Caterpillar original 10R-2772 C15 C18 C27 C32 Diesel Common Rail Fuel Injector 253-0618 10R-3264 10R-3265 for E365C E374D Construction Machinery original new injector

The Caterpillar 10R-2772 fuel injector is engineered as a genuine OEM replacement unit for CAT C15, C15 ACERT, C16, and 3406E diesel engines, delivering factory-grade precision calibration and consistent fuel atomization across demanding operating conditions. Manufactured to meet stringent OEM standards, this electronic unit injector incorporates hardened internal components and a high-pressure design that ensures stable injection performance, low leakage rates, and long-term durability in heavy-duty applications. The injector is fully electronically compatible with the engine control module, allowing precise metering and timing for optimized combustion efficiency.

This injector is widely applied in highway trucks, mining trucks, excavators, wheel loaders, bulldozers, industrial power units, marine vessels, and generator sets, making it a versatile solution for fleet operators, construction contractors, and industrial equipment users. The corrosion-resistant construction and robust sealing system allow the unit to perform reliably in harsh environments, including high-temperature and high-load conditions typical of off-highway and marine operations. Cross-reference compatibility with part numbers 10R-2772, 10R2772, 249-0713, 2490713, 328-3562, 3283562, and 10R2772RX ensures straightforward installation and replacement across various equipment configurations.

Proper maintenance of the 10R-2772 injector includes using high-quality diesel fuel, replacing fuel filters at recommended intervals, draining water separators routinely, and avoiding fuel contamination. Regular monitoring of fuel pressure, injector resistance, and ECM fault codes helps identify potential issues early, while periodic inspection of return fuel flow and nozzle condition ensures continued injection accuracy. Following these maintenance practices maximizes injector service life, maintains engine performance, and reduces the risk of unplanned downtime in critical industrial and mobile equipment applications.
