The Wacker Neuson Main Jet is a genuine OEM component designed for BPU 5545A, BPU 5545A US, BPU5260Ah, and BPU6275Ah reversible plate compactors. Sourced directly from Wacker Neuson, this part meets the exact specifications required for proper carburetor fuel delivery in these machines. Correct fitment matters with fuel system components, and the installs directly into the original carburetor position with no adaptation needed. If your compactor is running lean, flooding, or surging under load, a worn or clogged main jet is one of the first components to inspect and replace.
Key Features
- OEM Fuel Metering Accuracy — Manufactured to the precise orifice size specified by Wacker Neuson, ensuring the correct air-to-fuel ratio for consistent engine performance.
- Direct Carburetor Drop-In — Matches the original thread pitch and jet diameter of the factory carburetor, so installation is straightforward with standard carb tools.
- Confirmed Fitment for BPU Series Compactors — Verified for BPU 5545A, BPU 5545A US, BPU5260Ah, and BPU6275Ah models, covering both standard and US-spec variants.
- Restores Full-Throttle Power — A correctly sized main jet allows the engine to reach its rated output under compaction load; a worn or blocked jet causes power loss, rough running, and incomplete compaction passes.
- Fuel System Safety — A properly seated OEM main jet maintains the designed fuel flow path, preventing lean-run conditions that can cause overheating and engine damage.
The main jet is a small but critical component inside the carburetor that meters the volume of fuel delivered to the engine at mid-to-full throttle. It works by allowing a precisely sized opening to control fuel flow as the engine draws in air, keeping the mixture within the range the engine needs to run cleanly and efficiently. When the main jet becomes clogged with varnish or debris, or wears to an oversize condition, the engine will run erratically, lose pulling power, or stall under load — symptoms that are easy to mistake for broader engine problems but are often resolved simply by cleaning or replacing this single component.
