The Wacker Neuson Main Jet High Altitude is a genuine OEM component designed for the RD11V hydrostatic double drum vibratory tandem roller. As a factory-sourced part, it meets the exact specifications set during original production, ensuring the carburetor's fuel metering behavior matches what the engine was tuned to deliver. This jet is the correct high-altitude variant for RD11V machines operating in elevated environments where standard jetting would result in an over-rich fuel mixture.
Key Features
- OEM-Calibrated Fuel Orifice: — Sized to the precise bore specification required for correct air-fuel ratio at high altitude — not a universal approximation.
- Direct Carburetor Drop-In: — Threads directly into the carburetor main jet port of the RD11V with no modification to the fuel circuit or carburetor body.
- RD11V Tandem Roller Fitment: — Confirmed for the RD11V hydrostatic double drum vibratory roller series.
- Altitude Performance: — Restores proper combustion efficiency at elevation, preventing rough running, black smoke, or power loss caused by an overly rich fuel mixture.
- Fuel System Integrity: — Using the correct OEM jet maintains proper fuel delivery calibration, protecting the engine from the long-term wear associated with running a mismatched mixture at altitude.
A main jet controls the volume of fuel delivered through the carburetor at wide-open or high-load throttle positions. The high-altitude variant has a smaller orifice than the standard jet, compensating for the reduced oxygen density at elevation so the engine receives a correctly proportioned air-fuel mixture. When the wrong jet is fitted — or when a worn jet with an enlarged orifice is left in service — the engine runs rich, loses power, and produces excessive exhaust emissions; over time this can foul the spark plug and degrade engine performance on the RD11V.
