The Wacker Neuson Tandem Hydraulic Axle is a genuine OEM component designed for G25, G50, G70, and G85 series skid-mounted mobile generators, including standard, cold weather, extended run, and custom configurations. As a factory-sourced part, the is built to Wacker Neuson's original design specifications, ensuring a direct, bolt-in replacement with no guesswork. This axle is also compatible with MGT2SD surge dual axle trailer configurations used with the G-series generator lineup. If your generator trailer is showing signs of axle wear, pulling unevenly, or exhibiting hydraulic movement issues, replacing the tandem hydraulic axle with the correct OEM part is the straightforward fix.
Key Features
- Genuine OEM Hydraulic Integrity — Manufactured to Wacker Neuson's original hydraulic pressure and load-bearing specifications for this axle assembly, not a generic approximation.
- Direct Bolt-In Replacement — Matches the original mounting configuration on G-series generator skid trailers, allowing straightforward swap-out without reworking the trailer frame.
- Broad G-Series Compatibility — Fits an extensive range of G25, G50, G70, and G85 mobile generator models across standard, cold weather, extended run, custom, and 600V Tier configurations, as well as MGT2SD dual axle trailers.
- Tandem Axle Load Distribution — The dual-axle design spreads the generator set's weight evenly across both axle points, protecting the trailer frame and improving tow stability during transport on uneven terrain.
- Roadworthiness and Transport Safety — A compromised hydraulic axle on a loaded generator trailer is a transport hazard; replacing the 5000155889 restores proper axle function and keeps the generator compliant with towing safety requirements.
The tandem hydraulic axle is the structural and mechanical foundation of the generator trailer, supporting the full weight of the skid-mounted generator set and enabling controlled, stable transport between jobsites. The hydraulic element of the axle assists in load leveling and suspension compliance, absorbing road shock that would otherwise transfer directly to the generator frame and its internal components. When the axle wears, develops hydraulic leaks, or suffers structural damage, the trailer can become unstable under tow and may cause vibration damage to the generator itself — making timely replacement critical.
