Engineered for demanding diesel powertrains, the 265-8106 fuel injector delivers precision-metered fuel delivery for C9, C9 ACERT, and C9.3 industrial engines operating in construction, mining, marine, oil & gas, and power generation environments. Cross-referenced with 2658106, CA2658106, 235-5261, 238-8092, 242-0857, 254-4330, 254-4339, 254-4340, 266-4446, 267-3360, 267-3361, 267-9710, 267-9717, 267-9722, 293-4073, 10R-2828, 10R-7222, and 10R-4764, this injector offers verified interchangeability for OEM replacement programs and fleet-level rebuild operations.

The unit employs a high-pressure electronic injection architecture rated up to 1800 bar, paired with a multi-hole precision atomization nozzle for superior spray distribution and combustion efficiency. Hardened internal components resist wear under continuous high-pressure cycling, while a corrosion-resistant surface treatment protects against sulfur contamination and moisture exposure. Precision fuel metering maintains accurate injection quantity across variable load conditions, supporting stable performance in 324D, 325D, 329D, 330D, and 336D excavators, C9 generator packages, marine C9 engines, and industrial power units.

Recommended service intervals include fuel quality checks and filter inspection every 250 hours, injector balance and fuel pressure testing every 500 hours, performance evaluation and nozzle spray pattern verification every 1000 hours, and a complete fuel system inspection every 2000 hours. Manufactured to OEM-equivalent specifications, the 265-8106 injector provides dependable long-cycle operation for heavy-duty industrial fleets worldwide.
