Caterpillar original 10R-0957 Common Rail Fuel Injector for 3406E C-15 C-16 C15 C16 C18 Truck Engine, Replacement for OEM 10R-8500 10R-8501 original new injector

The Caterpillar 10R-0957 fuel injector is a genuine OEM unit injector engineered for CAT C15, C15 ACERT, C16, 3406E, and 3406EE diesel engines. Built with precision machined nozzle components and high strength alloy steel, this injector delivers exact fuel metering for improved combustion efficiency, reduced fuel consumption, and lower exhaust emissions. The heat treated internal components and corrosion resistant treatment ensure long service life under the harshest industrial, marine, mining, and oilfield operating conditions.

This injector is interchangeable with part numbers 10R-0957, 10R0957, 253-0618, 2530618, 249-0712, 2490712, 20R-8058, 20R8058, and 10R0957RX, making it a direct replacement across heavy duty trucks, excavators, wheel loaders, bulldozers, mining haul trucks, marine vessels, power generators, oilfield equipment, industrial compressors, and pumps. Every unit is calibrated to OEM specifications, equipped with an industrial grade sealing system, and subjected to 100% flow testing plus multi-level quality inspection to guarantee stable idle operation, faster throttle response, and increased engine power.

For reliable maintenance, operators should use ultra-low sulfur diesel fuel, replace fuel filters at scheduled intervals, avoid contaminated fuel, monitor engine fault codes, maintain fuel system cleanliness, and perform scheduled injector testing. Diagnostic procedures include electronic system scanning, fuel pressure verification, return fuel flow inspection, injector balance testing, cylinder cut-out testing, ECM communication verification, and inspection of injector electrical connectors to sustain peak performance.
