Caterpillar original Replacement Common Rail Fuel Injector 0R-3052 for Caterpillar 3500A 3508 Engines, Cross Reference 7E6408 0R-1759, Replacement for OEM 0R8338, Fits Excavator original new injector

Engine downtime in power generation, marine, and mining operations demands replacement components that fit right the first time. The Caterpillar 0R-3052 fuel injector is engineered specifically for the CAT 3512A diesel engine platform, covering generator, marine propulsion, industrial, mining, and power generation configurations. Cross-referenced against 0R3052, 209-3082, and 239-7471, this injector gives procurement teams a verified interchange path for CAT 3512A engines operating in generator sets, marine vessels, oilfield machinery, and heavy-duty construction equipment.

Built to OEM specifications, the injector delivers precise fuel metering and superior atomization under high-pressure operating conditions. Advanced nozzle technology and precision-machined internal components produce a consistent spray pattern, supporting efficient combustion, optimized fuel economy, and reduced smoke and particulate emissions. Heat-treated alloy steel construction provides corrosion resistance and high-temperature stability, extending service life in harsh marine and industrial environments. As a direct OEM fitment, the 0R-3052 installs without modification, minimizing labor time for fleet operators and engine rebuilders.

For reliable operation, CAT-approved maintenance procedures are recommended: clean injector seating surfaces, replace sealing washers, inspect fuel supply lines, verify injection timing, and perform post-installation leak testing. Service life is maximized by using high-quality diesel fuel, avoiding contaminated fuel, monitoring exhaust smoke, and performing periodic fuel pressure and return-flow testing. For Caterpillar dealers, engine rebuilders, maintenance contractors, and power generation facilities, the 0R-3052 is a dependable OEM-specification solution—contact us for pricing and availability.
