CATFuel System

1305190 Nozzle As — Cat Engine: 3406C

This is a high-precision nozzle assembly for the engine's fuel injection system, responsible for atomizing fuel into a fine spray for efficient combustion. Manufactured to meet rigorous quality standards, it ensures consistent fuel delivery and spray pattern, unlike a worn nozzle that may leak or produce an improper spray. Operators may observe rough engine running, a loss of power, or black smoke from the exhaust when this nozzle assembly is failing.

Installation & Application Notes

Use clean, filtered fuel — fuel injection components have micron-level tolerances. Prime fuel system before cranking to avoid dry-start damage. Replace fuel filter whenever servicing injection components. Calibrate injectors after replacement if equipment has ECU.

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

Failure Symptoms

Early signs of a failing nozzle include uneven engine idle and a slight decrease in fuel economy. As the issue progresses, the engine may experience noticeable power loss, misfiring, and excessive black smoke. If left unaddressed, continued use can lead to increased cylinder temperatures, potential piston damage, and reduced overall engine efficiency.

Installation Tip

Ensure the injector seat in the cylinder head is clean and free of debris before installing the new nozzle. Avoid dropping or striking the nozzle tip, as this can damage the precise spray holes.

Service Note

Inspect the fuel injector lines for any signs of damage or leaks, and ensure the fuel filter is clean when replacing injector nozzles.
