Caterpillar original Replacement Fuel Injector Assembly 6L4360 10R-1252 OEM 111-3718 0R-8338 Diesel Engine Part for Construction Machinery Excavator original new injector

The Caterpillar (CAT) 6L4360 high-pressure diesel fuel injector is an industrial-grade precision component designed for CAT 3512A series diesel engines, with verified compatibility with CAT 3512B and CAT 3516 engine platforms. As an OE 340-4360 certified part manufactured to meet or exceed strict OEM specifications, it serves as a direct-fit replacement solution for fleet operators and equipment maintenance teams, serving power generation, construction, mining, marine and manufacturing industries.

Constructed from high-strength alloy steel, this injector supports 1500–1800 bar operating pressure and uses a multi-hole precision atomization spray pattern to optimize fuel combustion, boost overall engine efficiency and reduce harmful exhaust emissions. Its high-pressure common rail design maintains stable, accurate fuel delivery under sustained heavy loads, while thermal fatigue and corrosion resistance extend service life for continuous industrial use, with a standard CAT injector plug for hassle-free direct installation.

Every 6L4360 injector is fully calibrated to match original Caterpillar performance requirements and comes with a 12-month industrial warranty for reliable quality assurance. It fits a wide range of equipment including diesel generator sets, 3500-series excavators, marine propulsion engines and heavy manufacturing machinery, helping operators reduce unplanned downtime and lower long-term operational costs. Routine wear inspection and use of high-pressure rated fuel filters can further maximize its service lifespan.
