Perkins original Diesel Fuel Injector 268-1839 10R-7225 20R9079 387-9427 295-1411 for CAT C7 C9 330C 324D 325D Excavator  original new injector

The Perkins C7 C-7 ACERT fuel injector is a precision-engineered replacement component carrying OE number 268-1839 and CA2681839, also referenced as 2681839, 268 1839, 268/1839, 268.1839, and 268_1839 across cross-reference catalogs. Built for the Perkins C7 / C-7 / C7 ACERT 7.2 L inline 6-cylinder diesel platform, it operates within the 168–224 bkW and 225–300 bhp power range at 1800–2200 rpm. The injector is designed around the HEUI hydraulic electronic unit injector fuel system, supporting stable cold starting, consistent fuel delivery, and reduced smoke potential under variable load conditions. Heavy-duty construction with durable sealing ensures long service life in demanding industrial environments.

This fuel injector is widely applied across Perkins-powered construction and forestry machinery, including Excavator models 324D, E324D, 325D, E325D, 329D, and E329D, Motor Graders 120K and 140K, Wheel Loaders 950H and 962H, and Wheel Skidders / Forestry machines 525C, 535C, and 545C. It serves as a direct-fit aftermarket replacement for HEUI fuel system components, allowing maintenance teams to restore engine performance without requiring OEM sourcing. Each unit is delivered in export-ready packaging suitable for international distribution and bulk industrial procurement.

For reliable operation, install the injector using clean diesel fuel, regularly replace fuel filters, drain the water separator, maintain correct engine oil pressure, keep the air filter clean, and inspect electrical connectors for corrosion or loose pins. Common failure symptoms that indicate replacement include hard starting, rough idle, black or white smoke, power loss, misfire, and ECM fault codes. Always verify the engine serial number and confirm that 268-1839, 2681839, or CA2681839 matches the application before installation.
