Sourced directly from Wacker Neuson, this shaft is manufactured to the exact dimensional and material specifications of the original component. Confirming your model number against the fitment list before ordering ensures a correct, hassle-free installation. Part number is the direct factory replacement for all covered variants, including 50Hz, electric start, and wheel kit configurations.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the precise 16mm diameter and 725mm length specification, ensuring correct engagement with mating components in the generator frame.
- Direct Drop-In Replacement — Matches the original mounting points and shaft geometry for straightforward installation without machining or adjustment.
- Broad Generator Series Coverage — Compatible with a wide range of Wacker Neuson portable generators across the G3.3A, G3.7A, G4.6A, G5.6A, GS4.6A, GS4.6AE, and GS5.6A families, including 50Hz and electric start variants.
- Structural Integrity Under Load — A correctly fitted axle shaft keeps wheel and frame components properly aligned; a worn or damaged shaft causes instability and uneven load distribution during transport.
- Factory Part Number Traceability — Ordering by Wacker Neuson part number 5000157902 ensures you receive the correct shaft for your specific machine variant, not a cross-referenced approximation.
The axle shaft is the structural rotating or load-bearing member that connects wheel assemblies to the generator frame, enabling the unit to be repositioned and transported safely across a worksite. At 16mm x 725mm, this shaft spans the full width of the axle assembly and carries the lateral and vertical loads placed on the generator during movement. When the shaft becomes bent, corroded, or worn at its bearing contact points, wheels may wobble, bind, or detach — making replacement essential for safe and stable machine handling.
