The Wacker Neuson Jet Main is a genuine OEM component designed for CRT36-25 and CRT36-26A-WK 915mm/36-inch ride-on trowels. As a direct OEM part sourced from Wacker Neuson, it meets the exact specifications of the original component installed at the factory — no guesswork on calibration or fitment. This part is confirmed to fit the CRT36-25 series, including configurations with and without the wheel kit, as well as the CRT36-26A-WK variant. When your trowel's fuel delivery is off, replacing the jet main with the correct OEM part restores proper carburetor function and keeps the engine running at its intended performance level.
Key Features
- OEM-Spec Fuel Metering: — Manufactured to Wacker Neuson's original flow-rate specifications, ensuring accurate fuel delivery rather than an approximated aftermarket equivalent.
- Drop-In Carburetor Fit: — Engineered to seat directly into the carburetor body of compatible CRT36 trowels without adaptation or re-jetting.
- Broad CRT36 Series Coverage: — Fits CRT36-25 standard, CRT36-25 with wheel kit, CRT36-25 (5000620803), and CRT36-26A-WK (5000620804) machines.
- Restored Engine Response: — A correctly sized jet main maintains the air-fuel ratio the engine needs for smooth throttle response and consistent power output across finishing passes.
- Fuel System Safety: — An OEM-matched jet prevents rich or lean conditions that can cause overheating, hard starts, or uncontrolled engine behavior on ride-on equipment.
The jet main is a precision-drilled orifice installed inside the carburetor that meters the flow of fuel into the engine's air stream. Its bore diameter is calibrated to deliver the correct fuel quantity at operating RPM — too large and the engine runs rich and sluggish; too small and it runs lean, risking overheating and power loss. On ride-on trowels like the CRT36-25 series, where consistent engine speed directly affects finishing quality, a worn, clogged, or incorrect jet main can cause uneven blade speed, difficult starting, and excessive fuel consumption.
