Perkins original Perkins 282-0490 Diesel Fuel Injector Replacement for C6.5 C6.4 C4.2 320D Excavator Engine Spare Part new injector original new injector

The Perkins 282-0490 fuel injector is a direct OEM replacement designed for Perkins C6 and C6.6 inline 6-cylinder diesel engines, with aftermarket cross-reference compatibility to the 1106D-E66TA platform. Manufactured to original equipment specifications, this injector carries the authorized Perkins OE numbers 282-0490, 10R-7668, 276-8290, 289-7501, 293-9590, 321-0990, 2645A709, 1106D, and 1106D-E66TA, ensuring verified fitment across genuine and remanufactured engine programs. Each unit is precision-machined with hardened internal components and a corrosion-resistant nozzle assembly, delivering consistent high-pressure fuel atomization under heavy-duty operating conditions in construction, mining, agriculture, power generation, marine, and stationary industrial equipment such as Perkins 938H, 963D, 120M, 12M, C6.6 generator sets, and C6 series excavators.

Functioning as a high-pressure precision metering device installed in the cylinder head, the injector receives pressurized diesel from the CP3 high-pressure pump and opens precisely according to ECU or mechanical timing commands. It atomizes fuel through calibrated nozzles and injects the spray into the combustion chamber at optimal timing, supporting efficient combustion, balanced cylinder output, and stable idle performance. Every injector undergoes full pressure testing, spray pattern inspection, and leakage verification before shipment to meet OEM equivalent quality standards for industrial durability and long service life.

For installation, clean the fuel system thoroughly, inspect the injector bore, and follow Perkins torque specifications during assembly. Check all fuel lines for integrity, perform leak testing upon completion, calibrate the ECU where applicable, and conduct an engine test run to confirm performance. Routine maintenance includes filter checks every 500 hours, fuel system inspection every 1000 hours, injector testing every 2000 hours, and a comprehensive fuel system evaluation every 3000 hours to sustain reliable engine operation.
