370-7286-20r-2479 Fuel Injector — Cat 1104D

This fuel injector is a precision-engineered component responsible for delivering a finely atomized spray of diesel fuel directly into the engine's combustion chamber. Manufactured to exact OEM specifications, it ensures optimal fuel atomization and precise injection timing, which is vital for efficient combustion, unlike a worn injector that may leak or spray erratically. Operators may observe rough idling, increased exhaust smoke (black or white), a significant loss of engine power, or difficulty starting the engine if this injector is malfunctioning.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A failing fuel injector may initially manifest as a slight misfire or a rough idle, accompanied by increased fuel consumption. If left unaddressed, this can lead to uneven cylinder operation, excessive exhaust emissions, and potential damage to other engine components due to incomplete combustion.

Installation Tip

Ensure the injector seat in the cylinder head is perfectly clean and free of any carbon deposits before installing the new injector. Avoid rotating the injector during installation, as this can damage the sealing surfaces.

Service Note

Inspect and replace the fuel filter and check fuel lines for leaks or damage when replacing a fuel injector.
