The Wacker Neuson Main Jet is a genuine OEM component designed for the WP1550VW and WP1550V single-direction vibratory plate compactors, the VPG165V vibratory plate, and the PT2V centrifugal trash pump series. As a factory-original part, it delivers the exact fuel metering characteristics required to keep the engine running at the correct air-fuel ratio under load. This jet is a direct OEM replacement, backed by Wacker Neuson's engineering specifications to ensure proper carburetor function across all compatible models. If your machine is running lean, flooding, or struggling to maintain consistent RPM, a worn or clogged main jet is often the root cause — and is the correct service replacement.
Key Features
- Calibrated Fuel Flow: — Machined to the precise orifice size needed for correct fuel delivery at full throttle, ensuring the engine hits its rated output without running rich or lean.
- Genuine OEM Origin: — Sourced directly from Wacker Neuson, this part carries the same specification as the jet installed at the factory — no guesswork on sizing or thread pitch.
- Broad Model Coverage: — Fits WP1550VW, WP1550V, and VPG165V vibratory plate compactors as well as the PT2V centrifugal trash pump, making it a useful stocking item for mixed Wacker Neuson fleets.
- Drop-In Carburetor Replacement: — Threads directly into the carburetor main jet seat with no rework required; restores proper metering without disturbing surrounding carburetor components.
- Protects Engine Health: — A correctly sized main jet prevents the lean-running conditions that accelerate cylinder and piston wear, extending engine service life on both compaction and pumping equipment.
- Fuel System Safety: — An incorrect or aftermarket jet with the wrong orifice diameter can cause dangerous over-fueling or lean-run conditions; using the genuine 5000114435 eliminates that risk.
The main jet is the primary metering component inside the carburetor, responsible for controlling the volume of fuel drawn into the engine at mid-to-full throttle. It is a small, precisely drilled brass fitting — but its orifice diameter determines the engine's entire fuel delivery curve under load. When the main jet becomes clogged with varnish deposits or wears over time, the engine will typically surge, lose power, run excessively rich with black smoke, or fail to reach full RPM. Replacing the main jet with the correct OEM-spec part restores the fuel-to-air balance the engine was designed to run on, ensuring consistent performance whether the machine is compacting soil or pumping water.
