The Wacker Neuson Metering Diaphragm Assembly is a genuine OEM component designed for the P35A power unit, BV35A-P backpack vibrator, PV35A pole vibrator, and PG1 dewatering pump series. Sourced directly from Wacker Neuson, this is the same assembly installed at the factory — no guesswork on fit or compatibility. Part number covers a broad range of P35A and associated machine configurations, including EU variants, making it a go-to service part for fleets running multiple units. When your carburetor's metering function starts to fail, this assembly gets your equipment back to proper fuel regulation quickly.
Key Features
- OEM-Grade Diaphragm Material — Manufactured to Wacker Neuson's exact material and thickness specifications, ensuring the diaphragm flexes and seals correctly under real operating pressures rather than approximating them.
- Drop-In Carburetor Fit — Designed to seat directly into the metering chamber of the compatible carburetor with no trimming or shimming — installs the same way the original came out.
- Wide Model Coverage — A single part number covers P35A power units, BV35A-P backpack vibrators, PV35A pole vibrators, and PG1 dewatering pumps, including standard and EU variants.
- Restores Consistent Fuel Metering — A worn or ruptured metering diaphragm causes erratic idling, hard starting, and power loss; replacing it with 5000217165 restores stable, predictable engine response.
- Fuel System Integrity — A correctly functioning metering diaphragm maintains controlled fuel delivery and prevents unmetered fuel from entering the engine — critical for safe, consistent operation on site.
The metering diaphragm assembly is a core component inside the carburetor's metering circuit. It acts as a flexible pressure-sensing membrane that regulates how much fuel is drawn into the engine based on demand — essentially the carburetor's way of matching fuel delivery to throttle position and load. When the diaphragm becomes stiff, cracked, or perforated from age or fuel exposure, the metering circuit loses its ability to respond accurately, resulting in symptoms like rough idling, bogging under load, or an engine that refuses to start. Replacing the assembly with a genuine Wacker Neuson part restores the precise flex and seal characteristics the carburetor was designed around.
