The Wacker Neuson 5200015288 Main Jet is a genuine OEM component designed for the BS50-4As, BS60-4As, and BS70-4As vibratory rammers. As a direct OEM replacement, this main jet is sourced and manufactured to the same specification as the original part installed at the factory, ensuring correct fuel metering for consistent engine performance across the full BS-series rammer lineup. The 5200015288 covers a wide range of BS-4As configurations including standard, high-altitude, and GRX variants, making it the go-to replacement jet for technicians servicing multiple units in the field.
Key Features
- Calibrated Fuel Orifice: — Precision-sized jet orifice delivers the correct air-fuel ratio for the BS-4As engine, maintaining proper combustion at rated operating speed.
- Genuine OEM Sourcing: — Manufactured to Wacker Neuson's original specification, so the fuel flow rate matches what the carburetor was designed around — no guesswork on sizing.
- Broad BS-4As Coverage: — Fits BS50-4As, BS60-4As, and BS70-4As rammers across standard, high-altitude, GRX, and plastic-shoe configurations, including US-market variants.
- Drop-In Carburetor Fit: — Threads directly into the existing carburetor body using the original seat, requiring no additional hardware or carburetor disassembly beyond jet access.
- Protects Engine Efficiency: — A worn or partially blocked main jet causes lean running, hard starting, and power loss under load; replacing it restores full rammer stroke and compaction output.
The main jet is a small but critical metering component inside the carburetor. It controls the volume of fuel drawn into the air stream during mid-range and wide-open throttle operation — essentially setting how rich or lean the engine runs under load. On a vibratory rammer like the BS50-4As, BS60-4As, or BS70-4As, a correctly sized and unobstructed main jet is essential for maintaining the consistent engine RPM needed to produce full compaction force with every stroke. When the main jet becomes clogged, corroded, or worn, the engine loses power, runs rough, or refuses to pull cleanly under load, reducing compaction effectiveness and increasing wear on other engine components.
