The Caterpillar CAT 386-1774 Fuel Injector Assembly is an original OEM diesel injection component developed for the CAT 3500 Series engine platform. As a core part of the diesel fuel injection system, it meters and atomizes fuel with precision, supporting stable combustion, consistent power delivery, and efficient fuel consumption under continuous heavy-duty operation. Manufactured to Caterpillar OEM quality standards, the assembly ensures direct fitment and dependable interchangeability with the factory-installed unit.
This injector assembly is engineered for Caterpillar 3512B, 3512C, 3516B, 3516C, 3508B, and 3508C engines, covering generator sets, marine propulsion, mining equipment, oilfield machinery, and industrial power systems. The OE number 386-1774 cross-references to 3861774, CAT3861774, 20R-1282, 20R1282, 11R-0667, 11R0667, 392-0222, and 392222, giving purchasing teams and parts distributors a complete identification map for procurement, stocking, and cross-brand lookup. Both original and remanufactured (20R-1282) supply options are indicated within this number family.
For B2B buyers serving the power generation, marine, and mining sectors, sourcing the correct injector by verified OE and cross numbers reduces mismatch risk and equipment downtime. The 386-1774 assembly is positioned as a heavy-duty solution for CAT 3500 Series maintenance, overhaul, and fleet support programs. To confirm fitment, buyers are encouraged to verify the engine model and arrangement number against the listed cross references before ordering.
