The Wacker Neuson Main Jet is a genuine OEM component designed for the BPU 3050A, BPU 3750Ats, BPU 4045A, PT3A, and PT3A(I) series machines. As a direct factory replacement, this part meets the exact specifications Wacker Neuson engineers built into these units at the time of manufacture. The fits multiple BPU reversible vibratory plate compactors as well as PT3A and PT3A(I) self-priming trash pumps, making it a versatile service item to have on hand. Confirm your model number before ordering to ensure accurate fitment.
Key Features
- Calibrated Fuel Metering: — Manufactured to the exact orifice specification required to maintain the correct air-to-fuel ratio in the carburetor — critical for consistent engine starting and smooth throttle response.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, this main jet carries the same part number — 5100001088 — used by authorized service dealers, ensuring you receive the correct component every time.
- Direct Carburetor Drop-In: — Engineered to seat and thread into the carburetor body the same way as the original, with no reworking of the fuel circuit needed.
- Broad BPU Series Coverage: — Verified fit across BPU 3050A, BPU 3050A US, BPU 3750Ats, BPU 3750Ats US, BPU 4045A, and BPU 4045A US reversible vibratory plate compactors, plus PT3A and PT3A(I) trash pumps.
- Restores Full Power Output: — A worn, clogged, or incorrect main jet starves the engine of fuel under load, causing bogging and loss of compaction or pump performance. Replacing it with a correctly sized OEM jet restores peak RPM and full working output.
The main jet is a precisely sized metering component located inside the carburetor's fuel circuit. It controls the volume of fuel delivered to the engine at mid-to-full throttle, and its orifice diameter is calibrated specifically for the engine displacement and carburetor model it serves. When the main jet becomes clogged with varnish deposits or debris, the engine runs lean — leading to rough running, overheating, power loss, or failure to sustain load. On compaction equipment like the BPU series, this directly undermines plate performance and compaction output; on trash pumps like the PT3A, it limits the engine's ability to maintain priming speed and pump capacity under demand.
