Caterpillar original For Caterpillar C13 Common Rail Fuel Injector 20R-2437 332-1419 for Excavator E345C E349D Truck, Replacement for OEM, Cross Reference 10R-2977 249-0708 original new injector

Engineered for Caterpillar C13 and C13 ACERT diesel engine platforms, the 20R-2437 diesel fuel injector is a heavy-duty fuel injection assembly built for consistent, precision performance across demanding operating conditions. Designed for the 12.5L inline 6-cylinder C13 platform (with industrial ratings spanning 287–400 kW / 385–536 hp depending on configuration), it delivers accurately metered diesel fuel at the correct timing, pressure and spray pattern to support stable combustion, optimize engine response, improve fuel efficiency and maintain reliable torque output.

Listed under the alternate part number formatting 20R2437, this injector is commonly cross-referenced with confirmed interchange numbers including 249-0708, 10R-2977, 10R-3262, 10R-7236, 10R-1274, 20R-8045 and 20R-8046. Related C13 family part numbers such as 332-1419 appear in supplier databases but require formal verification before interchange, as injector designs vary by production year, emissions level, ECM calibration and specific fuel system setup.

This industrial-grade replacement component supports a broad range of C13-powered assets, including excavators (345C, 345D, 349D per supplier records), heavy-duty trucks, construction, mining and agricultural machinery, generator sets, marine auxiliary systems, oilfield equipment and industrial power units. It is suitable for fleet maintenance, engine overhaul and equipment repair use cases. Buyers must confirm fitment via engine serial number, original injector number, equipment model and emissions standard prior to ordering to avoid compatibility issues.
