Caterpillar original fuel injector 211-0565 assembly replacement for C15 C16 3406E C18 truck engines, common rail diesel 10R-8988 211-3023 211-3028 original new injector

The 211-0565 fuel injector is a precision diesel fuel delivery component engineered for Caterpillar C15, C18, C13, and 3406E diesel engines, including the C15 ACERT platform with its inline 6-cylinder, 15.2 L MEUI fuel system. As a direct replacement part, it delivers the correct amount of fuel at the right moment into the combustion chamber, supporting rated outputs of 354–433 bkW (475–580 bhp) at 1800–2100 rpm. The injector maintains the required C-15/C-16 electronic unit injector height dimension of 78.0 ± 0.2 mm for proper installation and combustion performance.

Built with a strong body construction and a controlled spray pattern, this injector provides high-pressure injection performance, precision fuel metering, and reliable atomization for heavy-duty industrial operation. The part-number identity is export-ready and cross-referenced with 211-3028, 10R-7228, 253-0618, 10R-7231, 10R-7213, 291-5911, 10R-7230, 211-3023, 232-1199, 200-1117, 211-3022, 10R-0956, 10R-2782, and 10R-8500, allowing broad search compatibility across global Caterpillar parts databases. The direct replacement design supports fleet maintenance programs serving heavy-duty trucks, excavators, generator sets, mining equipment, construction machinery, marine engines, oil and gas equipment, and agricultural machinery.

Proper maintenance extends injector service life and protects engine performance. Operators should use clean diesel fuel, replace fuel filters on schedule, drain water separators, inspect electrical connectors, and monitor combustion quality through return flow testing, cylinder balance testing, and diagnostic scans. When uniform wear is identified, replacing the injectors as a complete set is recommended for balanced atomization. Before installation, confirm the part number, engine serial number, machine model, and fuel system configuration, then follow OEM torque procedures, prime the fuel system, and verify idle quality, smoke output, misfire behavior, leakage, and fault codes.
