8N-7005 0R-3418 Fuel Valve Nozzle Replacing for Cat 3304 3306 Engine

8N-7005 Fuel Valve Nozzle Assembly

The 8N-7005 is a new aftermarket pencil-type fuel injector nozzle assembly for Caterpillar 3304, 3304B, 3306 and 3306B diesel engines. It regulates and directs fuel into the combustion chamber to produce the required spray pattern for efficient engine operation.

This product is supplied as the complete long-body direct injection fuel valve nozzle shown in the product images. It is not a separate internal nozzle tip. Common replacement references include 0R-3418 and 8N-7001.

Fitment Confirmation

The nozzle is used across a wide range of equipment powered by Cat 3304 and 3306 Series engines. Common machine references include 235 and 235C excavators, D5H, D6D and D6E track-type tractors, 120G and 140G motor graders, and selected 936F and 950B wheel loaders.

Machine model alone should not be used as the final ordering reference. Confirm the removed nozzle number, complete engine model, engine serial number and fuel-system arrangement because nozzle specifications may vary between different engine configurations.

Installation and Fuel-System Checks

Clean the fuel system and nozzle seating area before installation. Inspect the fuel filters, injection lines, seals and related mounting components to prevent contamination or leakage from damaging the replacement nozzle.

When replacing several nozzles, use units with consistent specification and supply source. After installation, check for fuel leakage, stable engine operation, cylinder balance and abnormal exhaust smoke before returning the equipment to service.
