The Wacker Neuson Main Jet is a genuine OEM carburetor main jet designed for a wide range of Wacker Neuson equipment, including CT36 and CT48 series walk-behind concrete power trowels, PT3A centrifugal trash pumps, GP3800 and GV5000A portable generators, BPU 3050A, BPU 3545A, BPU 3750Ats, and BPU 4045A reversible vibratory plates, BPS 2550A single-direction vibratory plates, and HPG50/HPG100 vibratory truss screed power sections. As a genuine OEM part sourced directly through Wacker Neuson's authorized parts program, is manufactured to the exact specification of the original component it replaces. Drop-in fitment means no guesswork — this jet matches the original carburetor bore size and threading for a straight swap. Whether you're servicing a trowel on a finishing crew or keeping a pump running on a dewatering site, having the correct main jet on hand gets your equipment back to full performance fast.
Key Features
- Correct Fuel Metering Spec: — Manufactured to the original carburetor jet sizing, ensuring the air/fuel mixture stays within the engine's designed operating range — not an approximation.
- Genuine OEM Part: — Sourced through Wacker Neuson's authorized parts program; this is the same jet installed at the factory, not a generic substitute.
- Broad Cross-Family Fitment: — A single jet number spans CT36 and CT48 trowels, PT3A trash pumps, GP3800 and GV5000A generators, BPU reversible vibratory plates, BPS single-direction plates, and HPG screed power sections.
- Restores Engine Performance: — A worn or clogged main jet causes rich or lean running, hard starts, and power loss; replacing with 5000110603 restores clean throttle response and steady full-load output.
- Fuel System Integrity: — Correct jet sizing prevents over-fueling that can wash cylinder walls or foul spark plugs, protecting the engine from accelerated wear during extended operation.
The main jet is a precision-metered orifice seated inside the carburetor that controls the volume of fuel delivered to the engine under mid-range and full-throttle load. Its bore diameter is calibrated to the engine's displacement and air intake volume, so even a small deviation — whether from wear, corrosion, or an incorrect replacement — shifts the fuel mixture out of spec. A jet that is partially blocked starves the engine of fuel, causing lean running, overheating, and power loss; one that is oversized or damaged floods the mixture, leading to rough running, increased fuel consumption, and hard starts. Replacing a suspect jet with the correct OEM part is one of the fastest and most cost-effective carburetor service steps available.
