The CAT 295-9130 fuel injector is engineered specifically for Caterpillar C6 and C6.4 diesel engines, delivering precision fuel metering within high-pressure common rail systems. Electronic solenoid activation is fully compatible with the original Caterpillar engine ECM / ECU mapping, ensuring calibrated injection timing and optimized combustion. The multi-hole nozzle design produces a refined spray pattern that improves atomization, enhances thermal efficiency, and reduces exhaust smoke under varying load conditions. A full series of authorized cross reference numbers — 10R-7675, 326-4700, 317-2300, 32F61-00060, 32F61-00062, and CAT2959130 — supports direct replacement across construction, marine, generator, and industrial equipment.

Manufactured to OEM-grade standards, the injector is built from high-strength alloy steel with heat treatment for wear resistance and a corrosion-protected surface finish for extended service life. Every unit passes dynamic flow testing, leak testing, electrical activation testing, spray pattern verification, and factory testing before shipment. The component is suited for excavators, loaders, backhoes, generators, compressors, mining machinery, agricultural engines, marine engines, and oil & gas power units. Major deployment regions include North America, Europe, the Middle East, Africa, Southeast Asia, Australia, and South America, making it a reliable supply option for international distributors and fleet operators.

Routine maintenance supports long-term reliability: inspect the fuel filter every 250 hours and replace it every 500 hours, conduct injector flow testing every 1000 hours, and verify injector calibration every 2000 hours. Installation requires a contamination-free environment, a clean carbon-free injector bore, a proper electrical connection, OEM Caterpillar torque values, and replacement of all seals and washers. Common fault symptoms such as hard starting, black smoke emission, white smoke, rough idle, and increased fuel consumption can often be traced to nozzle wear, solenoid failure, or internal leakage, and are typically resolved through flow testing, ECM diagnostics, or injector replacement to restore stable engine performance.
