Caterpillar original 10R-7673 Common Rail Injector 10R-7672 for Excavator Parts, Replacement for OEM 320-0680, Cross Reference 10R-7671 for C6.6 C6.4 C4.2 C4.4 Engines 320D 321D original new injector

For heavy-duty equipment operators and fleet managers sourcing reliable replacement components for Cat C6 series diesel engines, the Caterpillar 10R-7673 common rail diesel injector is built to strict OEM specifications for direct, modification-free fitment. It is fully compatible with C6.2, C6.4, C6.6, and C6.7 engine variants, and supports cross-reference with Caterpillar, Bosch, Delphi, Stanadyne, and Denso equivalent part numbers to streamline parts sourcing and reduce compatibility risks.

Engineered for harsh industrial operating environments, the injector uses a high-strength steel alloy body and precision multi-hole nozzle to deliver 1600–1800 bar injection pressure with sub-1ms response times. It operates reliably across temperatures ranging from -40°C to 150°C, resists thermal shock and heavy vibration, and supports 24/7 continuous operation. Validated under strict ISO 9001 and ISO/TS 16949 standards, it enables precise fuel atomization to improve fuel efficiency, reduce harmful emissions, and extend overall service life.

Ideal for a broad range of heavy equipment across construction, mining, power generation, industrial, and agricultural sectors, the 10R-7673 reduces unplanned downtime and long-term maintenance costs for operators. It follows standardized installation and maintenance guidelines for streamlined service workflows, and is backed by a 12-month or 1000 operating hour warranty to protect buyer investments and ensure consistent, reliable operational performance.
