Engineered for demanding off-highway operations, the 317-5278 diesel fuel injector delivers precision fuel metering and controlled atomization for heavy-duty engines including C10, C11, C12, C13, 3176C, and 3196. This assembly is cross-referenced under CA3175278, 20R-0055, 10R-1264, and 23670-E0510, making it a searchable replacement solution for fleet maintenance managers, engine rebuild programs, and global parts distributors serving the construction and earthmoving sector.
The injector features robust construction, reliable sealing surfaces, and consistent spray characteristics suited to high-cycle diesel service. Typical equipment fitment includes 14H, 140H, 143H, 160H, and 163H motor graders; 814F wheel dozer; 815F and 816F earthmoving compactors; 966G II wheel loader; 572R II pipelayer; and D7R II tractor / dozer. Because different serial-number ranges and emission configurations may require different injector variants, final fitment should always be confirmed by engine serial number before ordering.
To maximize service life, operators should use clean diesel fuel, replace fuel filters on schedule, drain the water separator, and prevent contamination during installation. Common failure symptoms such as hard starting, rough idle, black or white smoke, high fuel consumption, low power, and diesel knock can be diagnosed through fuel pressure testing, injector balance testing, cylinder cutout testing, and leak-off testing. For high-hour engines, replacing a complete injector set is recommended to restore cylinder balance and optimize combustion efficiency.
