The Wacker Neuson Main Jet is a genuine OEM component designed for PTS4V centrifugal trash pumps, GPS8500 and GS8.5V portable generators, and RD11V and RD880V double drum vibratory rollers. As a direct Wacker Neuson OEM part, the is manufactured to the same specification as the original, ensuring the carburetor delivers the correct air-fuel mixture under all operating conditions. Confirm your model number before ordering to ensure an exact match for your machine.
Key Features
- Calibrated Fuel Metering: — Manufactured to OEM specification with a precisely sized orifice that controls fuel flow at the correct rate for consistent engine performance across all load conditions.
- Direct Carburetor Drop-In: — Threaded to match the original carburetor bore, the 5000110086 installs in place of the worn jet without reworking or adapting the fuel circuit.
- Broad Equipment Fitment: — Compatible across multiple Wacker Neuson product families, including PTS4V trash pumps, GPS8500 and GS8.5V portable generators, and RD11V and RD880V double drum vibratory rollers.
- Fuel System Integrity: — A worn or plugged main jet causes rough running, power loss, or hard starting; replacing it with a correctly sized OEM jet restores clean combustion and full rated output.
- Fuel Circuit Safety: — An incorrect or improperly sized jet can cause an engine to run dangerously lean under load; using the genuine OEM 5000110086 eliminates that risk by maintaining the engineered fuel delivery rate.
The main jet is a small brass metering component seated inside the carburetor's main circuit. Its precisely drilled orifice controls how much fuel is drawn into the airstream when the engine is running at mid to full throttle, directly determining the air-fuel ratio the engine receives under load. When a main jet becomes clogged with varnish or debris — or is worn and out of spec — the engine will run lean, lose power, overheat, or refuse to reach full RPM, making it one of the first components to inspect during any carburetor service.
