original 2645A753 New Fuel Injectors for 323D C6.6 1106D-E66TA C6.4 Engine Spare Parts Truck Fuel Filter Replacement for OEM new injector original new injector

Engineered specifically for the C6 engine platform, this common rail fuel injector delivers precise fuel metering and stable injection performance across the full C6, C6.4, and C6.6 engine families. The electronic control method combined with a multi-hole precision nozzle ensures superior atomization, which directly improves combustion efficiency, reduces emissions, and enhances overall fuel economy. With an operating pressure range of 1800–2500 bar, it is fully compatible with modern common rail fuel systems used in hydraulic excavators, wheel loaders, backhoe loaders, generator sets, industrial power units, mining machinery, agricultural equipment, and marine auxiliary engines.

Manufactured from high strength alloy steel with hardened components and an anti-corrosion surface treatment, this injector is built to withstand continuous operation in harsh industrial environments. The direct mount installation design and OEM standard connector type allow for straightforward replacement without modification. Wear resistant construction and industrial grade corrosion protection ensure long service life, while optimized spray patterns support cleaner combustion for environmental compliance. The assembly is a direct OEM replacement for part numbers 2645A753, 330-8752, 7C-6011, and 10R-7217, as well as interchange references 2645A754, 2645A755, CAT2645A753, C6-INJ-2645A753, -2645A753-INJECTOR, and CATC6-2645A753.

Routine maintenance is essential for peak performance. Operators are advised to inspect fuel filters every 250 hours, replace fuel filters every 500 hours, perform injector performance testing every 1000 hours, clean the fuel system every 1500 hours, check injector calibration every 2000 hours, and conduct full injector inspection every 3000 hours. Following this maintenance schedule helps maintain smooth idle, responsive engine operation, and consistent power output throughout the service life of the C6, C6.4, and C6.6 diesel engine platform.
