Caterpillar original 249 -0705 for C11 C13 Engine 345C 345D 349 352 355 980 980L 980M 982 982M Excavator Loader original new injector

Engineered for Caterpillar C13 and C13 ACERT diesel platforms, the 249-0705 fuel injector assembly delivers precise fuel metering and stable high-pressure injection across demanding industrial, on-highway, marine, and power generation applications. Its precision machined components ensure accurate fuel delivery, while the high pressure design supports consistent atomization for efficient combustion. Hardened internal components and corrosion resistant materials provide long service life under severe duty conditions, and the OEM dimensional accuracy allows direct replacement without modification.

This injector integrates advanced nozzle technology to optimize spray patterns, supporting cleaner combustion and improved engine response. High temperature resistant construction maintains performance in heavy equipment, mining trucks, excavators, wheel loaders, and industrial generator sets operating in harsh environments. Each unit undergoes industrial grade testing to verify flow rate, leak tightness, and spray pattern, ensuring dependable operation for heavy duty trucks, construction machinery, and marine power systems.

Proper maintenance extends injector service life and protects the fuel system. Operators should replace fuel filters at recommended intervals, use high-quality diesel fuel, and monitor fuel pressure regularly. Periodic injector diagnostic inspections, clean fuel system components, and verification of ECM calibration after repair help prevent common issues such as hard starting, rough idle, power loss, black smoke, white smoke, high fuel consumption, engine knock, and misfire related to injector blockage, poor atomization, or internal wear.
