The Multiquip 11980203141 Spring Diaphragm 3TNV76 AR16-2 is a genuine OEM component designed for the AR16-2 asphalt ride-on roller. Sourced directly from Multiquip, this part meets the exact specifications required to restore proper diaphragm function in the 3TNV76 engine system fitted to the AR16-2. Fitment is confirmed for AR16-2 series equipment, so you can order with confidence knowing this is the correct part for your machine.
Key Features
- Genuine OEM Diaphragm Material — Manufactured to the same material and flex specifications as the original, ensuring consistent sealing performance under the operating pressures of the 3TNV76 engine.
- Direct Drop-In Replacement — Engineered to match the original mounting dimensions and spring tension of the AR16-2 diaphragm assembly for a straightforward installation.
- Confirmed AR16-2 Fitment — Verified for the Multiquip AR16-2 asphalt ride-on roller; eliminates guesswork when sourcing a replacement diaphragm spring for this machine.
- Restores Proper Fuel or Pressure Regulation — A worn or fatigued diaphragm spring affects pressure balance and response; replacing it with 11980203141 brings the system back to correct operating behavior.
- Supports Extended Service Life — Using the correct OEM spring diaphragm prevents premature wear on adjacent components caused by mismatched spring rate or improper sealing.
A diaphragm spring works in conjunction with a flexible diaphragm membrane to regulate pressure or fuel flow within the engine's fuel delivery or control system. The spring provides the calibrated resistance needed to keep the diaphragm seated and responsive under varying engine demands. When the spring weakens, cracks, or loses tension, the diaphragm can no longer maintain proper pressure balance — leading to inconsistent fuel delivery, rough running, or engine hesitation that affects the compaction performance of your roller.
