Caterpillar original 6L4360 0R-8338 111-3718 10R-1252 6I-4357 fuel injector assembly for 3512A engine excavator replacement original new injector

The Caterpillar 3512A Fuel Injector, OE 340-4360, is a high-performance diesel fuel injection component engineered to deliver reliable combustion efficiency in demanding industrial environments. Designed to meet Caterpillar original specifications, this injector supports a high-pressure operating range of 1500–1800 bar, ensuring optimized fuel atomization and consistent spray patterns across the full engine operating range. Its multi-hole precision atomization design promotes complete fuel burn, contributing to improved fuel economy and reduced exhaust emissions in heavy-duty applications.

Constructed from high-strength alloy steel, the 340-4360 injector is built to withstand thermal fatigue, corrosion, and the mechanical stresses of continuous industrial operation. It serves as a direct replacement for the 6L-4360, 3404360, and 6L4360A cross-reference numbers, making it compatible with CAT 3512A, CAT 3512B, and CAT 3516 series diesel engines used in diesel generator sets, excavators, marine engines, and other heavy machinery. The injector is well suited for power plants, construction sites, marine operations, manufacturing facilities, and mining equipment.

Routine maintenance includes periodic inspection for nozzle wear and clogging, use of fuel filters rated for high-pressure systems, and approved ultrasonic cleaning. Replacement is recommended at the first sign of performance degradation to protect the engine. Installation should be performed with the engine off and cooled, using a calibrated torque wrench to OEM specifications, followed by leak checks on all fuel and electrical connections.
