The Wacker Neuson Main Jet #90 is a genuine OEM Main Jet #90 designed for the PT3 series self-priming centrifugal trash pump. Sourced directly from Wacker Neuson, this part carries the exact size rating and material specification required by the carburetor on PT3 pump engines. Genuine OEM designation means you're receiving the same component installed at the factory — no guesswork on sizing or fitment. Confirm compatibility with your PT3 model using the part number before ordering.
Key Features
- Exact Fuel Metering Size — Rated at #90, this jet delivers the precise fuel-to-air ratio the PT3 engine carburetor requires for consistent throttle response across the pump's operating range.
- Genuine OEM Component — Manufactured to Wacker Neuson's original specification, ensuring correct orifice diameter, thread pitch, and brass material grade — not an approximation.
- Direct Carburetor Replacement — Threads directly into the carburetor main jet port on PT3 engines with no re-jetting or adaptation; the #90 size is the stock specification for this application.
- PT3 Trash Pump Fitment — Verified fitment for the PT3 self-priming centrifugal trash pump series, a workhorse pump used in dewatering, construction site drainage, and high-volume fluid transfer.
- Protects Engine from Rich/Lean Conditions — A worn, clogged, or incorrectly sized main jet causes rough running, power loss, or hard starting; replacing it with the correct #90 OEM jet restores proper combustion and protects the engine from damage caused by running lean.
The main jet is a precisely sized brass orifice inside the carburetor that meters the volume of fuel entering the engine at mid-to-full throttle. The jet's orifice diameter — in this case, size #90 — directly controls the fuel-to-air mixture ratio; even a small deviation in sizing will cause the engine to run too rich or too lean, leading to poor performance, excessive fuel consumption, or engine damage over time. On a trash pump like the PT3, which often operates at sustained high throttle during dewatering tasks, a correctly functioning main jet is critical to maintaining consistent output and protecting the engine over long run cycles.
