Perkins original Perkins 356-1373 Fuel Injector Nozzle Injection Valve Replacement for C15 C18 Caterpillar Engine new injector original new injector

Engineered for industrial reliability, this Perkins fuel injector carries the authorized OE numbers 356-1373 / 3561373, CA3561373, 20R-5353 / 20R5353 and CA20R5353, and cross-references 359-4050, 10R-0955, 10R-0956, 10R-0957, 10R-0958, 10R-7228, 10R-1273, 356-1367, 211-3025 and 20R-0955 for direct compatibility with Perkins C15, C18, C32, C16, 3406E and 3456 diesel engines. The part is purpose-built to deliver the correct fuel volume at the right moment into the combustion chamber, supporting stable idle, fast cold start, reduced black smoke and improved fuel economy across heavy duty trucks, generator sets, wheel loaders, track-type tractors, articulated trucks, load haul dump machines, excavators, front shovels, wheel dozers, soil compactors, landfill compactors and petroleum engines including AD30, R2900G, 988G, 980G, D8R, D8N, 385B and 5090B.

Available in both new and remanufactured options, the injector adopts heavy-duty internal components and precision-machined nozzles to handle modern low-sulfur, low-lubricity diesel fuels while maintaining correct cylinder pressure, balanced cylinder temperature and rated power output. Proper atomization lowers unburned hydrocarbon emissions and protects the piston, liner and valve train from thermal overload. Each unit is offered with flexible packaging and global supply chain compatibility, helping fleet operators and rebuild workshops reduce downtime and standardize inventory with a single OE-number family.

Routine service includes the use of clean diesel, scheduled fuel filter replacement, water separator draining, periodic injector testing during engine overhaul, seal replacement after removal, and inspection of ECM fault codes and cylinder balance data. Common diagnostic symptoms pointing to injector service include hard starting, rough idle, black or white smoke, engine knock, low power, elevated fuel consumption, fuel in oil, misfire detected through cylinder cutout, excessive exhaust temperature, external fuel leakage and active injector-related ECM codes. For correct fitment, always confirm the engine serial number and original injector part number prior to purchase.
