As a direct OEM replacement sourced through Multiquip's authorized parts network, 71974051350 ensures the precision tolerancing and flow calibration required by the 3TNV76 engine series. This assembly is confirmed to fit AR16-2 roller applications, making it the correct choice when restoring full engine performance on that machine.
Key Features
- OEM-Calibrated Fuel Delivery — Built to the exact injection pressure and timing specifications of the 3TNV76 engine, ensuring consistent fuel atomization and combustion efficiency across the AR16-2's operating range.
- Direct-Mount Replacement — Engineered to match the original pump's mounting pattern, port orientation, and drive coupling, allowing a straightforward swap with no fitment adaptation.
- Confirmed AR16-2 Compatibility — Verified fitment for the Multiquip AR16-2 ride-on asphalt roller; reference part number 71974051350 when ordering to ensure you receive the correct assembly for this machine.
- Restored Engine Output — A worn or failing injection pump causes hard starting, uneven idle, power loss, and excessive smoke; replacing it with this genuine assembly restores full rated power and smooth throttle response.
- Fuel System Integrity — Genuine OEM construction maintains the tight internal clearances and seal integrity critical to preventing unmetered fuel delivery, which can damage injectors and affect emissions compliance on diesel-powered equipment.
The fuel injection pump is the heart of a diesel engine's fuel system. It pressurizes fuel from the tank and delivers precisely metered, high-pressure charges to the injectors at the correct moment in each combustion cycle. On the AR16-2's 3TNV76 engine, a properly functioning pump is essential for consistent power output, smooth roller operation, and efficient fuel consumption. When the pump wears internally or fails, symptoms include difficult cold starts, rough running, black or white exhaust smoke, and a noticeable drop in drive and vibration performance — all of which bring compaction work to a halt until the pump is replaced.
