Engineered for demanding industrial diesel fuel systems, the 10R-1268 Reman style fuel injector delivers dependable performance for C10, C-10, C12, C-12, and 3176B diesel engines. This heavy-duty injector assembly is widely referenced under alternate numbers 10R-1268, CA10R1268, 203-7685, 128-8510, 236-4086, CH12082, 874822, 1705252, 3507555, and 20R0056, providing broad cross-reference coverage for buyers sourcing replacement components for construction, mining, and industrial engine platforms.

Measuring 76.2 mm in height, 139.7 mm in width, and 374.65 mm in length, this injector is designed to deliver precision fuel metering, controlled atomization, stable combustion, and reliable engine response under continuous duty cycles. It is commonly specified for heavy equipment applications including 345B, 345B II, 345B II MH, 365B, 365B II, and 365B L excavators, and is suited for repair shops, fleet maintenance operations, diesel engine rebuilders, construction machinery owners, and global parts distributors. Compatibility varies by engine serial number, horsepower rating, emissions configuration, and arrangement number, so verification prior to installation is recommended.

Before fitment, compare part numbers, confirm engine model and arrangement, clean the injector bore and sealing surfaces, and replace all required seals, washers, and O-rings. Inspect the fuel filter, water separator, and fuel lines, then follow the official service manual for torque and calibration procedures. Post-installation checks should include leakage inspection, smoke observation, idle stability testing, and diagnostic code reading to ensure long-term reliability.
