Engineered as a direct OE-style replacement, the 10R-0955 electronic unit injector delivers calibrated fuel delivery and controlled diesel atomization for Caterpillar C15, C15 ACERT, 3406E, C16, and 3456 diesel engine platforms. The precision-machined nozzle and solenoid-controlled operation ensure stable injection timing under high-temperature and high-load conditions, while the heavy-duty injector body and wear-resistant internal components support long service life in demanding industrial environments.

This remanufactured unit undergoes professional quality control procedures including flow testing and calibration verification, offering a cost-effective alternative to new OE injectors. It accepts multiple cross-reference numbers such as 0R-9803, 211-3025, 176-1150, 191-3005, 170-5252, 203-7685, 20R-0056, 20R-1927, 20R-1930, 10R-1268, 350-7555, EX630955, DELEX630955, LDFC0514, and P248699A, allowing seamless database matching for distributors and fleet operators. The injector is compatible with sealing interfaces designed for heavy-duty on-highway and off-highway equipment.

Suitable for heavy-duty trucks, vocational trucks, construction machinery, mining and oilfield equipment, marine engines, diesel generator sets, industrial power units, and agricultural machinery, the 10R-0955 is available as a single unit or a complete six-piece engine set. Core-return programs, flow-test supply options, and global market availability support B2B procurement, inventory management, and aftermarket service operations.
