107-1230 4 Pcs Fuel Injector — Cat 3114 322

This set of four fuel injectors is engineered to precisely meter and atomize diesel fuel into the combustion chamber, forming the core of the engine's fuel delivery system. Manufactured to exacting OEM standards, these injectors ensure optimal fuel atomization and spray pattern, unlike worn injectors that may cause poor combustion and reduced power. Operators might experience rough idling, a noticeable loss of engine power, increased exhaust smoke, or difficulty starting the engine when these injectors are faulty.

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 common initial symptom of failing fuel injectors is a rough or uneven engine idle. If the issue progresses, the engine may exhibit a significant loss of power, increased fuel consumption, and excessive black smoke from the exhaust. Continued operation with faulty injectors can lead to incomplete combustion, potential cylinder damage, and reduced overall engine efficiency.

Installation Tip

Ensure the injector seats in the cylinder head are perfectly clean and free from any carbon buildup before installing new injectors. Overtightening the injector hold-down bolts can distort the injector body or damage the cylinder head threads.

Service Note

When replacing fuel injectors, it is crucial to inspect the fuel lines for leaks and ensure the fuel filter has been recently changed to prevent contamination.
