The Multiquip 11980203131 is a genuine OEM Diaphragm 3TNV76 AR16-2 designed for the AR16-2 asphalt ride-on roller. As a direct Multiquip OEM component, it is manufactured to the same specifications as the original part, ensuring a correct installation and proper system function. DHS Equipment stocks this part to keep your AR16-2 roller operating at full capacity with the reliability you expect from genuine Multiquip components.
Key Features
- Genuine OEM Diaphragm Construction — Produced to OEM material and flex-fatigue specifications, ensuring the diaphragm maintains consistent membrane integrity under repeated pressure cycles.
- Direct-Fit for AR16-2 — Engineered specifically for the AR16-2 asphalt ride-on roller, matching the original mounting profile and port dimensions for a straightforward installation.
- 3TNV76 Engine Compatibility — Matched to the 3TNV76 engine configuration fitted to the AR16-2, so there is no guesswork when sourcing the correct diaphragm for your machine.
- Sustained Fuel or Fluid Delivery — A correctly functioning diaphragm maintains proper pressure and flow in the fuel or fluid circuit; a worn or cracked diaphragm causes erratic engine performance, hard starting, or fluid leaks.
- Fuel System Integrity — Replacing a degraded diaphragm promptly prevents fuel seepage and the associated fire risk, making this a safety-relevant service item on any gasoline or diesel-powered machine.
A diaphragm is a flexible membrane used inside fuel pumps and carburetors to create the pulsating pressure that draws fuel from the tank and delivers it to the engine at the correct rate. On the AR16-2 roller's 3TNV76 engine, this component flexes continuously during operation, and over time the material can stiffen, crack, or develop pinholes. When that happens, fuel delivery becomes inconsistent, leading to rough running, stalling, or an inability to start. Replacing the diaphragm at the first sign of fuel delivery issues restores normal engine operation and prevents more extensive damage to downstream fuel system components.
