6745-11-3102 Diesel Fuel Injector Assembly for Komatsu PC300-8 Excavator SAA6D114E 6D114 Engine 6745113102

The 6745-11-3102 Diesel Fuel Injector Assembly is a replacement fuel injection component designed for compatible Komatsu PC300-8 excavators equipped with SAA6D114E series diesel engines.

Also known as a Diesel Engine Fuel Injector, Electronic Fuel Injector, Unit Injector, or Fuel Injection Nozzle Assembly, this component is designed to deliver controlled quantities of diesel fuel into the engine combustion chamber.

As an important component of the engine fuel injection system, the injector supports accurate fuel delivery according to the engine's specified injection timing and operating conditions.

A properly matched and functioning fuel injector helps maintain correct combustion, stable engine operation, and the engine's designed power output.

The 6745-11-3102 injector features a precision-machined metallic body, black electrical connector section, integrated mounting hexagon, sealing components, injection nozzle, and protective sleeve.

Its construction is intended for installation in the designated cylinder head location of compatible diesel engines.

JISION supplies diesel fuel injectors, fuel injection pumps, diesel engine components, hydraulic spare parts, and construction machinery replacement parts to equipment owners, repair workshops, construction contractors, and international spare parts distributors.
