The Wacker Neuson Engine Honda GX160UH2X SWX2 is a genuine OEM power unit designed for the WPU1550A and WPU1550AW series submersible pumps. As a direct Wacker Neuson OEM component, part is sourced and validated to match the original engine specification shipped on these machines — no guesswork on compatibility. This engine assembly covers both the standard WPU1550A and the WPU1550AW variants, including US-market configurations, making it the correct replacement when the original powerplant requires service or full substitution.
Key Features
- Genuine OEM Engine Assembly — Supplied directly through Wacker Neuson's authorized parts chain, ensuring the GX160UH2X SWX2 configuration matches the ignition, carburetor, and output shaft spec of the original unit.
- Drop-In Engine Replacement — Engineered to bolt directly onto the WPU1550A and WPU1550AW pump frame using the original mounting points, keeping the swap straightforward for field technicians.
- Broad WPU1550 Series Coverage — Fits WPU1550A, WPU1550A-US, WPU1550AW, and WPU1550AW-US models, covering both domestic and US-specification machines in a single part number.
- Sustained Pump Output — A correctly functioning Honda GX160UH2X SWX2 engine maintains the rated flow and head pressure of the WPU1550 pump; a worn or failed engine causes loss of pumping capacity and unplanned work stoppages.
- Fuel System Integrity — As a complete engine assembly, the unit includes fuel-side components configured to Wacker Neuson's specification, supporting safe and stable operation in demanding dewatering environments.
The Honda GX160UH2X SWX2 is a four-stroke, single-cylinder gasoline engine that serves as the primary power source for the WPU1550 series pump. It drives the pump impeller at the speed and torque required to move water efficiently across the rated head and flow range. When this engine degrades — through wear, mechanical failure, or damage — the pump loses the ability to deliver consistent performance, making a like-for-like engine replacement the most effective path back to full operation.
