The 317-5278 is a heavy-duty replacement diesel fuel injector engineered for selected Caterpillar C10-series and related diesel engine platforms. Designed for industrial diesel combustion systems, it enables precise fuel metering, stable atomization, reliable high-pressure sealing, and balanced cylinder-to-cylinder fuel delivery. These performance traits support consistent engine output, optimized fuel economy, compliant emissions behavior, and extended service life in demanding heavy-duty operating environments.
This injector uses the primary OE-style part number 317-5278, with the hyphen-free alternate format 3175278 and widely used aftermarket catalog identifier CA3175278. Partial aftermarket databases list 20R-0055 (20R0055) and 10R-1264 (10R1264) as cross-reference or remanufactured replacement numbers, while 23670-E0510 appears in some unvetted listings and requires full validation prior to application.
It is commonly cataloged for CAT construction and earthmoving equipment including 14H/140H/143H/160H/163H motor graders, 966G II wheel loaders, 814F wheel dozers, 815F/816F compactors, 572R II pipelayers, and D7R II tractors, across C10, C11, C12, C13, 3176C, and 3196 engine applications. As fitment varies by engine serial number, arrangement code, injector trim, and emissions configuration, buyers must confirm all details against old injector tags, engine/machine serial numbers, and arrangement numbers before ordering.
