Caterpillar original Caterpillar C13 C15 C18 D350GC D400GC fuel injector assembly 20R-8045 for excavator genset truck new injector original new injector

Built specifically for the Caterpillar C13 ACERT diesel engine, this replacement injector delivers precision fuel metering and controlled injection timing to restore rated engine performance across demanding industrial duty cycles. The unit is engineered for high atomization quality and reliable operation with low-sulfur, low-lubricity diesel fuels, supporting stable combustion in heavy trucks, vocational vehicles, excavators, loaders, mining machinery, and stationary generator sets powered by the 12.5L C13 platform.

Each injector undergoes strict dimensional and functional inspection to match CAT C13 application requirements, including bore 130mm * stroke 157mm specifications and MEUI-family electronic control parameters. The assembly addresses common field concerns such as rough running, misfire, hard starting, black smoke, power loss, and elevated fuel consumption by ensuring correct injection quantity per cycle. Heavy duty construction provides durability under continuous load, while remanufactured availability helps control total repair cost and reduce sourcing risk for fleet operators and rebuild shops.

Cross references including 10R-1274, 10R-7236, 10R-2977, 10R-3262, 20R-8046, 20R-2437, 239-4907, 239-4908, 249-0705, 249-0708, 249-0713, 292-3666, 332-1419, and 348-4090 broaden interchange coverage within the C11/C13 engine family. Both single-injector and full-set replacement options are available, allowing technicians to select the most efficient service approach based on diagnostic results from cylinder balance testing, return flow testing, and ECM fault code scanning. This flexibility makes the injector a practical global B2B solution for distributors, service centers, and end users maintaining CAT C13 powered equipment.
