original Common Rail Fuel Injector for C13 Engine, Cross Reference 10R-2977, Replacement for OEM 249-0708, 20R-8046, 20R-2437, for Excavator E345C E349D Truck Diesel Parts original new injector

Engineered for the erpillar C13 and C13 ACERT diesel engine platform, the 20R-2437 fuel injector is a heavy-duty injector assembly designed for precise fuel delivery in one of 's most widely used industrial engines. The C13 is a 12.5-liter inline six-cylinder diesel platform rated between 287 and 400 kW (approximately 385–536 hp) depending on configuration, and it relies on consistent injector performance to sustain power output under continuous heavy-load operation in construction, mining, transportation, power generation, and marine support environments.
This common rail / electronic diesel injector controls fuel metering, injection timing, high-pressure atomization, and spray pattern into the combustion chamber. Injector condition directly influences combustion efficiency, torque response, fuel economy, exhaust temperature, smoke levels, engine vibration, and starting performance. Built to original replacement standards, the 20R-2437 delivers stable combustion, improved engine response, and dependable long-term operation, making it a practical choice for fleet maintenance, overhaul programs, and distributor stock.
The 20R-2437 (also written 20R2437) is commonly cross-referenced with 249-0708, 10R-2977, 10R-3262, 10R-7236, 10R-1274, 20R-8045, and 20R-8046. Typical appliions include C13-powered excavators such as the 345C, 345D, and 349D, as well as heavy-duty trucks, generator sets, industrial power units, agricultural machinery, and oilfield equipment. Because injector calibration may vary by emissions level, ECM configuration, and production year, buyers should confirm the engine serial number, original injector number, and equipment model before ordering to ensure correct interchange.
