6738-11-3090 5342352 Diesel Fuel Injector Assembly for Komatsu PC200-7 PC220-7 Excavator 6D102 Engine Parts

The 6738-11-3090 Diesel Fuel Injector Assembly is a replacement diesel engine fuel injection component offered for compatible Komatsu PC200-7 and PC220-7 excavators equipped with selected 6D102 series diesel engines.

Also known as a Diesel Fuel Injector, Engine Injector Assembly, Fuel Injection Nozzle Assembly, or Diesel Injector Kit, this component is designed to deliver fuel into the engine combustion chamber according to the corresponding fuel injection system requirements.

As an important component of the engine fuel system, the injector helps regulate diesel fuel delivery and supports the fuel atomization required for normal combustion.

A correctly matched and properly functioning fuel injector supports stable engine operation, accurate fuel delivery, and the engine's intended performance.

The pictured injector features an elongated black metal body, precision-machined steel nozzle, hexagonal installation section, threaded connection points, and accompanying small installation accessories.

Its mechanical construction is intended for installation in compatible diesel engines requiring the corresponding fuel injector configuration.

JISION supplies diesel fuel injectors, fuel injection pumps, injector nozzles, engine repair components, and construction machinery replacement parts to excavator owners, machinery maintenance workshops, diesel engine repair companies, and international spare parts distributors.
