For industrial maintenance teams sourcing dependable Caterpillar fuel system components, the CAT 155-1819 precision diesel fuel injector delivers consistent, OE-matching performance for heavy-duty engine platforms. It is engineered to deliver precisely metered fuel into the combustion chamber at high pressure, atomize diesel for optimized combustion efficiency, and maintain accurate injection timing and spray patterns to support engine performance. The assembly withstands the high temperatures and extreme vibration common in demanding Caterpillar heavy-duty operating environments.
Each 155-1819 injector is machined to strict precision tolerances, with verified cross-reference numbers 20R-4148, 4CR01974, 198-4752 and 0R-9350 for easy cross-referencing across supplier catalogs. It fits CAT 3412, 3412E, 3126B and 3512B diesel engines, with heavy-duty core components including high-pressure nozzles, plunger and barrel assemblies, control valves and precision seals. Buyers should confirm the exact engine serial number before ordering, as injector calibration varies by unit.
Installation must be completed by a certified diesel technician, with torque and calibration procedures following official Caterpillar service manuals. The injector meets relevant ISO quality standards, with OEM and premium aftermarket options, and carries a typical 6–12 month warranty depending on the supplier. It suits diverse industrial use cases, including construction equipment, power generation, mining, oil fields, and marine power systems, with regular fuel system maintenance recommended to extend service life.
