Perkins original Perkins 20R-3483 Diesel Fuel Injector for 3512B 3516B 3512C 3516C Engine Excavator new injector original new injector

The Perkins 3512B fuel injector 20R-3483 is an original equipment quality diesel fuel injection assembly engineered for the Perkins 3500 series V12 turbocharged engines. Manufactured using CNC machining processes with micron-level tolerances, each injector is factory calibrated to match Perkins fuel system specifications, ensuring precise fuel metering and consistent delivery across all engine loads and operating conditions. The component delivers uniform fuel atomization and an optimized spray pattern that supports cleaner combustion and measurable fuel efficiency improvements.

Designed specifically for continuous industrial operation, the 20R-3483 injector assembly is constructed from high-grade materials that provide excellent corrosion resistance against fuel contamination and harsh operating environments. It is built to withstand continuous operation under extreme fuel pressures, maintaining stable injection performance throughout extended service intervals. Comprehensive quality control procedures—including flow rate testing, leakage testing, spray pattern analysis, response time verification, pressure calibration, and endurance testing—guarantee that every unit meets OEM performance benchmarks before shipment.

This Perkins 3512B injector serves as a direct replacement for the original assembly and is widely applied across power generation systems, marine propulsion and auxiliary engines, mining haul trucks and drilling equipment, oil and gas compressor stations, and heavy-duty construction machinery. With a broad range of cross reference numbers including 10R-4931, 10R-4932, 2490713, 10R2827, 0R3539, 20R3247, 3754106, and 3861752, the injector offers reliable interchangeability for fleet maintenance, engine overhaul programs, and global aftermarket supply operations.
