The Wacker Neuson Nozzle Main is a genuine OEM component designed for a broad range of Wacker Neuson walk-behind trowels, vibratory plates, trash pumps, and truss screed power sections. As a factory-sourced part, the meets the original design and material specifications set by Wacker Neuson, ensuring it installs and functions exactly as intended. Compatibility extends across the CT36 and CT48 walk-behind trowel series — including standard, CE, variable speed, and electric-start variants — as well as the PT3A centrifugal trash pump, BPS 2550A vibratory plate, MPU 29A reversible plate, HPG50 and HPG100 truss screed power sections, and the HPG50A and HPG100A generators. When an exact-fit fuel system component is critical to consistent machine operation, specifying the genuine OEM part by number is the most direct path to a correct repair.
Key Features
- Genuine OEM Fuel Delivery Accuracy — Sourced directly from Wacker Neuson, this nozzle maintains the precise orifice sizing and flow characteristics engineered for the original fuel system — no retuning or adjustment required after installation.
- Direct-Fit Replacement — Engineered to the same mounting interface and connection points as the original, allowing straightforward removal and reinstallation without modification to fuel lines or fittings.
- Wide Model Coverage — A single part number covers CT36 and CT48 walk-behind trowels (standard, CE, variable speed, and electric-start builds), PT3A trash pumps, BPS 2550A vibratory plates, HPG50/HPG100 series truss screeds, and more.
- Consistent Fuel Atomization — A correctly functioning main nozzle ensures fuel is delivered at the right rate and spray pattern, supporting smooth starts, stable throttle response, and efficient combustion across the machine's operating range.
- Fuel System Safety Compliance — As a fuel-circuit component, using the genuine OEM nozzle ensures the part meets Wacker Neuson's original flow and material specifications, which is especially important on CE-certified models operating under regulatory requirements.
The main nozzle is a critical component within the carburetor's fuel metering circuit. It controls the volume and atomization of fuel delivered into the air stream during mid-range and high-speed engine operation — if the nozzle becomes clogged, worn, or dimensionally incorrect, the engine will run lean or rich, resulting in hard starting, rough idling, loss of power, or excessive fuel consumption. Replacing a faulty or damaged main nozzle with a genuine OEM part restores proper fuel delivery and brings combustion performance back to the original design standard.
