original 20R-2437 Common Rail Diesel Fuel Injector for C13 E345C E349D Excavator Truck Engine Parts 332-1419 249-0708 original new injector

The 20R-2437 diesel fuel injector assembly is engineered specifically for the C13 and C13 ACERT engine platform, delivering precise fuel metering and high-pressure atomization to support efficient combustion across the engine's 287-400 kW / 385-536 hp output range. Built as a direct replacement for original equipment, this injector integrates seamlessly with the engine electronic control module and provides a calibrated spray pattern that promotes clean combustion, stable idle quality, and consistent power delivery. The heavy-duty construction with durable sealing technology ensures long service life under the demanding thermal and pressure conditions found in 12.5 L industrial and off-highway applications.
This injector is compatible with a wide range of machines powered by the C13 / C13 ACERT engine, including excavators such as the 345C, 345D, and 349D, heavy-duty trucks, industrial power units, mining support equipment, construction machinery, agricultural equipment, generator sets, marine auxiliary systems, and oilfield equipment. Authorized cross references include 20R-2437, 249-0708, 10R-2977, 10R-3262, 10R-7236, 10R-1274, 20R-8045, 20R-8046, 249-0705, 249-0713, 232-1198, 239-4908, 253-0608, 292-3666, 332-1419, and 348-4090, allowing straightforward interchange during engine service, field repair, and fleet maintenance operations.
Before installation, confirm the part number, engine serial number, injector code, and equipment model to ensure proper adaptation to the C13 / C13 ACERT fuel system. Clean the injector bore and fuel lines, replace sealing washers with new components, and apply torque values from the official service manual. Prime the fuel system, check for leaks, and perform ECM diagnostic scanning after installation to verify correct cylinder balance and injector performance. Use clean diesel fuel, replace fuel filters on schedule, drain the water separator, and replace the full set of six injectors during major overhaul to maintain balanced fuel delivery and reduced engine downtime.
