The Wacker Neuson Main Jet is a genuine OEM component designed for a wide range of Wacker Neuson equipment, including VP and WP series single-direction vibratory plates, PT2 trash pumps, BFS floor saws, CT36-6 concrete trowels, and PG3 dewatering pumps. Sourced directly from Wacker Neuson, the meets the exact fuel-metering specifications required by the carburetor systems used across these machine families. This broad fitment makes it a practical stock item for dealers, rental houses, and contractors running multiple Wacker Neuson machines on the same site. Confirm your model number against the fitment list before ordering to ensure a direct match.
Key Features
- Calibrated Fuel Metering: — Precision-drilled orifice holds the correct flow rate for consistent air-fuel mixture delivery at all throttle positions.
- Genuine OEM Part: — Manufactured to Wacker Neuson's original carburetor specification — same part that came in the machine from the factory, identified by part number 5000156544.
- Wide Cross-Family Fitment: — Covers VP and WP vibratory plates, PT2 trash pumps, BFS floor saws, CT36-6 concrete trowels, and PG3 dewatering pumps in a single part number.
- Restores Full Power Output: — A worn or clogged main jet causes lean running, power loss, and hard starts; replacing it with the correct OEM jet restores rated engine performance.
- Fuel System Integrity: — Correct jet sizing is critical to avoiding over-rich or over-lean conditions that can damage engine internals — using the OEM-specified jet protects the engine long-term.
The main jet is a small but critical brass component seated inside the carburetor's float bowl. Its precisely drilled center orifice meters the volume of fuel drawn into the venturi at mid-to-full throttle, directly controlling the engine's air-fuel ratio under load. When the main jet becomes clogged with varnish or debris, the engine runs lean, loses power, surges, or refuses to rev out under load. A jet with an eroded or damaged orifice can cause over-fueling, excessive smoke, and fouled spark plugs. Replacing the 5000156544 restores accurate fuel delivery and returns the carburetor to proper operating condition.
