original 20R-1276 Fuel Injector 20R1276 3920214 Common Rail Diesel Engine Parts for 3508 3512 3516 original new injector

Engineered specifically for the 3512B series, this 2OR-1276 fuel injector delivers precise direct fuel injection optimized for the combustion chamber geometry of the 3512B, 3516, and 3520 diesel platforms. The spring-loaded plunger and high-precision nozzle produce a consistent spray pattern that supports clean combustion, reduced smoke output, and stable engine performance under demanding industrial and marine duty cycles. With high-pressure capability up to 2200 bar and a flow rate of 50–60 L/h at 2000 RPM, the injector maintains accurate fuel metering across the full operating range.

Manufactured from high-grade alloy steel with heat-treated internal components, anti-wear coating, and corrosion-resistant surfaces, the 2OR-1276 is built to withstand continuous operation in harsh environments. OEM-standard mounting dimensions allow direct replacement without modification, with a recommended installation torque of ~50–60 Nm. The injector operates reliably across a wide temperature range of -40°C to 120°C, making it suitable for power generation, mining, marine, construction, and oil and gas applications. Authorized OE and cross-reference numbers include 2OR-1276, 0R-1276, 9W-7756, 7N-1234, 2OR-1276A, 1R-1223, and 0R-1280.

Routine maintenance should be performed every 500–1000 hours, including inspection of O-rings and sealing washers, ultrasonic cleaning of nozzle tips using approved solvents, and verification of fuel flow rate and spray pattern through ECU diagnostics. The 2OR-1276 is backed by a 12-month / 1000-hour warranty and shipped worldwide with tracked, insured logistics and anti-static protective packaging.
