Product Description
320-0677: Caterpillar Common Rail Fuel Injector 320-0677 | Reman 10R-7671 Delphi 2645A746 for CAT C6.6/C4.4 – Fits 320D 323D
This common rail fuel injector is a high-quality aftermarket replacement for Caterpillar C6.6 and C4.4 diesel engines (Perkins-based CAT/Perkins platforms). It replaces OE part number 320-0677, cross-referenced to the Cat Reman number 10R-7671 and the Delphi code 2645A746. Each injector is built to OEM specification with a precision-machined nozzle, delivering accurate injection timing, atomization and metering for clean starting, smooth idle, consistent power and lower fuel consumption. High-grade steel components and hardened valve seats withstand sustained common rail pressure, with sealing surfaces and electrical connections matching the original design for a leak-free, bolt-on fit. Every injector is flow- and leak-tested before shipment. Fits Caterpillar hydraulic excavators (320D, 320D L, 323D) powered by C6.6/C4.4 engines. Export-packed, 12-month warranty and responsive technical support. Aftermarket replacement part — not a genuine Caterpillar product. "Caterpillar" and "CAT" are trademarks of their respective owners, used for reference only.
