The Wacker Neuson Main Jet is a genuine OEM component designed for the PTS4V series submersible pumps. As a factory-sourced part, it is built to the exact tolerances required for proper fuel metering through the carburetor, ensuring the engine runs at the correct air-fuel mixture under load. Verify your model number against the fitment list below before ordering to confirm compatibility with your specific PTS4V unit.
Key Features
- OEM-Calibrated Fuel Metering Orifice — Manufactured to the exact bore diameter specified by Wacker Neuson, so the carburetor delivers the correct fuel flow rate at full throttle — not an approximation.
- Direct Carburetor Drop-In — Threads directly into the carburetor main circuit bore on PTS4V models with no reworking of the fuel passages or bowl assembly.
- PTS4V Series Fitment — Confirmed fit across multiple PTS4V configurations, including units built to part configurations 5100058545, 5100058546, and 5100060386.
- Restores Full-Throttle Engine Output — A worn or clogged main jet starves the engine of fuel at high RPM, causing power loss, rough running, and stalling under load. A correctly sized replacement brings output back to spec.
- Genuine OEM Sourcing — Supplied by Wacker Neuson as an authorized replacement part, so part number 5100063226 matches the component originally installed at the factory.
The main jet is a small precision-machined orifice located inside the carburetor that controls how much fuel enters the engine at mid-to-high throttle positions. Its calibrated opening size is critical — too large and the engine runs rich, fouling the spark plug and burning excess fuel; too small or partially blocked and the engine runs lean, overheats, and loses power under demand. On a pump like the PTS4V, where sustained high-RPM operation is the norm, a correctly sized and unobstructed main jet is essential to consistent priming performance and reliable water transfer output.
