precision-machined to maintain concentricity and axial alignment, ensuring smooth power delivery under heavy loads. When installed alongside a 5838109012: DIFFERENTIAL, the main shaft forms the backbone of the drivetrain assembly, distributing rotational force to the differential gears without vibration or backlash.
Symptoms of Failure
- Transmission gear slipping under load — A worn main shaft spline or bearing journal causes the gears to lose engagement, resulting in sudden power loss during acceleration.
- Metallic grinding noise from the transmission housing — Excessive wear on the shaft surface or a damaged 0750117075: TAPER ROLLER BEARING creates audible scraping sounds that intensify with speed.
- Oil leaks near the output flange — A bent or cracked main shaft compromises the seal surface, allowing transmission fluid to escape and reducing lubrication efficiency.
- Vibration through the gearshift lever — Shaft runout or imbalance transfers harmonic oscillations to the shift mechanism, making gear selection difficult.

Compatibility
This main shaft is specifically designed for ZF WG-series transmissions with a 2.5-tonne axle capacity. Verified compatible models include WG100, WG130, and WG131. It also fits select variants of the WG180 and WG200 series when used with the correct 2093209023: DIFFERENTIAL assembly. For installations requiring a sealed housing, pair this shaft with a 5838300626: DIFFERENTIAL HOUSING to ensure proper alignment and contamination protection.

Frequently Asked Questions
Q: How do I know if the 2093.104.405 main shaft is compatible with my WG130 transmission?
A: Check the transmission serial number plate on the housing. The WG130 uses a 45mm bearing journal diameter and 21-spline output. If your unit has a different spline count, you may need the 2093.104.406 variant.
Q: Can I reuse the old taper roller bearing when replacing the main shaft?
A: No. The 0750117075: TAPER ROLLER BEARING must always be replaced with the shaft to prevent premature wear from mismatched race surfaces.
Q: What torque specification should I use for the shaft retaining nut?
A: Tighten the main shaft nut to 280 Nm (207 ft-lb) using a torque wrench, then rotate the shaft 90 degrees to align the cotter pin hole. Always install a new spring pin (0631329088) after torquing.
