Caterpillar original Caterpillar 250-1314 diesel fuel injector 2501314 replacement for OEM new injector original new injector

The Caterpillar 250-1314 fuel injector is engineered as a direct OEM replacement for CAT 3512B diesel engines, with verified cross-compatibility across 3508B, 3516B, PM3512, and PM3516 platforms. Manufactured under OEM-precision machining standards, each unit is built with tight dimensional tolerances to ensure correct fitment within the engine cylinder head and consistent injector body geometry. High-strength alloy steel construction provides resistance to thermal stress, vibration, and corrosion, supporting stable long-term operation in industrial, marine, power generation, mining, and oilfield service environments. Authorized cross reference numbers include 10R-1290, 20R-1275, 392-0214, 386-1766, 229-0193, 150-4456, 126-7995, 114-6469, 0R-8892, and 0R-8690.

Featuring high-pressure fuel handling capability and an advanced atomizer design, this injector delivers uniform fuel spray patterns that improve air-fuel mixing, support cleaner combustion, and contribute to reduced exhaust emissions. The thermal-stress-optimized internal components maintain stable injection performance under continuous load conditions typical of prime power, standby genset, and heavy-duty marine propulsion applications. Every unit is individually sealed in protective packaging, certified to ISO and CAT quality assurance standards, and backed by OEM warranty availability for professional aftermarket channels.

Prior to installation, technicians should clean the cylinder bore and fuel supply passages, fit new O-rings, inspect the injector seat and tip condition, apply the manufacturer-specified torque value, and conduct both a leak test and a spray pattern verification. Proper calibration of injection timing ensures that the 250-1314 injector restores original engine performance, fuel efficiency, and emission compliance for CAT 3512B, 3508B, and 3516B engine platforms operating across global industrial and marine markets.
