Caterpillar original 289-0753 Diesel Engine Fuel Injector for C15 C18 C11 C10 3406E Excavator Replacement for OEM 10R-3263 20R-5036 234-1400 new original new injector

The Caterpillar C15 fuel injector 289-0753 is an OEM-quality electronic unit injector engineered for the CAT C15 ACERT engine platform, covering 15.2-liter inline six-cylinder configurations used across heavy-duty industrial and mobile applications. Built to original equipment manufacturing standards, this injector assembly delivers high-pressure fuel delivery with precise atomization, optimized spray pattern geometry, and stable idle operation, supporting improved combustion efficiency, increased engine power output, and reduced particulate emissions under demanding load conditions.

Manufactured with corrosion-resistant materials and industrial-grade durability, the 289-0753 injector withstands harsh operating environments encountered in mining trucks, construction equipment, wheel loaders, excavators, highway trucks, and generator sets. Each unit is calibrated to meet original performance specifications for the CAT C15 ACERT, C15 ERT, and related C15 engine variants, ensuring consistent fuel metering and reliable cold-start response across continuous-duty and emergency backup power applications. The assembly is interchangeable with cross reference numbers 10R-0955 and 328-2585, providing a direct-fit replacement solution for fleet operators and equipment maintenance providers.

Proper installation requires relieving fuel system pressure, replacing injector bore sealing components, applying manufacturer-specified torque values, and recalibrating the ECM where required, followed by a fuel leak test and performance verification. Routine maintenance using clean diesel fuel and regularly replaced fuel filters extends injector service life and preserves combustion efficiency. Backed by a 12-month warranty, the 289-0753 fuel injector offers a dependable OEM-equivalent replacement for CAT C15 powered machinery operating in mining, construction, transportation, and power generation sectors.
