Precision-engineered as a core fuel injection component for Caterpillar 3412 Series V12 diesel engines, the 10R1262 fuel injector is purpose-built to deliver consistent, OEM-spec performance for compatible CAT engine platforms. It fits standard 3412, 3412B, 3412C, marine, generator and industrial 3412 engine variants, with 3412E compatibility requiring verification via engine serial number to ensure proper fitment. Installed at the cylinder head fuel injection port, it adheres to strict OEM manufacturing tolerances for seamless integration with existing engine systems.
The mechanical unit injector performs four core combustion functions: precise fuel metering, high-pressure fuel pressurization, precision fuel atomization, and uniform in-cylinder fuel distribution. These functions optimize power output, fuel economy, engine response and emission control while supporting long engine service life. Built with hardened wear-resistant and corrosion-resistant materials, it withstands extreme high-load continuous-duty conditions across power generation, marine propulsion, mining, oil and gas, construction and industrial applications.
Available in new or remanufactured options to suit different operational budgets, the injector comes in industrial export packaging and carries a 12-month warranty. It supports global cross-reference checks against part numbers including 10R1262RX, 0R3421, 4P9830 and 7W7032, with official installation and maintenance guidance available to reduce unplanned downtime and lower long-term fleet operating costs.
