Perkins original  20R-2437 C13 Diesel Engine Fuel Injector Common Rail Assembly for E345C E349D Excavator Truck Replacement for OEM original new injector

Engineered for the Perkins C13 and C13 ACERT platform, the 20R-2437 diesel fuel injector delivers precise high-pressure atomization and a calibrated spray pattern that supports clean combustion across the full 287-400 kW output range. Built with heavy-duty internal components, durable sealing, and ECM-compatible electronics, this direct-replacement injector restores factory fuel delivery characteristics while reducing downtime in demanding field operations.

Compatible with excavators such as the 345C, 345D, and 349D, as well as heavy-duty trucks, generator sets, mining support equipment, construction machinery, agricultural equipment, marine auxiliary systems, and oilfield machinery, the 20R-2437 covers broad industrial applications. Each unit undergoes flow performance testing and is available in new aftermarket, remanufactured, original replacement style, or genuine options to meet diverse procurement requirements and fleet service strategies.

Prior to installation, confirm the part number, engine serial number, injector code, and equipment model. Clean the injector bore and fuel lines, replace sealing washers, and correct any contaminated fuel. Apply torque values from the official Perkins service manual, prime the fuel system, inspect for leaks, and conduct post-installation diagnostic scans. Replacing the full set of six injectors is recommended during major overhaul to maintain balanced cylinder performance.
