Overview
This genuine OEM ZF 4108.311.086 SHAFT is a critical rotating component engineered for the WG100, WG130, and WG131 transmission series. It functions as the primary torque-transfer element within the gear train, ensuring precise alignment and smooth power delivery from the input to the output assembly. The SKU 4108.311.086 is machined to exacting tolerances to maintain gear mesh integrity and reduce vibration under heavy loads. When installed alongside the 4108101171: HOUSING, this shaft forms the core of the rotating assembly, providing the structural foundation for all planetary gear sets.
Symptoms of Failure
- Gear Slipping Under Load: A worn 4108.311.086 shaft often causes intermittent gear slippage, especially during acceleration or hill climbs, as the splines lose their grip on mating components.
- Metallic Grinding Noise from Transmission: When the shaft bearing surfaces degrade, you will hear a distinct grinding or whining sound from the transmission housing, indicating metal-on-metal contact.
- Oil Leaks Near the Output Flange: Shaft wear can compromise the seal surface, leading to persistent oil leaks around the output area. This often requires replacement of the 0501325470: SEALING RING during installation.
- Excessive Axial Play: As the shaft wears, you may detect noticeable end-play in the driveline, causing rough shifting and increased vibration at highway speeds.

Compatibility
This genuine ZF shaft is specifically designed for the WG100, WG130, and WG131 series transmissions. It is also compatible with select variants of the WG180 and WG200 models where the same shaft length and spline geometry are used. Always verify the 0730365280: TYPE PLATE on your transmission housing to confirm model designation before ordering. For accurate fluid level checks after installation, use the 0501215601: OIL LEVEL GAGE to ensure proper lubrication of the new shaft.

Frequently Asked Questions
Q: How do I know if my ZF transmission needs the 4108.311.086 shaft?
A: If you experience gear slipping, grinding noises, or oil leaks near the output flange, inspect the shaft for spline wear or surface pitting. Compare your old part number to the SKU 4108.311.086 stamped on the shaft body.
Q: Can I reuse the old sealing ring when installing this shaft?
A: No. ZF recommends always replacing the 0501325470: SEALING RING during shaft replacement to prevent future oil leaks and ensure a proper seal on the new shaft surface.
Q: Is this shaft compatible with the WG180 transmission?
A: Yes, the 4108.311.086 shaft is used in select WG180 variants. Always cross-reference your transmission’s 0730365280: TYPE PLATE to confirm compatibility before purchasing.
