original 128-8510 Common Rail Fuel Injector for C10 C12 Engine 345B 345C Excavator Diesel Fuel Injector Assembly 1288510 10R-0963 0R-9530 Replacement OEM original new injector

Engineered as a direct OEM-equivalent replacement, the 128-8510 fuel injector is a precision electronic unit injector designed specifically for C12 diesel engines operating across demanding industrial, marine, construction, mining, and power generation environments. Cross-referenced with 1288510, 10R0957, 20R2057, and 0R9349, this component delivers reliable fuel atomization and metering accuracy that meet original equipment specifications for global heavy equipment fleets.

Manufactured from high-strength alloy steel and produced under ISO9001 certified quality processes, each injector undergoes 100% flow testing before shipment to guarantee consistent performance in field conditions. Key performance benefits include improved fuel economy, reduced exhaust smoke, increased engine power output, stable idle performance, longer engine service life, and lower total operating costs. The injector is engineered to minimize maintenance downtime for excavators, loaders, dozers, haul trucks, mining trucks, heavy duty on-highway trucks, workboats, fishing vessels, and standby or prime power generator sets running C12 engines.

For optimal service life, use high-quality diesel fuel, replace fuel filters regularly, and monitor engine fault codes. Installation requires thorough cleaning of the injector bore, replacement of sealing components, correct torque per OEM service manual specifications, fuel system priming, and ECM calibration where applicable. A leakage and performance verification test is recommended after installation. Backed by a 12-month warranty, this injector is a trusted procurement choice for B2B fleet operators, workshops, and industrial distributors worldwide.
