Engineered as a direct replacement for the 3126 Series HEUI fuel system, this remanufactured diesel fuel injector carries the primary OE reference 10R-1257 and cross interchanges with 178-6342, 177-4762, 229-5928, 177-4752 and 101257. Designed for 3126, 3126B and 3126E engines, the injector supports hydraulically actuated electronically controlled unit injection, delivering accurate atomization, calibrated fuel volume and stable cylinder balance across heavy-duty operating cycles.
Each reman injector is processed through ultrasonic cleaning, internal component inspection, seal renewal and flow testing on calibrated benches to verify pulse response, spray pattern and leakage limits. This process supports lower exhaust smoke, smoother idle, improved throttle response and reduced fuel consumption. The injector fits a broad equipment population including Motor Grader 120H and 135H, D5N and D6N dozers, 561N pipelayer, 938G and 938G II wheel loaders, 953C and 963C track loaders, and 325C excavator, making it suitable for construction, mining, agricultural, truck and fleet repair channels.
Recommended for reman distributors, diesel injector rebuilders and export B2B buyers, the unit ships capped and protected against contamination. Buyers should confirm fitment by engine serial number, arrangement number and the injector part number removed from the engine. Replace O-rings, inspect harness and HEUI oil supply, and calibrate with professional diagnostic tools to ensure long service life and balanced multi-cylinder performance.
