Caterpillar original 7C-0345 Common Rail Diesel Fuel Injector for 3500A Engine Replacement for OEM 4W-3563 7C-2239 7C-4173 10R-3053 original new injector

Engineered as a direct OEM replacement, the CAT Fuel Injector 7C-0345 delivers reliable fuel delivery for Caterpillar 3512A diesel engines operating in heavy duty industrial environments. Each injector is manufactured to meet Caterpillar quality benchmarks, incorporating precision CNC machined nozzles that ensure consistent spray pattern and proper fuel atomization across the full operating range. The hardened alloy internal components are built to withstand extreme cylinder pressures and elevated temperatures commonly found in continuous duty applications.

This injector is fully compatible with the CAT 3512A and supports secondary engine platforms including CAT 3512, CAT 3512B, CAT 3508, and CAT 3516 subject to configuration verification. It serves a wide range of equipment categories, from marine main propulsion and auxiliary power units to prime power and emergency generator sets, mining haul trucks, excavators and drills, as well as oil and gas field installations and heavy construction machinery. Authorized cross references include 0R-2924, 0R-2411, 7C4175, 6I4356, 7E-6048, 7E-8836, 4W-3563, and 7C-2239, simplifying fleet sourcing and interchange.

Every unit passes a multi-point inspection covering leakage, flow rate, and spray pattern validation, providing confidence in installations where downtime carries high cost. Corrosion resistant construction supports dependable service in marine and harsh outdoor environments, while high pressure capability maintains performance under sustained heavy load. Routine fuel filter replacement, periodic injector performance testing, and preventive fuel system cleaning are recommended to maximize service life and preserve combustion efficiency.
