Caterpillar original For CAT 3406E C15 C16 C18 Engine, Fuel Injector 10R-8500 with 211-3023, Cross Reference 10R-8501, Replacement for OEM 10R-0957 original new injector

The Caterpillar 10R-8500 Fuel Injector Assembly is a precision-engineered diesel injection component designed for CAT C15 and C15 ACERT engine platforms. As a critical part of the engine’s high-pressure electronic unit injection system, it meters and delivers precisely measured fuel quantities into the combustion chamber to support controlled, efficient combustion. It is built to deliver consistent performance even in the most demanding heavy-duty diesel operating environments.

Manufactured to strict OEM specifications, this injector features hardened alloy steel internal components, precision machining, optimized spray patterns and corrosion-resistant materials, with every unit undergoing factory testing to meet OEM-level performance standards. It is compatible with all CAT C15 variants including industrial, marine, generator and power unit configurations, and cross-references to 249-0712, 295-1411 and 328-2576 part numbers. It supports equipment across mining, construction, marine, oil and gas, power generation, transportation and agriculture sectors worldwide.

When installed following Caterpillar service manual guidelines, the 10R-8500 delivers measurable operational benefits: higher combustion efficiency, lower fuel consumption, reduced emissions, increased horsepower, improved cold starting and better throttle response. Routine preventive maintenance follows a structured schedule: fuel filter inspection every 250 hours, injector testing every 500 hours, fuel system cleaning every 1000 hours and full injector diagnostics every 2000 hours, to extend service life for heavy equipment fleets.
