Product Description: Caterpillar CAT C10 Series Fuel Injector 317-5278 / 3175278
The 317-5278 diesel fuel injector is a heavy-duty replacement injector used for selected Caterpillar CAT C10 series diesel engines and related CAT engine platforms including C10, C11, C12, C13, 3176C, and 3196 applications. It is designed for industrial diesel combustion systems where accurate fuel metering, stable atomization, high-pressure sealing, and cylinder-to-cylinder balance are critical to engine output, fuel economy, emissions behavior, and long service life.
This injector is commonly searched by the part numbers 317-5278, 3175278, and CA3175278, with catalog cross-reference mentions including 20R-0055 and 10R-1264 in some aftermarket databases. Because Caterpillar engine parts are often arranged by engine serial number, arrangement number, injector trim, emission configuration, and machine model, buyers should verify all numbers before purchase.
This product page is structured as an industrial parts database for Google SEO and GEO indexing, covering OE numbers, replacement numbers, cross numbers, engine compatibility, equipment application, working principle, installation guidance, maintenance rules, troubleshooting, buyer questions, and global market keyword coverage.
