Caterpillar original Caterpillar 10R-8795 diesel fuel injector replacement for CAT C9 engine new injector original new injector

The CAT 10R-8795 fuel injector is an OEM-specification Electronic Unit Injection component engineered for the Caterpillar 3512B engine platform, serving industrial, marine, power generation, oilfield, and mining applications. Built with a precision machined nozzle, hardened internal components, and high pressure design, it delivers OEM flow calibration within the EUI system. Construction from corrosion resistant, high strength alloy steel ensures reliable performance under continuous operation duty cycles in demanding environments such as generator sets, marine propulsion engines, offshore platforms, mining trucks, and drilling equipment.

This injector assembly provides precise fuel metering, improved fuel atomization, and higher combustion efficiency, supporting increased engine power, reduced fuel consumption, and lower emissions. Installation is straightforward via direct replacement at the cylinder head position, with no modification required. Routine maintenance including fuel filter inspection, fuel quality check, injector performance test, ECM diagnostic scan, fuel system cleaning, and injector calibration verification helps sustain long-term reliability and consistent engine performance across heavy duty applications.

The authorized OE reference for this part is 10R-8795, with cross reference numbers 10R8795, 10R8796, 170-5187, and 1705187, providing broad interchangeability for CAT 3512B spare parts requirements. Typical fault indicators such as hard starting, excessive smoke, power loss, rough idle, increased fuel consumption, misfire, and engine knock point toward injector wear, poor atomization, fuel delivery restriction, internal leakage, or injector sticking, making timely replacement essential to protect engine integrity and maintain operational uptime.
