The Wacker Neuson Hub & Drum is a genuine OEM component designed for the G100, G120, G150, G180, G230, and G240 series portable generators, as well as MGT3.1S and MGT4S trailer configurations. As a direct factory replacement, this part is manufactured to the same tolerances and specifications as the original, ensuring correct installation on your Wacker Neuson generator unit. It also covers a broad range of Tier 3, Tier 4, and Tier 4 Final variants across standard, cold weather, and custom configurations, making it the right choice for a wide variety of G-series fleet setups. Confirm your model and machine number against the fitment list before ordering to ensure this is the correct part for your unit.
Key Features
- Genuine OEM Construction: Manufactured to Wacker Neuson's original material and dimensional specifications, delivering the same structural integrity as the hub and drum assembly your generator left the factory with.
- Drop-In Installation: Engineered as a direct replacement that mounts to the existing axle and brake hardware without alteration, maintaining the original brake geometry and drum-to-shoe clearance.
- Broad G-Series and MGT Trailer Coverage: Compatible with G100, G120, G150, G180, G230, and G240 generator models across multiple Tier ratings, plus MGT3.1S and MGT4S dual-axle trailer configurations.
- Braking System Integrity: A worn or out-of-round drum compromises braking efficiency during generator towing — replacing with an OEM hub and drum assembly restores correct shoe contact, stopping distance, and trailer control.
- Towing Safety Compliance: The hub and drum is a load-bearing, safety-critical component in the trailer brake system. Using a genuine OEM part ensures the assembly meets the rated brake capacity for 5,200 lb and 6,000 lb axle configurations.
The hub and drum assembly is a core component of the wheel-end braking system on generator trailers. The hub houses the wheel bearings and provides the mounting interface for the wheel, while the drum acts as the friction surface against which the brake shoes press to slow or stop the trailer during towing. When the drum surface becomes grooved, scored, or worn beyond its serviceable thickness, braking force drops significantly and shoe wear accelerates — both of which compromise safe trailer handling. Replacing a degraded hub and drum assembly restores full braking capacity and protects the surrounding wheel-end components from secondary damage.
