Engineered for heavy-duty diesel service, this 178-6342 fuel injector delivers precise HEUI-based fueling for 3126 and 3126B series engines. Cross-referenced with 10R-1257, 177-4762, 229-5928 and CA1786342, it serves as a direct replacement solution for wheel loaders, track loaders, motor graders, tractors and pipelayers operating in demanding construction, earthmoving, mining and quarry environments.
The injector features a hydraulically actuated, electronically controlled design built to original performance standards for fuel metering, diesel atomization and solenoid response. Rugged internal components, precision-ground sealing surfaces and reliable O-ring interfaces ensure stable delivery under high injection actuation pressure. Supply options include new, aftermarket, remanufactured and rebuilt units, available individually or as a six-piece engine set, suitable for 120H and 135H motor graders, 938G II wheel loader, 953C and 963C track loaders, D5N and D6N track-type tractors, 561N pipelayer and IT38G II loader.
For long service life, replace engine oil, oil filter and fuel filters at recommended intervals, drain the water separator, and inspect the injector harness and actuation pressure system. Before installation, verify part number, engine model and serial numbers, clean the injector bore and oil gallery, and fit new seals lightly lubricated with clean engine oil. Follow factory torque values. If hard starting, rough idle, white or black smoke, misfire or fuel-in-oil symptoms appear, read ECM codes, check low-pressure supply and perform cylinder cutout testing to confirm injector condition.
