The Wacker Neuson Diaphragm Assembly is a genuine OEM component designed for the CRT36-25 915mm/36in Ride-on Trowel, including models CRT36-25. Sourced directly from Wacker Neuson, this assembly meets the same specifications as the part originally installed at the factory — so you can replace it with full confidence in fit and function. It covers both the standard CRT36-25 and the Wheel Kit-equipped variant, making it the right call for any CRT36-25 in your fleet. Keep part number on hand and you won't be caught waiting when a diaphragm change is due.
Key Features
- OEM Flex Material Integrity — Manufactured to Wacker Neuson's diaphragm material spec, delivering the correct flex response and chemical resistance for sustained fuel or fluid system performance.
- Drop-In Assembly Replacement — Supplied as a complete assembly, so installation matches the original mounting configuration without sourcing individual components separately.
- CRT36-25 Series Coverage — Fits both the standard 915mm/36in CRT36-25 Ride-on Trowel and the CRT36-25 Ride-on Trowel with Wheel Kit.
- Consistent Pressure Regulation — A correctly functioning diaphragm maintains stable fuel or fluid delivery; a cracked or fatigued diaphragm leads to erratic engine response, hard starting, or stalling under load.
- Fuel System Safety — Diaphragm integrity is critical to preventing uncontrolled fuel passage; using a genuine OEM assembly ensures the correct sealing performance in this safety-relevant circuit.
A diaphragm assembly is a flexible membrane used in carburetors and fuel pumps to regulate and move fuel through the system by responding to pressure differentials. It flexes with each engine cycle to draw fuel from the tank and deliver a consistent, metered supply to the carburetor. When the diaphragm cracks, hardens, or develops pinholes, fuel delivery becomes inconsistent — typically causing rough running, poor throttle response, or a no-start condition — making timely replacement essential to keeping the trowel operating at full capacity.
