The Wacker Neuson Fan Wheel is a genuine OEM component designed for the BH40, BH55, and BH65 series petrol breakers and the BS62-2 and BS68-2 series rammers. Sourced directly from Wacker Neuson, this part meets the exact design and dimensional requirements of the original, ensuring a correct, hassle-free installation. Compatibility extends across a wide range of tool and shoe configurations within these series, including the BH55rw, BH55rw rs, BH40rs, and Sunbelt-spec rammer variants. When it's time to restore proper engine cooling to your Wacker Neuson equipment, part is the correct replacement to reach for.
Key Features
- Genuine OEM Airflow Geometry — Manufactured to the original blade pitch and diameter specifications, so the fan wheel moves the correct volume of air across the engine under load.
- Direct-Fit Replacement — Matches the original mounting bore and hub profile, dropping straight into place on the engine shaft without modification.
- Broad Series Compatibility — Fits BH40, BH55, BH55rw, BH65 petrol breakers and BS62-2, BS68-2 rammers, including standard, rs, and Sunbelt-spec configurations.
- Protects Engine from Overheating — A worn or damaged fan wheel reduces cooling airflow, which can cause the engine to run hot, accelerate wear, and lead to premature failure. Replacing it promptly restores thermal management.
- Verified Part Number — OEM part number 5100042865 is confirmed against Wacker Neuson's own parts documentation, so you can order with confidence that you're getting the right component.
The fan wheel is a rotating component driven directly by the engine that draws cooling air over the cylinder and engine housing during operation. On air-cooled petrol breakers and rammers, it is the primary means of heat dissipation — without adequate airflow, engine temperatures rise rapidly and internal components suffer accelerated wear. A cracked, chipped, or out-of-balance fan wheel not only compromises cooling efficiency but can also introduce vibration into the drivetrain; replacing a worn fan wheel restores both thermal performance and smooth engine operation.
