Caterpillar original Caterpillar 282-0490 fuel injector replacement for OEM diesel engine spare part new injector original new injector

The CAT 282-0490 fuel injector is engineered for Caterpillar C6 and C6.6 inline 6 diesel engines, also cross-referenced to the Perkins 1106D-E66TA platform. Produced as an OEM-equivalent replacement part, this injector integrates precision-machined spray nozzles and hardened internal components to deliver consistent high-pressure fuel atomization under demanding industrial load conditions. It serves as a direct-fit solution across CAT 938H, 963D, 120M, and 12M equipment, along with C6.6 generator sets and C6 series excavators used in construction, mining, agriculture, power generation, marine, and stationary industrial applications.

Installed within the cylinder head and supplied by a CP3 high-pressure pump, the injector receives pressurized diesel and disperses it through calibrated nozzles to support efficient combustion. Each unit is fully tested to confirm flow rate, spray pattern, and leak integrity prior to shipment, ensuring reliable performance comparable to original factory specifications. Corrosion-resistant materials and reinforced sealing surfaces contribute to long service life in harsh operating environments, reducing unplanned downtime and supporting stable engine output across heavy-duty equipment fleets.

For proper installation, technicians should clean the fuel system, inspect the injector bore, follow CAT torque specifications, verify fuel line connections, and perform leak testing along with ECU calibration and an engine test run where applicable. Routine maintenance is recommended at 500-hour filter checks, 1000-hour fuel system inspections, 2000-hour injector testing, and 3000-hour comprehensive system evaluation.
