The Wacker Neuson is a genuine OEM Wm270 9Hp Bfs Engine designed for the BFS series gasoline-powered floor saws, including the BFS 935B, BFS 914B, BFS 914W, BFS 940A, and BFS 940W. Sourced directly from Wacker Neuson, part number is manufactured to the same specification as the original unit installed at the factory. This engine assembly is a direct-fit replacement that slots into compatible BFS floor saw frames without modification to mounting points or drive connections. If your saw has lost power, is burning oil, or will no longer start reliably, replacing the complete engine assembly with a genuine OEM unit restores full cutting performance and gets the machine back in service.
Key Features
- Genuine OEM Engine Assembly: — Sourced directly from Wacker Neuson, this 9Hp Wm270 engine is built to the same output, torque, and displacement specs as the original — not an approximation.
- Complete Drop-In Replacement: — Mounting bolt pattern, shaft dimensions, and drive interface match the original BFS floor saw engine bay, making the swap straightforward for a qualified technician.
- Broad BFS Series Compatibility: — Fits the BFS 935B, BFS 914B, BFS 914W, BFS 940A, and BFS 940W gasoline floor saws, covering both basic and petrol-configured variants across the BFS family.
- Restores Full Blade Power: — A worn or seized engine causes inconsistent blade speed and incomplete cuts. A fresh Wm270 engine assembly delivers the consistent power output a floor saw needs to track straight and cut cleanly through concrete and asphalt.
- Fuel System Integrity: — As a complete engine unit, the 5000129960 includes matched internal fuel and ignition components, eliminating the guesswork of sourcing individual parts to rebuild a failed powerplant.
The engine is the primary power source for the BFS floor saw, converting gasoline combustion into rotational force that drives the blade spindle through the machine's belt and clutch system. At the rated 9Hp output, the Wm270 delivers the torque needed to maintain consistent blade speed under the load of cutting reinforced concrete slabs or asphalt pavement. When the engine loses compression, develops an internal oil leak, or fails to sustain idle and operating RPM, blade performance degrades immediately — cuts become ragged, the machine bogs under load, and continued use risks further drivetrain damage. Replacing the complete engine assembly with part number 5000129960 is the most direct path to restoring the saw to its designed cutting capacity.
