Engineered specifically for the demanding operating conditions of 3500 Series V12 turbocharged diesel engines, this fuel injector carries primary OE reference 20R-3483 and offers direct cross-compatibility with 10R-4931, 10R-4932, 2490713, 10R2827, 0R3539, 20R3247, 3754106, 3861752 and remanufactured code 20R3483RX. It serves as a certified replacement component for 3512B power units and is equally suitable for 3508B, 3508C, 3512C, 3516B and 3516C platforms deployed in generator sets, marine propulsion systems, mining fleets and oilfield installations.

Manufactured with CNC-machined internal geometries and micron-level tolerances, the injector delivers OEM-calibrated fueling accuracy, superior atomization and an optimized spray pattern for cleaner, more efficient combustion. High-pressure capability, corrosion-resistant materials and heavy-duty construction ensure stable injection performance across all engine loads, extended service life under continuous industrial duty cycles, and measurable improvements in fuel efficiency and emissions. Direct OEM fitment allows straightforward drop-in replacement without modification to the fuel system.

Recommended maintenance includes daily inspection for fuel leaks, smoke levels, vibration and abnormal odors, plus weekly checks of fuel pressure, filters, electrical connectors and injector harnesses. For installation, clean the fuel system, inspect injector bores, fit new seals, follow torque specifications and complete a leak test with engine diagnostics verification. Ideal for OEM buyers, engine rebuilders and industrial MRO distributors worldwide.
