Caterpillar C9 Injector 267-9710
Common Rail performance and maximum combustion for your production excavators
Caterpillar C9 Injector 267-9710 (2679710), is a high-precision electro-hydraulic component designed specifically for the common rail (Common Rail) fuel system of engines Caterpillar C9. Equipping earthmoving and extraction excavators CAT 330D And 336D, This injector sprays diesel fuel under extreme pressure directly into the cylinder. With a view to sustainable maintenance and increased profitability, This module ensures micrometric atomization which guarantees maximum engine power, optimal hydraulic responsiveness and a significant reduction in fuel consumption.
Fluid engineering and endurance under heavy loads
Technical transparency is our top priority to preserve the operational continuity of your heavy construction equipment.
-
High-Pressure Spraying: Nozzle equipped with laser-calibrated micro-orifices, spraying diesel fuel into an ultra-fine mist for complete and clean combustion.
-
Ultra-Fast Electromagnetic Actuation: High-tech internal solenoid enabling millisecond switching times for dynamic flow management according to the shovel load.
-
Hardened Internal Components: Needle and injector seat having undergone advanced heat treatment to resist mechanical seizing and impurities in diesel fuel.
-
High Temperature Sealing Kit: Supplied with specific fluorocarbon O-rings, designed to hermetically seal the cylinder head well and withstand extreme thermal cycles.

Kasparts' expertise to secure your productivity in the field
The injector 267-9710 is the ideal technical solution to address difficult starts, power losses, or temperature increases on your C9 engines. By trusting Kasparts for your spare parts, you secure your mechanical investments with durable and reliable components, effectively limiting unplanned downtime.
Technical safety note Replacing injectors on a CAT C9 Common Rail system requires absolute decontamination and cleanliness of the work area. The slightest impurity entering the high-pressure line can instantly seize the nozzle of the new injector. During reassembly, it is imperative to encode the injector's trim code into the electronic control unit (ECM) using CAT ET diagnostic software to precisely adjust the fuel volume injected into each cylinder.
